Rooted in Knowledge: Horticulture at the NEORSD

WEBVTT
00:00:00.201 --> 00:00:02.870
When you were a kid, did your parents read you the Giving Tree?
00:00:02.870 --> 00:00:03.814
Oh boy, no.
00:00:03.814 --> 00:00:05.219
By Shel Silverstein no, Did you read that?
00:00:05.259 --> 00:00:05.339
book.
00:00:05.339 --> 00:00:07.326
No, we didn't read a lot in my house.
00:00:07.326 --> 00:00:10.006
They just kind of threw us outside.
00:00:10.006 --> 00:00:15.669
My mom would put a sandwich on the back steps A sandwich on the back steps, so there'd be a plate.
00:00:16.000 --> 00:00:17.202
And it was either you or the dog.
00:00:17.222 --> 00:00:31.367
whoever got there first, yep whoever got there first I Heights, and when I moved down that way I didn't really understand that people didn't have, I mean I guess I did, but I didn't understand that people didn't have just area behind their house.
00:00:31.367 --> 00:00:32.853
Because I had hundreds of acres behind my house.
00:00:32.853 --> 00:00:38.470
I mean we didn't own all of it, but there was probably 600 untouched wood acres behind my house, so I just-.
00:00:38.670 --> 00:00:39.332
That's amazing.
00:00:39.380 --> 00:00:40.000
We'd just go.
00:00:40.000 --> 00:00:40.680
So no.
00:00:40.680 --> 00:00:42.662
When I was younger, they would just say get out.
00:00:43.945 --> 00:00:45.146
You'd leave in the morning.
00:00:45.146 --> 00:00:46.787
Yeah, you walked outside at 7.
00:00:46.908 --> 00:00:50.271
And then, yeah, there'd be lunch sitting out somewhere around noon and you'd eat.
00:00:50.290 --> 00:00:53.134
That's so funny and you know, wash your hands at the hose.
00:00:53.134 --> 00:00:54.816
Sandwich on a plate on the steps.
00:00:54.816 --> 00:00:58.243
The door's locked.
00:00:58.243 --> 00:01:01.451
This is Clean Water Works a podcast about.
00:01:01.631 --> 00:01:02.131
Clean water.
00:01:03.179 --> 00:01:03.420
I'm Mike.
00:01:03.540 --> 00:01:04.563
Uva and I'm Donna Friedman.
00:01:04.923 --> 00:01:09.593
Back again after a slew of winter illnesses and cancellations.
00:01:09.692 --> 00:01:10.233
So much fun.
00:01:10.233 --> 00:01:12.567
So we have Joe Dwyer.
00:01:12.567 --> 00:01:14.989
He's our horticulturalist lead.
00:01:14.989 --> 00:01:16.825
That's a hard word to say.
00:01:16.825 --> 00:01:22.606
Horticulturalist lead in our swim department yeah, yeah, our stormwater inspection and maintenance group.
00:01:23.168 --> 00:01:23.469
Hi Joe.
00:01:23.469 --> 00:01:25.284
Hi Thanks for joining us today.
00:01:25.284 --> 00:01:26.167
Thanks for having me.
00:01:26.700 --> 00:01:28.545
Joe, can you tell us a little bit about yourself?
00:01:28.545 --> 00:01:29.668
Sure.
00:01:29.909 --> 00:01:30.691
My name is Joe Dwyer.
00:01:30.691 --> 00:01:36.632
I'm originally from the far east side, in a town called Thompson which is 20 minutes east of Chardon.
00:01:36.632 --> 00:01:42.653
I was a golf course superintendent for 17 years.
00:01:42.653 --> 00:01:45.507
I started in horticulture.
00:01:45.507 --> 00:01:58.953
I got a degree in horticulture but I did nursery work and the opportunity came to try to turf and I did that for a long period of time and then I decided to switch into urban forestry and then from urban forestry to here.
00:01:58.953 --> 00:02:00.501
What is horticulture.
00:02:01.381 --> 00:02:04.263
What's the difference between horticulture and like botany or Horticulture?
00:02:04.304 --> 00:02:05.484
What's the difference between horticulture and, like botany?
00:02:05.484 --> 00:02:09.229
It's just kind of a broad term, so horticulture covers all of it.
00:02:09.229 --> 00:02:16.876
So you can kind of shove, trees, plants, nursery work, landscaping it all kind of falls under horticultural.
00:02:16.876 --> 00:02:18.137
Okay, that's helpful.
00:02:18.137 --> 00:02:23.318
How'd you get into that?
00:02:23.318 --> 00:02:31.287
It was just a high school job that I started with and then didn't really know what I was going to go to school for Football scholarships dried up because I broke both my legs.
00:02:31.306 --> 00:02:32.810
Oh man, my senior year Good ones.
00:02:33.390 --> 00:02:35.574
Yeah Well, different six weeks from each other.
00:02:35.819 --> 00:02:35.980
What so?
00:02:36.001 --> 00:02:37.747
I had a plate put in and then I played.
00:02:37.747 --> 00:02:41.729
Six weeks later I got back into the season because it was my senior year.
00:02:41.729 --> 00:02:42.390
They let me play.
00:02:42.390 --> 00:02:47.348
Oh, my play and then I broke my femur in the last game that must have been a rough year.
00:02:47.508 --> 00:02:48.191
It was a rough year.
00:02:48.211 --> 00:02:56.141
There's a lot of casts so so, yeah, so that was the only plan was to play football in school, not really what I was going to do in college.
00:02:56.141 --> 00:03:06.412
So I decided to do community college for a year and I started working at a nursery where I knew the owner and kind of really loved doing that stuff.
00:03:06.412 --> 00:03:09.128
And then, as I did that, I finished my horticulture degree.
00:03:09.128 --> 00:03:16.794
There really wasn't a lot in at that time like fields, like parks and stuff weren't really there, just weren't a lot of jobs.
00:03:16.794 --> 00:03:22.568
Not to age myself, it really wasn't a line that you went to.
00:03:22.568 --> 00:03:32.412
So from horticulture or nursery work you went into sales or you went into growing, just like I said, got the opportunity to kind of move into turf and try that.
00:03:32.960 --> 00:03:34.066
Really enjoyed the golf course.
00:03:34.066 --> 00:03:38.325
Mowing grass and preparing a golf course for people is fun.
00:03:38.325 --> 00:03:42.133
But I kind of wanted to be more on the environmental side.
00:03:42.133 --> 00:03:48.893
So the opportunity showed up with City of Braxville for their urban forester.
00:03:48.893 --> 00:04:02.509
So I went there, I got my certified arborist through the ISA and continued and got TRAC certified, which is Tree Risk Assessment Qualification, and took over their urban forestry department.
00:04:02.509 --> 00:04:04.625
And then eventually that led me to here.
00:04:05.105 --> 00:04:05.707
That's great.
00:04:05.707 --> 00:04:07.132
What's ISA?
00:04:07.800 --> 00:04:09.425
International Society of Arboriculture.
00:04:09.425 --> 00:04:13.088
Oh okay, so it's kind of the standard for arborists.
00:04:13.620 --> 00:04:15.568
And what kind of work are you doing now at the sewer district?
00:04:16.141 --> 00:04:18.334
So I work on the GI sites.
00:04:18.334 --> 00:04:20.399
Green infrastructure, green infrastructure, yeah.
00:04:20.399 --> 00:04:40.435
So those are the basins kind of on the outer ring of east side of Cleveland, so they collect stormwater, take it out of the combined sewers in hopes that it would give us a little more time to treat that water before it makes it in and rushes straight out.
00:04:41.014 --> 00:04:41.896
Yeah, so that's part.
00:04:41.896 --> 00:04:50.305
Those are our green infrastructure sites that are part of our appendix three.
00:04:50.326 --> 00:04:51.889
Thank you, is that right?
00:04:51.968 --> 00:04:53.872
This is why you work in a team, folks.
00:04:53.872 --> 00:05:01.440
Yeah, so those are our appendix, three sites, part of our consent decree with the EPA, and so your team maintains those.
00:05:02.122 --> 00:05:11.011
Yeah, so we do work with outside contractors, but we do a lot of the maintenance and then we work on the stormwater project sites as well.
00:05:11.391 --> 00:05:11.632
Okay.
00:05:12.380 --> 00:05:14.689
And then we do some of the maintenance for the larger sites.
00:05:15.000 --> 00:05:21.223
So you're choosing trees and plants and putting them in and then taking care of them.
00:05:21.223 --> 00:05:22.023
Yeah, and then taking care of them.
00:05:22.103 --> 00:05:33.067
Yeah, in some occasions also working with, I've had the opportunity to work with construction on kind of rewriting the plant specs, setting new goals for how you plant trees.
00:05:33.067 --> 00:05:42.533
It's kind of the number one issue with trees going in the ground right now is through various processes and digging.
00:05:42.533 --> 00:05:48.355
What you get is a lot of dirt over top of the ball, over top of the tree taper.
00:05:48.795 --> 00:05:51.336
Yeah, maybe you need to give us the tree 101.
00:05:51.357 --> 00:05:52.538
Okay, parts of a tree.
00:05:52.697 --> 00:05:54.418
Can you walk us through a tree?
00:05:55.339 --> 00:05:55.661
Yeah, sure.
00:05:55.661 --> 00:06:02.374
So in a younger tree you have, essentially, you have the crown, which is where the tree comes out of the ground.
00:06:02.374 --> 00:06:07.612
Then you have what's called the taper, and that's reactive wood from the stem moving.
00:06:07.612 --> 00:06:15.314
So as the wind blows a tree, it'll start to build more wood to stop the tree from being able to sway with the wind or break.
00:06:15.642 --> 00:06:18.706
So is that like right where the trunk meets the ground, that's right where the tree makes the ground.
00:06:19.000 --> 00:06:21.860
Yeah, so you'll see like a triangular shape coming out of the ground.
00:06:21.860 --> 00:06:23.661
Like a triangular shape coming out of the ground.
00:06:23.661 --> 00:06:30.365
Then you come up the trunk to the crown of the tree, which is the leaves and stuff.
00:06:30.365 --> 00:06:32.505
The branches yeah the branches and the leaves.
00:06:32.887 --> 00:06:38.369
Okay, so the taper is the part that has to react to weather and stuff.
00:06:39.028 --> 00:06:43.951
Yeah, so you're saying in windy weather as it blows back and forth, the taper gets stronger.
00:06:44.252 --> 00:06:45.892
Yeah, so that's the stability of a tree.
00:06:45.892 --> 00:06:46.853
Everything's made in there.
00:06:46.853 --> 00:06:50.615
So, as that tree is, I'm sure the hand motions aren't great for the podcast.
00:06:51.314 --> 00:06:58.598
As a tree sways with the wind, it's just a normal function that the tree will start to build that reaction wood and it'll make it stronger at the base.
00:06:58.598 --> 00:07:04.120
That's cool.
00:07:04.120 --> 00:07:08.252
So if you stake a tree for a long time, you affect it If you bury that tree too deep, which I think is what you see.
00:07:08.252 --> 00:07:16.086
So you hear a lot about volcano mulching and that's where the mulch goes way up on the trunk taper and what can happen is rot.
00:07:17.860 --> 00:07:28.312
Because it keeps it wet, keeps the moisture on there because that's what mulch is supposed to do and you also get advantageous roots, which is essentially a bud on the tree.
00:07:28.312 --> 00:07:43.505
That could have been a branch, could be nothing, but when it gets buried below the dirt, it decides it's going to be a root and that root will then start to grow around the tree and then eventually choke the tree off, like around the root ball.
00:07:43.920 --> 00:07:47.334
So around the trunk above the root ball, mm-hmm, so around the trunk, around the trunk, above the root ball, above where it should be.
00:07:47.538 --> 00:08:03.026
Oh boy, so the whole point of that is as you go when trees are planted wrong or misplanted, the tree can grow that advantageous root or you can get dirt built over the top and it basically leads to a tree's mortality.
00:08:03.026 --> 00:08:06.548
Now, that could happen soon.
00:08:06.548 --> 00:08:10.029
It can also happen 20 years down the road, got it?
00:08:10.029 --> 00:08:22.687
So the problem we're having now is we're starting to see trees that were planted 15, 20 years ago with a different standard than we use, and that tree is finally getting to the point where you get a.
00:08:22.687 --> 00:08:24.793
You're starting to see the benefits.
00:08:24.793 --> 00:08:30.572
A large shade tree can take up to 4,000 gallons of stormwater throughout a year.
00:08:30.791 --> 00:08:31.072
Oh, wow.
00:08:31.581 --> 00:08:33.206
The leaves catch pollutants.
00:08:33.206 --> 00:08:41.267
You also have the stormwater benefit of the leaves catching the stormwater, giving it a chance to evaporate, and then you have erosion control.
00:08:41.267 --> 00:08:44.440
Those are the massive benefits to having a large shade tree, and then you have erosion control.
00:08:44.440 --> 00:08:45.780
Those are the massive benefits to having a large shade tree.
00:08:45.780 --> 00:09:03.842
The problem is when we put this time into a tree that's been misplanted and we can't tell what's going on under the ground, we get to the point where we'll get those benefits and then those issues with root girdling or mulch piled up too high and you get a little rot, you start to get insect damage, things like that.
00:09:03.842 --> 00:09:06.524
We never actually get to the benefits of the tree.
00:09:07.423 --> 00:09:09.083
So it's all wasted effort.
00:09:09.384 --> 00:09:14.024
So that's kind of the big problem with trees now and plantings now.
00:09:14.024 --> 00:09:19.265
I think that when you add trees it's kind of the last part of a project.
00:09:19.265 --> 00:09:32.086
So landscaping trees is always at the end of a construction project or a rehab of whatever that is, be it roadsides, stream banks, whatever it is, and everybody wants to be done by that point.
00:09:32.086 --> 00:09:35.347
So the tree goes in and you go, it's planted, it's great.
00:09:35.347 --> 00:09:40.889
But we just don't take the same time that we do with other parts.
00:09:41.649 --> 00:09:46.750
You think about a sidewalk, a city sidewalk, because I did those with the city of Brecksville.
00:09:46.750 --> 00:09:52.880
You come through and you inspect everything, the frames, then you inspect the pour and then you inspect the backfill.
00:09:52.880 --> 00:10:02.479
You know a general sidewalk is, I think, a life expectancy is 40 years and if you're lucky you can get double that, like, if it's insanely good conditions you'll get 80 years.
00:10:02.479 --> 00:10:07.216
A tree is, you know, hundreds of years if it's done right.
00:10:07.216 --> 00:10:09.402
We just don't view it the same way.
00:10:09.402 --> 00:10:39.058
So now, with more of an emphasis on avoiding those issues that I just talked about, there's going to be pre-planting meetings between the contractors doing it, us availability of a planting demonstration, of having it done correctly, showing them how it's done, and then, I think having the inspectors a little bit more briefed in what they're looking for, be that the material, when it comes in looking for any defects from the nursery, the type of stock we get.
00:10:39.058 --> 00:10:48.734
So you know, those advantageous roots is one thing where it can girdle, but when a tree's grown in the nursery in a pot, which I absolutely hate.
00:10:49.255 --> 00:10:51.881
You automatically get a circular motion with that pot.
00:10:52.070 --> 00:10:53.375
Oh, because there's nowhere for it to go.
00:10:53.789 --> 00:10:56.062
So there's some ways that they're trying to fight that.
00:10:56.062 --> 00:10:57.649
But you're going to have those circling roots.
00:10:57.649 --> 00:11:14.654
So making sure that the things are done to straighten those roots out so that they don't continue that circling pattern and eventually choke the tree, and you know, having everybody know that and how to do it and how to find that crown and set it at the right level, know that and how to do it and how to find that crown and set it at the right level.
00:11:14.674 --> 00:11:20.690
So if you don't want us getting trees from nurseries, where they're grown in pots, they would be grown directly in the ground and then dug up.
00:11:20.750 --> 00:11:26.871
Yeah, so we would look at what's called B&B, which is bald and burlapped, so that's where it's tree spaded out of the ground.
00:11:26.871 --> 00:11:43.543
So some of the issues we have and these are bad nursery practices and things that we're starting to try to make sure everybody understands and knows what they're looking for is a lot of nurseries will take container-grown trees and then plant that in the ground so that circling's there.
00:11:43.903 --> 00:11:46.654
It's just way inside of where that tree's dug.
00:11:46.654 --> 00:11:52.798
So you've got to know what you're looking for that whole time so that you can make those changes or just you know.
00:11:52.798 --> 00:11:54.341
Just not accept the stock.
00:11:54.870 --> 00:11:56.153
What kind of trees are we talking about?
00:11:56.153 --> 00:12:02.961
What are the popular or the best choices for Northeast Ohio for the sites that you're overseeing?
00:12:03.330 --> 00:12:05.876
We try to lean towards the native side of trees.
00:12:05.876 --> 00:12:10.956
There's some issues with that which could get me hung after this podcast.
00:12:10.956 --> 00:12:13.682
We're saying I try to stay on the line of that.
00:12:13.682 --> 00:12:20.240
I decided a long time ago that I wasn't going to go one way or the other because I alienate somebody in that argument.
00:12:20.240 --> 00:12:22.590
But we try to stay towards native trees.
00:12:22.590 --> 00:12:41.760
So we're doing, you know, in wetlands, we're doing river birch, we're doing sycamores, some willows, so that will be in the wetter areas and then as we move up we can do other shade trees, we'll do some of the maples, sugar maples, oak trees.
00:12:41.760 --> 00:12:50.831
Now the problem with tree selection right now and this is where I will get into trouble a lot of people believe native's the best way to go.
00:12:50.831 --> 00:13:03.044
The problem is when you look at issues we've had with trees over the last 40, 50 years, 60 years, you know we've lost Ohio chestnut to insects, ash borer yeah.
00:13:04.831 --> 00:13:13.020
All of our ash trees, which was probably one of the most prevalent trees in Ohio, and we've lost elm to Dutch elm disease.
00:13:13.020 --> 00:13:18.022
So when you look at losing those species, you want to keep a diversity.
00:13:18.022 --> 00:13:22.120
So if something does come through we're not losing everything.
00:13:22.120 --> 00:13:40.236
And that's kind of in the urban forestry side, something that a lot of cities learned with emerald ash borer, because ash trees were amazing, great street trees Did really well, grew really well, handled that small amount of soil really well, grew relatively quickly but strong.
00:13:40.236 --> 00:13:44.321
The problem is they planted development after development with ash tree.
00:13:44.321 --> 00:13:47.899
Well, when emerald ash borer came through, it just waved it out.
00:13:48.090 --> 00:13:49.416
So you're starting from scratch.
00:13:49.416 --> 00:13:58.072
So we're working on diversity programs To be diverse enough.
00:13:58.072 --> 00:13:59.677
There just isn't enough native trees left.
00:13:59.677 --> 00:14:00.200
Okay, Honestly.
00:14:00.200 --> 00:14:02.105
And then you look at the changing climate.
00:14:02.105 --> 00:14:14.841
We are getting warmer, so we're seeing trees that did well south of us doing better, trees that were kind of on the borderline did better north of us and here are starting to suffer.
00:14:14.841 --> 00:14:19.605
So we're trying to bring some of those trees from Cincinnati area things like that.
00:14:19.625 --> 00:14:43.876
Yeah, kentucky, yeah, yeah, I've heard that it's as referred to as, like assisted migration, yes, I think, where you're like taking trees that are nearish our climate, but maybe not exactly nearish our climate, but maybe not exactly, but might be our climate soon and planting them here now so that when the climate does continue to change, the trees are more prepared for it because they're from that climate to begin with.
00:14:44.230 --> 00:14:47.697
Yeah, so that's kind of what we work towards.
00:14:47.697 --> 00:14:49.241
So we're working with a lot of those.
00:14:49.241 --> 00:14:59.859
So like, instead of just solely focusing on red oak or white oak, we're looking at shingle oak, which is in that, but it's an oak from.
00:14:59.859 --> 00:15:05.674
You know more in the Cincinnati area we're looking at in the waterways.
00:15:05.674 --> 00:15:13.057
Another great tree that we can use is bald cypress, which has moved up here a long time ago, but it does really well in this climate.
00:15:13.057 --> 00:15:22.075
So those are the kind of trees and then we're looking at different varieties of elms that are now kind of moving back in, but are Dutch elm resistant.
00:15:22.596 --> 00:15:23.460
What is your favorite tree?
00:15:25.673 --> 00:15:28.558
So my favorite tree is Acer griseum, which is paperbark maple.
00:15:29.039 --> 00:15:29.981
Paperbark maple.
00:15:30.202 --> 00:15:33.320
Yep, I just absolutely love the tree ever since I was young.
00:15:33.320 --> 00:15:35.839
It's a very coppery trunk.
00:15:35.839 --> 00:15:37.695
It has an exfoliating bark.
00:15:37.995 --> 00:15:39.721
Like it peels off Mm-hmm, I love that.
00:15:40.371 --> 00:15:45.519
So it's kind of an all-seasons tree so that looks beautiful against the snow when there's no leaves.
00:15:45.519 --> 00:15:49.715
It gets a real light green color through the spring and summer.
00:15:49.715 --> 00:15:51.496
So it's more, I don't know know.
00:15:51.496 --> 00:15:56.123
It just kind of stands out a little bit more than the, than other trees it's got some winter interest.
00:15:56.123 --> 00:15:58.086
Yeah, In the fall it gets a pinky color.
00:15:58.086 --> 00:16:05.535
So instead of going into that red, it kind of gets a yellow pink hue.
00:16:05.556 --> 00:16:06.740
That's cool, Just kind of unique the whole way around.
00:16:06.740 --> 00:16:21.345
Speaking of winter interest, a thing that I learned Upper Ridgewood, our basin project, you know, when we originally brought that design to the residents and city council, one of the things that the residents wanted was that winter interest.
00:16:21.445 --> 00:16:22.186
It's trending now.
00:16:23.153 --> 00:16:32.321
I just I was like I don't, I don't know it's going to have native plants in it and I wasn't really thinking about, like through the seasons, what everything would look like.
00:16:32.321 --> 00:16:34.677
I was just more thinking about like the seasons, what everything would look like.
00:16:34.677 --> 00:16:36.380
I was just more thinking about, like you know, habitat.
00:16:36.380 --> 00:16:39.048
But it is a really important part of the project.
00:16:39.048 --> 00:17:11.182
When you're planting in these urban areas and people are using these spaces which might be the only green space near their properties for their recreation during the winter, you know they're going out, they're walking their dog around this site that we've created, and so having that winter interest whether it's color or berries or leaves still being out on the trees or whatever, it did end up being really important and I think taking that resident feedback and that community feedback made the project a lot better.
00:17:11.182 --> 00:17:17.915
But can you talk about some species that you know in the winter are not as sad as some of the species?
00:17:17.935 --> 00:17:19.378
we have absolutely so.
00:17:19.940 --> 00:17:33.135
There's always evergreens, so you'll have um spruce trees and and, uh, some of the pines yeah I think any of the so shade trees, any of the exfoliating bark ones are a big winter interest.
00:17:33.135 --> 00:17:43.981
So sycamore, you know, paperbark, maple, river birch, so those are the ones where you get that kind of tearing and it just looks really cool against the snow.
00:17:43.981 --> 00:18:04.990
Evergreens that always have interest, hollies, those type of like shrubbery plants that have it, of like shrubbery plants that have it, and then the winter berries like Ilex, or even Hawthorns sorry, that'll have that red berry that it kind of holds throughout the winter and gives you a nice contrast against the snow.
00:18:05.109 --> 00:18:06.174
Do you have trees in your yard?
00:18:06.730 --> 00:18:08.156
I have a lot of trees in my yard.
00:18:08.237 --> 00:18:08.478
Yeah.
00:18:08.789 --> 00:18:19.260
Yeah, I have a very small yard and I have every cool tree that I see, so yeah, there's not enough room, so I actually have four Dawn Redwoods of different varieties.
00:18:19.361 --> 00:18:19.781
That's cool.
00:18:20.570 --> 00:18:33.461
So I have some yellow leaf ones, I have some green leaf ones, I have a variegated blood good which is an upright Japanese maple, I have a creeping blood good, I have a weeping green leaf lace leaf and I have an Acer griseum.
00:18:33.740 --> 00:18:35.536
Can't help yourself, all on a postage stamp.
00:18:35.630 --> 00:18:39.260
Yeah, and I change things a lot, that's fun, that is fun.
00:18:39.470 --> 00:18:42.980
So we had some pretty big storms last year.
00:18:42.980 --> 00:18:48.261
We did it hit a lot of trees over at our Easterly wastewater treatment plant.
00:18:48.261 --> 00:18:51.671
Did they call you in right away Like Joe, get over here.
00:18:51.671 --> 00:18:52.090
We got trees down.
00:18:52.111 --> 00:18:55.914
Yeah, they bring in to look at them for risk and then to kind of assess the trees.
00:18:55.914 --> 00:19:00.298
So you know, seeing what needed to come down right away, what could wait.
00:19:00.298 --> 00:19:08.585
So the problem with a lot of those trees at Easterly is they are large oak trees and we have a disease called oak wilt.
00:19:09.506 --> 00:19:09.945
Oak wilt.
00:19:09.945 --> 00:19:11.386
Yeah, oh wilt Wilt.
00:19:15.112 --> 00:19:16.196
Yeah, oh, wilt Wilt.
00:19:16.196 --> 00:19:17.281
Yeah, it's spread by spores.
00:19:17.281 --> 00:19:23.714
It's spread during the growing season but it's not spread kind of in that off season.
00:19:23.714 --> 00:19:27.083
So you try to do your trimming and stuff when the tree's dormant and the sap's not flowing, so over the winter.
00:19:27.083 --> 00:19:32.538
The problem is when you have a storm like that you have to come through and clean that up.
00:19:32.538 --> 00:19:33.441
So you're making cuts.
00:19:33.441 --> 00:19:36.557
The trees are open so you want to limit the amount of risk.
00:19:36.557 --> 00:19:47.385
So if something can wait, like it's not a hazard to anybody, you kind of want to give it till fall to do any more damage to that tree or open it up to something like oak will.
00:19:47.385 --> 00:19:49.234
So that's spread.
00:19:49.234 --> 00:19:51.931
It's spread by spores in the air.
00:19:51.931 --> 00:19:56.455
But the two most common ways it's spread are root-to-root contact.
00:19:56.455 --> 00:20:01.380
So if you have one in the area that's infected and the roots touch each other.
00:20:01.380 --> 00:20:07.946
But honestly the most common way is uncleaned tools moving from one area to another.
00:20:08.166 --> 00:20:08.446
Yeah.
00:20:09.788 --> 00:20:19.505
Trimmers on roads take out a whole row of old oaks because they never clean their equipment from tree to tree and they trim at the wrong time of the year.
00:20:20.111 --> 00:20:22.866
Suddenly, you lose 40 trees in a row.
00:20:22.866 --> 00:20:24.213
That's horrible Cross-contamination kind of.
00:20:24.213 --> 00:20:24.374
Thing.
00:20:25.309 --> 00:20:42.756
Well, they say that about cleaning off your wader boots when you're coming out of streams too, because a lot of times it's the bottom of your boots that are carrying invasives from one stream to another, so that was something we were trained in when we were in WQIS Water Quality Industrial Surveillance.
00:20:43.411 --> 00:20:46.819
This time of year, you know the seasons are changing.
00:20:46.819 --> 00:20:48.914
It's kind of gray, nothing's green yet.
00:20:48.914 --> 00:21:09.953
Especially driving downtown the Inner Belt, things just look bleak compared to maybe some of our more temperate regions in the country where things are a little more colorful or seem to be more of an effort to do tree plantings and foliage that are a little easier on the eyes than what we have around here.
00:21:09.953 --> 00:21:12.863
Do you feel that way, or driving around, or do you think it could?
00:21:12.863 --> 00:21:13.746
Things could be improved?
00:21:13.786 --> 00:21:16.540
if they just like this is oh, yeah, yeah, I mean, is there a?
00:21:16.601 --> 00:21:27.135
way to to do like cost-effective roadside plantings that last and are a little more vibrant and nicer for the people who have to drive the I-90 every day.
00:21:27.540 --> 00:21:28.645
There's a lot of nice ideas.
00:21:28.645 --> 00:21:39.095
I think the problem with tree planting is taking on too much and understanding that there's a maintenance that has to happen to those trees after they're planted for years.
00:21:39.095 --> 00:21:42.190
I mean, obviously trees need water in the summer when they're first planted.
00:21:42.190 --> 00:21:44.828
You've cut their root systems down to nothing.
00:21:44.828 --> 00:21:46.365
You've put them back in the ground.
00:21:46.365 --> 00:21:49.730
You have to supplement that until they can get established.
00:21:49.900 --> 00:21:51.547
Yeah, like how many years are we talking here?
00:21:52.259 --> 00:21:58.105
So I try to push it to two and then kind of hope that they can make it on their own.
00:21:58.244 --> 00:21:58.545
Yeah.
00:21:58.605 --> 00:22:01.968
But yeah, if you're in a hard condition it can be three, four.
00:22:01.968 --> 00:22:04.150
So there's the maintenance.
00:22:04.150 --> 00:22:05.750
With that that's a hard.
00:22:05.750 --> 00:22:07.492
And then you get into pruning.
00:22:07.492 --> 00:22:16.805
So trees at a nursery are pruned into what's desirable to look at, not necessarily what's best for a tree.
00:22:16.805 --> 00:22:21.140
So you get that real pretty pyramid, look for a tree.
00:22:21.140 --> 00:22:22.502
So you get that real pretty, you know pyramid look.
00:22:22.502 --> 00:22:27.701
And you have to encourage that for the first, I don't know while until you develop a really strong central leader, a leader, yeah.
00:22:27.701 --> 00:22:29.227
So that'll be the straight trunk.
00:22:29.327 --> 00:22:29.528
Okay.
00:22:30.180 --> 00:22:35.763
A normal branching pattern comes off at a I'm not going to say 90 degree angle, but it comes out from the tree.
00:22:35.763 --> 00:22:41.465
When you get a competing leader, they both come up and you get a weak crotch in there.
00:22:41.945 --> 00:22:43.849
And that can lead to splitting and damage.
00:22:43.849 --> 00:22:51.270
As that tree grows more and more, top gets heavier and you don't develop the thickness that you need.
00:22:51.270 --> 00:22:53.364
And then you get included bark.
00:22:53.364 --> 00:22:57.157
So as those trees will grow next to each other, that bark's still there.
00:22:57.157 --> 00:22:58.182
You might not see it.
00:22:58.182 --> 00:23:00.969
You might think that they're one solid tree.
00:23:01.210 --> 00:23:01.691
But it's not.
00:23:01.691 --> 00:23:03.286
They can't grow together.
00:23:03.980 --> 00:23:06.127
So as it gets taller you could lose it.
00:23:06.127 --> 00:23:13.405
So again you're getting to that point where a tree's getting to that point where you're like, oh, that's a tree, it's a real tree, and then you'll have a break happen.
00:23:13.405 --> 00:23:14.965
You open it up to disease.
00:23:14.965 --> 00:23:23.766
The tree won't structurally be sound.
00:23:23.766 --> 00:23:25.630
So you kind of have to develop that with pruning methods.
00:23:25.630 --> 00:23:30.180
So you have that over time and then you just have basic protection from deer cars.
00:23:30.180 --> 00:23:47.951
Everybody believes that it's great to plant trees and that's wonderful, but it's got to be quality over quantity, because we can put in a thousand trees and if they're planted too deep we have no maintenance plans and you know we may end up losing 90% of them.
00:23:47.951 --> 00:23:50.740
So it doesn't serve us a purpose.
00:23:50.859 --> 00:24:00.009
So we want to get that retention rate of those trees and those trees to a point where they're actually serving people and that takes a little bit of babying and work.
00:24:00.009 --> 00:24:08.444
But for roadsides I've seen some great plantings where they do wildflowers between trees and you do these kind of mini things inside the medians.
00:24:08.786 --> 00:24:09.688
So I think it's possible.
00:24:09.688 --> 00:24:14.384
I think you've seen a shift in landscaping over the last, we'll say, 10 years.
00:24:14.384 --> 00:24:17.371
When I started in landscaping it was extremely formal.
00:24:17.371 --> 00:24:22.567
Everybody wanted tightly trimmed it, just everything was the same.
00:24:22.567 --> 00:24:25.528
You know, every house got the exact same planting.
00:24:25.528 --> 00:24:30.412
You had four spireas that got trimmed down to a small ball three times a year.
00:24:30.412 --> 00:24:32.680
You had the same tree on the corner.
00:24:32.680 --> 00:24:38.232
It was usually a river birch planted way too close to a home that would eventually have to come out because it was too big.
00:24:38.740 --> 00:24:52.771
I think you're seeing a change in a lot of people accepting that natural look, Trees and shrubs, plants the way they naturally grow, accepting wildflowers as opposed to annual flowers everywhere.
00:24:52.771 --> 00:25:11.133
But I think you're seeing an acceptance of that, which is great, Because as that starts to change, then we can do things with medians with wildflowers, Because it's always going to look weedier than a formal planting, Because I mean outside of, like that native setting, those plants are weeds.
00:25:11.133 --> 00:25:17.613
So if you have a formal planting bed, a lot of our native plants inside of that, you'd be like you'd be pulling them out.
00:25:17.613 --> 00:25:21.180
Right, a lot of our native plants inside of that, you'd be like you'd be pulling them out, Right.
00:25:21.180 --> 00:25:27.920
So that acceptance of that natural look I think is really good for starting to see that and I think you'll see more medians kind of accept that.
00:25:28.559 --> 00:25:35.549
Yeah, that's definitely a conversation I have all the time with residents and with setting expectations, cause we'll we'll build these projects.
00:25:35.549 --> 00:25:51.636
You know, these stream restoration projects through a neighborhood and we do try to put up some kind of visual barrier so that because it's in a neighborhood and lots of people have very manicured lawns, that's what they're used to in their neighborhood.
00:25:51.636 --> 00:25:59.039
That like split rail fence, you know, it's not really there to keep people out necessarily, it's really there to create a visual boundary.
00:25:59.039 --> 00:26:02.667
So we say this side of this will be mowed regularly.
00:26:02.667 --> 00:26:05.481
The inside, by the stream is the floodplain like.
00:26:05.481 --> 00:26:08.009
That needs to be natural, that's going to look this way.
00:26:08.069 --> 00:26:38.821
And so I think setting that expectation for that aesthetic is something that we're continuously doing and I think I think the metro parks is actually like a good silent partner in this, because I often say, oh, the project is going to look like a natural site, like think about the Metro Parks, if you go into like a park, that's the way it looks, and the Metro Parks do such a good job with maintaining their property that people are like, oh, okay, and so they're able to picture it more as a park setting.
00:26:38.821 --> 00:26:42.612
That's definitely a conversation that we have all the time with residents and I think you're right.
00:26:42.612 --> 00:26:47.672
People are starting to move towards being all right with it not being as manicured.
00:26:48.681 --> 00:26:53.211
So what's a typical day like for a horticulturalist at the district?
00:26:54.361 --> 00:26:54.882
It changes.
00:26:54.882 --> 00:27:01.153
So this year we're going to be taking on a little bit more responsibilities, with a little more hands-on approach at our GI sites.
00:27:01.153 --> 00:27:10.147
So weeding, mowing or just plant maintenance, cage maintenance, that type of thing, or we could end up on a stormwater site.
00:27:10.147 --> 00:27:14.226
Or debris removals smaller debris removals, we may take those out.
00:27:14.226 --> 00:27:16.201
We may be doing deer protection.
00:27:16.201 --> 00:27:26.507
We may be doing plant evaluations at some of the properties we buy out there, just doing regular trash cleanup and maintenance and making sure that those aren't sites that get out of hand.
00:27:26.507 --> 00:27:28.288
Removing a tree, because someone asked us to.
00:27:28.288 --> 00:27:32.851
Seeing if there's a way we can mitigate that risk or maybe explain why we want to retain this tree.
00:27:32.851 --> 00:28:00.396
Doing tree evaluations of sites that might be future constructions, looking at those and seeing if we need to look at different options so that we're not losing the large trees that are giving us the benefits.
00:28:00.759 --> 00:28:04.371
A lot of what I did with the city of Braxville and what I kind of look at now is tree risk.
00:28:04.371 --> 00:28:07.769
So somebody might call me and say this tree is leaning.
00:28:07.769 --> 00:28:09.905
It's leaning towards my house.
00:28:09.905 --> 00:28:14.750
I want to cut it down and they'll come out and they'll be like I love the tree, but it's leaning towards my house.
00:28:14.750 --> 00:28:17.544
It just scares me and I'll go out there and look.
00:28:17.544 --> 00:28:23.211
And then I can look and say, listen, there's no pulling on the roots, I don't see any decay in the tree.
00:28:23.211 --> 00:28:27.422
I don't see anything to be nervous about.
00:28:27.422 --> 00:28:28.786
Do you feel better with that?
00:28:28.786 --> 00:28:30.651
Well, no, it still makes me nervous.
00:28:30.671 --> 00:28:32.023
Well, what if we mitigate that risk?
00:28:32.023 --> 00:28:35.784
What if we, instead of you having somebody come out and cut the tree down?
00:28:35.784 --> 00:28:39.373
What if we trim some branches off to take the weight off that side?
00:28:39.373 --> 00:28:41.865
So now it's not going to hit your house if it falls.
00:28:41.865 --> 00:28:47.467
So it's looking at those different options to help somebody maybe see that the risk isn't quite as bad.
00:28:47.467 --> 00:28:59.046
I think is a really important part of tree work and I think it's the only way we're going to lead to retaining some of these large trees and then doing the protection during construction.
00:28:59.046 --> 00:29:07.365
I've worked with developers during my time in Brecksville that you know they'll turn in a plan that's completely clear cut.
00:29:07.365 --> 00:29:24.089
I'll just send it back to them and say, no, you know, we have to figure out a way to retain some of this and then setting those construction barriers up and the protection zones for the trees you know, so that they're not just going to die two years after the development's done.
00:29:24.800 --> 00:29:48.969
Yeah, that's something that we talk about too a lot in construction is the impact of compaction on the soil to trees that are existing and to trees that are to be planted, and then also like the idea that you need to stay outside of the drip line, which is where the crown If you draw like a straight line from like where the branches end down to the ground.
00:29:48.969 --> 00:29:56.093
That's the drip line, right, yeah, and so you want to be outside of that zone because that's like Ideally.
00:29:56.093 --> 00:29:59.084
The most important root area.
00:29:59.084 --> 00:29:59.525
Right yeah, Okay so.
00:29:59.585 --> 00:30:00.666
Did root area right.
00:30:00.666 --> 00:30:01.268
Yeah, Okay.
00:30:01.848 --> 00:30:02.789
Did your homework, yeah.
00:30:03.531 --> 00:30:03.991
Yeah.
00:30:04.212 --> 00:30:05.714
You already knew this stuff A little bit.
00:30:06.500 --> 00:30:11.532
So a tree's roots can actually extend two to three times the drip line if not further.
00:30:11.799 --> 00:30:12.905
I mean they can go on forever.
00:30:12.905 --> 00:30:16.599
But that most important zone is, yeah, inside that drip line and it depends on a tree.
00:30:16.599 --> 00:30:19.209
You could have one that's really narrow and you need to protect a little more.
00:30:19.209 --> 00:30:20.942
But, yeah, inside that triple and it depends on a tree.
00:30:20.942 --> 00:30:22.763
You could have one that's really narrow and you need to protect a little more.
00:30:22.763 --> 00:30:38.054
But compaction on a construction site is massive because as you lose that pore space, you know, as you're pushing down on that, you lose the places where air is and water is, and if you can't get the water down to it and you can't have those air spaces for the water to fill, the tree is eventually going to choke out.
00:30:38.054 --> 00:30:40.597
For the water to fill, the tree's eventually going to choke out.
00:30:40.597 --> 00:30:44.053
I've been on a ton of construction sites where they left one tree and then they took a dozer and pushed all their extra dirt up against it.
00:30:44.213 --> 00:30:45.295
Yes, I have also seen that.
00:30:45.660 --> 00:30:51.113
So you know it's understanding that, putting up a barrier and then making sure people stay to it.
00:30:51.240 --> 00:30:52.143
What's the term?
00:30:52.143 --> 00:30:59.806
It's such a cool thing when a grouping of trees their canopies will almost touch, but they won't quite touch.
00:30:59.806 --> 00:31:01.846
I forget the name of that.
00:31:01.846 --> 00:31:03.162
Isn't that so cool?
00:31:03.162 --> 00:31:05.205
Friendship, it's friendship.
00:31:05.205 --> 00:31:06.307
I forget the name of it.
00:31:07.229 --> 00:31:07.770
Is that a thing?
00:31:07.770 --> 00:31:08.432
I didn't know that.
00:31:08.432 --> 00:31:09.053
I mean.
00:31:09.053 --> 00:31:09.554
It doesn't make sense.
00:31:09.554 --> 00:31:09.913
It's a thing.
00:31:10.220 --> 00:31:11.405
It can be with certain trees.
00:31:12.441 --> 00:31:13.541
Certain types.
00:31:13.541 --> 00:31:17.306
I don't know if it's respecting each other's space up there, but they'll almost touch.
00:31:17.306 --> 00:31:19.307
But they won't like crowd each other.
00:31:19.307 --> 00:31:21.089
Crown shyness.
00:31:21.089 --> 00:31:34.799
Oh, crown shyness, Crown shyness or inter-crown spacing, is a phenomenon this is Wikipedia everyone In which the crowns of fully stocked trees do not touch each other, forming a canopy with channel-like gaps.
00:31:35.140 --> 00:31:39.048
I think next time people are trying to like shake my hand at a public event.
00:31:39.048 --> 00:31:41.913
I'm just going to be like sorry, crown shyness can't no touchy.
00:31:41.913 --> 00:31:45.106
That's crowd shyness, crowd shyness.
00:31:45.769 --> 00:31:46.451
Trees are weird.
00:31:46.451 --> 00:31:49.030
We learn more and more stuff about them.
00:31:49.030 --> 00:31:49.915
They talk to each other.
00:31:49.955 --> 00:31:52.353
They talk to each other, they do through their roots underground.
00:31:52.453 --> 00:31:52.654
Yeah.
00:31:52.715 --> 00:31:54.881
So yeah, through fungus they can warn each other, right?
00:31:55.101 --> 00:32:12.413
Yeah, through mitochondria or through mycorrhizae, they can actually communicate, tell each other that we need carbon or we need this, and they've done studies where they basically, you know, will irradiate carbon and then they'll find that a tree is passing it to another tree.
00:32:12.413 --> 00:32:18.357
The even more interesting thing is they found oh, I forget her name.
00:32:18.357 --> 00:32:21.203
She wrote the book Finding the Mother Tree, which is a phenomenal book.
00:32:21.203 --> 00:32:22.748
If you want to read something, okay.
00:32:22.867 --> 00:32:25.173
I'll put it in the show notes on our website.
00:32:25.299 --> 00:32:29.811
What she's found is that trees can actually pick out their lineage.
00:32:29.811 --> 00:32:37.832
Their seeds Stop, so they can find their children and, as they're sharing, they can share more with their children.
00:32:37.832 --> 00:32:41.146
What which is kind of crazy when you think about it?
00:32:41.769 --> 00:32:42.349
Joe Dwyer.
00:32:43.152 --> 00:32:43.813
Fantastic.
00:32:43.940 --> 00:32:45.728
This has been a very interesting conversation.
00:32:45.728 --> 00:32:49.594
Do you have any advice for budding horticulturalists?
00:32:50.497 --> 00:32:51.140
Oh See what I did there.
00:32:51.140 --> 00:32:52.405
Did you write that down.
00:32:52.405 --> 00:32:54.824
You did write it down.
00:32:58.092 --> 00:33:21.683
So yeah, I mean, I think it's just get out and get involved and open yourself up to all styles of horticulture and landscape, just so that you can build those conversations with people, because I think that's kind of the biggest part of being an arborist or horticulturalist is being able to express that For anybody who wants to go out.
00:33:21.683 --> 00:33:23.267
And you know help.
00:33:23.267 --> 00:33:26.294
There's tons of groups planting trees, helping in areas.
00:33:27.819 --> 00:33:42.816
So if you're looking to do something like that, my suggestion would be just educate yourself to make sure that you know what you're doing, so that you're not I don't want to say wasting time, but make sure that you know that tree is going to be able to survive if you're out there helping those areas.
00:33:43.961 --> 00:33:45.066
And it's almost Arbor Day.
00:33:45.507 --> 00:33:45.688
It is.
00:33:45.839 --> 00:33:46.521
And Earth Day.
00:33:46.521 --> 00:33:47.846
So this is you know.
00:33:47.846 --> 00:33:49.651
Make your plans now, folks.
00:33:49.651 --> 00:33:51.846
Thank you for coming on the podcast.
00:33:52.140 --> 00:33:53.527
Oh, thank you for having me, this was fun.
