What is Good Growing?
Talking all things horticulture, ecology, and design.
00:00:04:23 - 00:00:23:17
Chris Enroth
Welcome to the Good Growing podcast. I am Chris Enroth, horticulture educator at the University of Illinois Extension, coming at you from Macomb, Illinois. And we have got a great show for you today. Have the weeds been just popping up all over the place like in my yard? Yes, they definitely are. And you know, I'm not going to tackle this by myself.
00:00:23:18 - 00:00:29:21
Chris Enroth
I am joined, as always, every single week by horticulture educator Ken Johnson in Jacksonville. Hey, Ken.
00:00:29:23 - 00:00:35:18
Ken Johnson
Hello Chris. The weeds are also starting to pop up in my landscape as well.
00:00:35:20 - 00:00:47:13
Chris Enroth
I and I'm not going to blame the fact that I've become lazy by the end of the season. It's totally their fault. They they shouldn't be there and I'm going to do something about them eventually. Maybe. I don't know. Probably not.
00:00:47:17 - 00:00:50:00
Ken Johnson
But I'll think about it if nothing else.
00:00:50:02 - 00:01:12:09
Chris Enroth
Yeah, that involves like bending over and, I don't know, doing stuff. That's because right now I am just enjoying the fruits of my labor from earlier in the year. I got cucumbers coming out of my ears. Tomatoes, more tomatoes than I know what to do with. Especially the cherry tomatoes. Why do I do this to myself every year?
00:01:12:09 - 00:01:24:18
Chris Enroth
Cherry tomatoes. I should know better. I shouldn't plant, like, ten of them. I should plant one, and I will be fine. Are you doing okay, Ken? Over there in your garden?
00:01:24:20 - 00:01:41:11
Ken Johnson
Yeah, I guess I guess the one benefit of not necessarily procrastinating, but not getting a whole lot planted is we haven't been inundated. Although, I did pick a, one of those reusable grocery bags full of jalapenos. So now I got to figure out what to do with all of those.
00:01:41:13 - 00:01:44:08
Chris Enroth
Hot sauce time. Do you do? Do you guys do hot sauce?
00:01:44:10 - 00:02:00:20
Ken Johnson
We do hot sauce, pickled jalapenos, and we've already made. We've done pickled. We have done hot sauce yet. So we may do some of that. We’ve got some scotch bonnet and other things too. So some really hot stuff maybe mix in with that.
00:02:00:22 - 00:02:18:10
Chris Enroth
Well, I, I know we've already kind of talked about, you know, sort of how we control weeds in our garden. I, in fact, just a few weeks ago, we were talking about cover crops and how you use those to manage weeds in your garden. But but fall is a good time to chat about weeds. In fact, it's a lot.
00:02:18:15 - 00:02:40:06
Chris Enroth
It's the time where I often try to encourage folks to to focus on some of their perennial weeds. You know, they'll call me in the springtime and say, hey, I got all these dandelions popping up. What do I do about them? Can I spray them right now? And I say, well, yes, but if you could wait until fall, you could be more effective in whatever you might be spraying on these weeds.
00:02:40:06 - 00:03:03:11
Chris Enroth
So today we're talking weeds. Weeds in the fall. So I guess Ken, my my question to you, I mean, we know you use cover crops and all that. For some of your weed control, but, you know, are there any other reasons besides maybe a bit more efficient uptake of an, herbicide that we want to focus on?
00:03:03:11 - 00:03:07:00
Chris Enroth
Weeds in the fall?
00:03:07:02 - 00:03:33:08
Ken Johnson
Yeah. So a lot of our the weeds, they are perennial are some of our annuals, weeds, biennial weeds, all these different types of weeds. By the time seed production is happening in the fall or late summer. So if we can either prevent that seed production or remove those seeds, we can prevent the seeds being added to the seed bank and then germinating, the next year or depending on the weed, five, ten, 15, 25 years down the road, depending on how long they can survive.
00:03:33:10 - 00:03:56:20
Ken Johnson
So we can eliminate try to prevent some problems from happening by getting rid of preventing that seed formation or preventing it from getting into the soil. Like you mentioned, herbicides or perennials that moves into the down into the roots. A lot better. And then things like our, our summer or cool season annuals, winter, annual weeds, whatever you want to call them.
00:03:56:22 - 00:04:14:14
Ken Johnson
They're germinating late summer, early fall time frames. So they're starting to grow. They're going to overwinter throughout the winter. And then in the spring, we're gonna have this explosion of growth, which makes it really hard to manage them. So managing them now, again, we can prevent some of those problems right off of that.
00:04:14:16 - 00:04:33:21
Chris Enroth
And and as far as our summer annuals now those are the weeds that germinated in the spring and they've grown all summer. One example I like to give us something like crabgrass maybe even foxtail. That's another example we get we often get to a point later in the season where I'm like, you know what? It's too late.
00:04:33:21 - 00:04:53:13
Chris Enroth
There's no reason to really focus on a summer annual weed this late in the season, because, you know, especially once we get towards mid to late September, Frost is coming. It's right around the corner. It's going to kill that plant more than likely if you haven't addressed it by mid-September. Member it's already dropped that seed or or at least it's set at seed.
00:04:53:13 - 00:05:22:04
Chris Enroth
So you're going to have to like pull it, bag it and get it out of there. Spraying it may not prevent that seed from dropping to the ground and germinating again next year. So I often tell folks, when it comes to summer annuals and fall, let's try again next year. And, you know, we'll, maybe some type of pre-emergent or something when we're dealing with, like, crabgrass or foxtail in a lawn setting, that will help to reduce that amount of weeds.
00:05:22:06 - 00:05:49:20
Chris Enroth
The following year. But, for the fall, you mentioned winter annuals, which is different from summer annuals. And you described it as and I always like to just to say that they, they do germinate in the fall and then they just hang out all winter and they, they, they do almost nothing. And I do have, I do like some winter annuals, especially the ones that turn the fields purple in the spring.
00:05:49:22 - 00:06:19:00
Chris Enroth
And that probably is going to be your hen bit. There's another one called Purple Dead Nettle, that also has purple colors to it. But really, the it's not a big issue with the farmers because they'll either spray it or plow it and they don't have to worry about it. But where I often see an issue with our winter annual weeds is in the vegetable garden, because you're gardening like I'm still gardening might have some cool season stuff that I'm growing through November.
00:06:19:02 - 00:06:38:20
Chris Enroth
I might have some things I'm going to plant late winter, early spring, and now I'm battling these winter annuals, so I guess can. Do you have any tips or advice when it comes to Winter annual, control? Because they, they, they do get in my way when it comes to the vegetable garden this year.
00:06:38:21 - 00:07:03:20
Ken Johnson
So this time of year, they're, they're, they're small. There's a germinating so they're seedlings or they're really small and they're overwintering. They're usually little rosettes, just this kind of cluster of leaves typically not terribly large. So going in and doing manual removal with my hand. If you're at home out disturb something like that, scuffle out or something just to kind of sever that root system because they're not very big, they're not going to you can say they're never going to, but they're more than likely they're not going to survive that.
00:07:03:21 - 00:07:21:10
Ken Johnson
So do it now. It's going to be a lot easier. Probably shouldn't take a whole lot of time. And again, save you that time in the spring, because when it starts warming up in the spring, they're going to start pushing a lot of growth, and management's going to get a little more difficult because they're going to be getting bigger.
00:07:21:12 - 00:07:41:12
Ken Johnson
You know, as their, as they're pushing out new growth, those herbicides, you can still use them. But it's sometimes a little more difficult because they're pushing out growth. And sometimes herbicides aren't quite as effective. As I've been putting down a mulch down this time of year. Help smother them. Or maybe even prevent them from germinating if they need some.
00:07:41:14 - 00:07:43:24
Ken Johnson
Things like that.
00:07:44:01 - 00:08:09:22
Chris Enroth
Well, yeah, I, I very often I, I turn to, like, some type of stirrup hoe or just pulling them out with my bare hands. When the spring time rolls around. But getting them now and in a vegetable garden, you could, you could look and see if you could find any pre-emergent herbicides. I highly doubt there would be anything available for vegetable gardens if you're growing crops in there this fall.
00:08:09:24 - 00:08:36:15
Chris Enroth
So make sure you're reading those labels very carefully. If you do turn towards, an herbicide option, especially in those gardens, vegetable, crops, areas, I, I will add a lot of folks will call me about chickweed, which is another type of winter annual. Very often they find it in the lawn. Now this typically will pop up in lawns where there's been a disturbance.
00:08:36:17 - 00:09:00:21
Chris Enroth
You know, someone might install a fence. Or maybe, you know, some neighbor use spray to kill a little patch of weeds somewhere in your lawn. And instead of lawn grass to fill in, it's chickweed that fills in. Or the dogs might leave a bare patch in the lawn. And what fills in? It's chickweed, which that's pretty much a major portion of my lawn right now.
00:09:00:23 - 00:09:27:17
Chris Enroth
And so chickweed is is a is can be a big issue. So one option you do have, because we're not dealing in a situation where we're growing edible crops. As you could use a pre-emergent lawn herbicide in the fall to prevent that germination of those, those seeds. But you have to make sure the label says you can seed in lawn that it won't try to control.
00:09:27:17 - 00:09:49:18
Chris Enroth
Also, your Kentucky bluegrass or turf type tall fescue, whatever it is that you're going to also be seed because if you apply an herbicide and you don't also try to reestablish a lawn in that situation, well, you're just going to have something else fill in there next year. So make sure if you're doing this for lawns, if you're also fall is a great time for over seeding.
00:09:49:20 - 00:09:59:01
Chris Enroth
But if you're using a pre-emergent herbicide, make sure that you can also over seed. So read all those labels carefully. You got a lot of reading for you this week.
00:09:59:03 - 00:10:23:23
Ken Johnson
As a homework. So and then another one, type of where do you biennial weeds. So these are weeds that are germinating year one. They are they're growing. Is that rosette being that cluster of leaves the overwinter. So they've grown a season overwinter. And that following year will grow some more. And then they'll shoot out that that reproductive the flowers and stuff and reproduce.
00:10:23:23 - 00:10:53:04
Ken Johnson
So you know garlic mustard some of the thistles would be examples of that burdock. So managing those now in the, in the rosette stage can prevent all those issues with that seed formation following year. Again as they're, as they're getting ready to to overwinter while the energy and stuff is going down to the roots, they can overwinter easier to get those herbicides in, and manage them and then prevent those problems next year.
00:10:53:06 - 00:11:09:07
Ken Johnson
Teasing is another one. It's sometimes a biennial. Biennial was also a macro carp perennial. So it it only blooms once but it may take more than one year. So, there's there's all kinds of variation in that as well.
00:11:09:09 - 00:11:40:11
Chris Enroth
Yeah, I have on my, calendar. So we have on our extension website. Website? I believe it is garlic mustard. That is one of our, spotlighted invasive species that we have. And you can actually download a calendar event for October 15th to remind you to do something about your garlic mustard, in the fall, before, you know, it goes through that winter life cycle and just explodes next spring with seeds and spreads everywhere.
00:11:40:13 - 00:12:05:14
Chris Enroth
Then I think we we also sort of tease this a little bit about perennials, dandelions. These perennial ones is, as you described, you know, the better systemic movement of herbicides. So fall they're taking carbohydrates from their leaves and everywhere they're moving them down towards the root system. Put a little bit of herbicide to go along, with the ride.
00:12:05:16 - 00:12:30:00
Chris Enroth
But when we talk about perennial type weeds, ones that people, you know, love to hate, we're talking mostly dandelions, clover, creeping Charlie. Another one would be, however you want to say this. Planting or planting. I hear it both ways. There's a couple different types of that, like narrow leaf plant. And actually, my yard has large patches of plantain or plantain in it.
00:12:30:02 - 00:12:59:09
Chris Enroth
And right now they're all just dust. They're kind of just they they have kind of shriveled up in our dry, summer weather that we've had so far. So they might sprout here once it cools off. And if we ever get some rain. But it it if you are controlling or spraying some type of weed that has already gone dormant or that is gone, more than likely we're, you know, we don't all we don't always say always.
00:12:59:09 - 00:13:25:13
Chris Enroth
We never say never. But spraying an herbicide on non-living plant tissue often results in no effect. So you have to have green living tissue to absorb that chemical, to then translocate it to the root system. Not that that that is an important part of this. Don't just spray the lawn when you don't see any weeds.
00:13:25:15 - 00:13:44:08
Ken Johnson
Yeah, this is an important point. You know, if we get into our or some of our invasive, our woody invasives and stuff, once they've shut all their leaves, the it becomes a lot more depending on the purpose that you're using. Using a full year spray, there's no foliage there. It's not going to do a whole lot of good.
00:13:44:10 - 00:14:06:02
Chris Enroth
Yeah. And for the longest time, I would I would even tell folks when it came to, like, bush honeysuckle control, you know, by the time you get to winter, the leaves are off. I would say, you know, I don't think it's a it's a great idea to do like to cut the stump and then do like a stump treatment of herbicide on that in the winter time.
00:14:06:04 - 00:14:26:21
Chris Enroth
But there are a few looks like studies that show that can still be an effective way to go. So if you do miss some of that, you know, this fall, say if you're trying to control bush honeysuckle, you could still do cut stem treatments in the winter. I still think you probably wouldn't have is a great uptake of that that chemical.
00:14:26:21 - 00:14:32:02
Chris Enroth
But it, it is a recommendation.
00:14:32:04 - 00:14:34:15
Ken Johnson
Yeah. Something's better than nothing.
00:14:34:17 - 00:14:35:04
Chris Enroth
I guess I can.
00:14:35:09 - 00:14:36:12
Ken Johnson
Put it that good category.
00:14:36:15 - 00:15:06:03
Chris Enroth
Yeah. Yeah. Well, Ken, I suppose, switching gears ever so slightly though still related, you know, as we're talking about weeds, there have been some changes to some herbicides this year. And we do kind of have two, instances to share with you. And the first thing, one that I've dealt with a lot with, with people calling in and just kind of confused about, they have a lot of questions.
00:15:06:03 - 00:15:30:20
Chris Enroth
They're not sure why. Their bottle of roundup is giving different directions than it used to in the past. This fact the roundup has changed. Roundup used to be almost synonymous with the active ingredient glyphosate. Especially, you know it well in the homeowner market. And that's really what we're talking about right now, is people who might buy this.
00:15:30:22 - 00:15:54:21
Chris Enroth
I don't know that the proper term is over-the-counter or use. General, use, herbicide and spray it on a lawn or a garden or something like that. So, we're talking about the homeowner market, but glyphosate is out when it comes to roundup, and there are some new active ingredients in it which has changed the label directions.
00:15:54:23 - 00:16:16:14
Ken Johnson
Yeah, I encountered the the spring. I was looking to kill off some grass to do a vegetable garden bed and I, you know, looking through the label and usually it's on the old, roundup. It was, was it one day after spraying, one day you could blend ornamentals. Three days for vegetable crops. And there was no nothing for vegetable crops.
00:16:16:14 - 00:16:23:19
Ken Johnson
Nothing. Ornamentals or woody plants was like 30 days. So I went back to the cover like, oh, there's no there's no glyphosate in this anymore.
00:16:23:19 - 00:16:45:08
Chris Enroth
So it has changed, I guess the old label had, you know, the the old formulation. You know, when we talk about roundup, it had glyphosate in it. And that is the active ingredient as so we always tell people when they're purchasing an herbicide. Look in that little it's in little tiny print all the time. But it has to be on that bottle.
00:16:45:09 - 00:17:26:00
Chris Enroth
It's like by law, required to list the active ingredient. The active ingredient is the thing that does the killing. You know, it is the thing that is doing the the control and glyphosate is for that. They also very often would include hyaluronic acid, which it's sort of like a contact quick knock down herbicide. And I often just say they threw that in there so that when people sprayed, made them feel like something was happening more immediately because it would take up to two weeks sometimes for glyphosate to really, move through that plant's tissue and kill it from, from its root system.
00:17:26:02 - 00:17:31:16
Chris Enroth
So that that's, that's kind of what the organic acid, it was just sort of like a little extra. It's like.
00:17:31:16 - 00:17:33:01
Ken Johnson
Instant gratification.
00:17:33:02 - 00:17:35:11
Chris Enroth
That's right, that's right. We all know that.
00:17:35:13 - 00:17:37:01
Ken Johnson
Results within six hours.
00:17:37:03 - 00:18:11:08
Chris Enroth
Yeah. So I guess it's it's important to note, that this is a brand decision. This is not, mandated. This is voluntary. By by the company that makes roundup. Was that Dow Chemical? These days? I can't keep track. Bear? Yeah, bear. The bear. And so that is been voluntary. You can still get glyphosate. Like, you can go find generic brands of glyphosate, I believe.
00:18:11:14 - 00:18:31:15
Chris Enroth
Will, Oh. I won't even say when I think the date was, but I thought it was turn of the century or 1990 ish when you started being able to manufacture a generic form of glyphosate. And back then, when Monsanto own owned it, their, not copyright, you know.
00:18:31:17 - 00:18:33:24
Ken Johnson
Restriction pen.
00:18:34:01 - 00:18:34:13
Chris Enroth
Patent.
00:18:34:13 - 00:18:37:03
Ken Johnson
That's when there was around 2000.
00:18:37:05 - 00:18:37:18
Chris Enroth
2000.
00:18:37:18 - 00:19:05:07
Ken Johnson
And there. Okay. Yeah. So there's the, the quote unquote generic glyphosate guess. Yeah. Maybe I think that will depend on where you're looking at. You know I think you're big or you're big box stores maybe a little more difficult. But if you're going to a, a nursery or, there's something somewhere that's got a little more diverse options as far as herbicides and stuff, you'll probably be able to find it.
00:19:05:07 - 00:19:08:24
Ken Johnson
And, you really can find anything on the internet.
00:19:09:01 - 00:19:09:18
Chris Enroth
If that's right.
00:19:09:22 - 00:19:11:16
Ken Johnson
Barely any glyphosate.
00:19:11:18 - 00:19:42:05
Chris Enroth
That's right. Yep, yep. You can always find anything you need and get on watch lists. So, I often say, you know, you could go to local garden centers. It's pretty easy to find different things. Or especially, you know, if you have, like, a farm store that has like a forestry section where they might have a lot of these generic active ingredients in bulk and so that so we'll still be recommending we'll probably still have glyphosate in a lot of like extension recommendations.
00:19:42:07 - 00:19:51:24
Chris Enroth
It's just not going to be synonymous with roundup anymore, which I think is going to take some time and some adjustment, probably for us and for consumers.
00:19:52:01 - 00:19:58:00
Ken Johnson
Yeah, it's like seven in Kabul. Yes. I don't even know seven has Kabul on it anymore.
00:19:58:02 - 00:20:10:18
Chris Enroth
I don't think it does. Yeah. It's something different now. But yeah, it that that's where our brain it makes that that relationship because it was so common and it's so commonly used in the past.
00:20:10:20 - 00:20:33:14
Ken Johnson
So and so Purdue extension it was just thing for Purdue. Put an article out I would say the one roundup isn't roundup. Clearing up the confusion between products. And they list some of the different formulations. Now, I will put this article in the show notes so everybody can read it for themselves. But so some of them as I'll try a clip here.
00:20:33:16 - 00:20:35:22
Ken Johnson
So this is a Oxon.
00:20:35:22 - 00:20:37:23
Chris Enroth
Yeah. It's like a broadleaf herbicide.
00:20:38:01 - 00:21:03:24
Ken Johnson
Raleigh versus, asa fab, which is a grass herbicide. Die quite, which is a kind of a burn down type herbicide. Really quick acting. And then a massive pick, which is a little more as a more broad spectrum. So you've got so just glyphosate now you've got four different active ingredients in this particular one, they're talking about, and then they've got some for, for lawns.
00:21:03:24 - 00:21:24:06
Ken Johnson
So these are all going to be specific to broadleaf. So I'm CPA. Quinn clawback dicamba. So center zone. So all of these are, broadleaf or this is not sedge. So again you've got you've got more mixtures now than just a single active ingredient. And a lot of these.
00:21:24:08 - 00:21:48:22
Chris Enroth
Yeah. And I think the one that has gotten a lot of questions. So, it's very common for people to have used glyphosate in the past to maybe prep a landscape bed and they might spray, like the, say, in the bed area, they'll kill the grass, and then they'll come in with, like, shrubs and trees and other perennials and things to, to create a landscape bed.
00:21:48:24 - 00:22:09:24
Chris Enroth
But now that the instructions say you have to wait 30 days for planting any type of woody material. So the question is really been like, why? Why is that changed? And that's really from what I've read, is is the active ingredient try clip here. Try clip here. As Ken said, it's a broadleaf herbicide. It's really good at killing woody plants.
00:22:10:01 - 00:22:36:24
Chris Enroth
And is very often something that might be recommended for going after, like, invasive species like our bush honeysuckle or autumn. All of you might use triangle here or glyphosate. Both of them do that very well. But Lapeer is a little bit different in that it's more mobile in the soil and a bit more persistent in the soil, whereas glyphosate, what would happen to that is you would spray it and it would just bind to soil particles and it really wouldn't move that much.
00:22:36:24 - 00:22:58:14
Chris Enroth
And so long as you had sunlight like a UV light, it would break down within a, you know, span of a few days, at least below a threshold that could hurt a woody plant. And so that's really the big change that I see. A lot of people have any questions about. Why can't I come in after I spray?
00:22:58:14 - 00:23:09:00
Chris Enroth
This is can describe a day or two and plant my, my trees and shrubs like I've always done. Well, it's more than likely it's that tri clip your active ingredient.
00:23:09:02 - 00:23:27:17
Ken Johnson
Yeah. So go back to read your labels to make sure you know it. Depending on what you're using and what you're going to be using it for that your your you're not setting yourself up for for headache and heartache down the road by planting in it too soon. If you're doing a, you know, a lawn or illumination to, to plant stuff.
00:23:27:17 - 00:23:32:14
Ken Johnson
So, I guess it's good to get the questions because people are reading the labels.
00:23:32:16 - 00:24:00:11
Chris Enroth
I know I'm I'm happy to get these questions because they're, it does go to show that the, the folks who are reading the label, but I there is a one formulation of roundup that still does contain glyphosate, and it's actually a combination of tri copper and glyphosate. And that is their tough brush killer formulation. I think what do they say here in the Purdue article?
00:24:00:11 - 00:24:17:17
Chris Enroth
They call it poison roundup, poison ivy and tough brush killer. And it says, yeah, it contains both of those active ingredients, tri beer and glyphosate, which is one that we are very often recommend for those woody invasives.
00:24:17:19 - 00:24:40:02
Ken Johnson
And there's one more herbicide, that's been in the news. That's that's all our EPA. And for this one, the EPA, ABA is in charge of all of us centered stration in the US. So they say what what goes and what doesn't. They have issued, and it was an emergency stop order use for Dec, which means you can no longer use it even if you have it.
00:24:40:02 - 00:24:59:17
Ken Johnson
So a lot of times when they when they, they cancel registration or they, you know, stop producing it and no longer for use, you can use up existing stocks. That is not the case. For Deco you cannot use it anymore. You have to dispose of it, without using it.
00:24:59:19 - 00:25:33:22
Chris Enroth
Yeah. And I, I think in the past it was very commonly used as a pre-emergent and lawn herbicides. When the EPA first started having issue with, with, with Taxol many years ago, the company actually voluntary remove voluntarily removed it out of a lot of their lawn herbicides. But there was still, quite a lull between when their, their reports were due in 2016 till when the EPA finally just said, you know, we're going to have we're not going to let you sell this in 2022.
00:25:33:24 - 00:26:10:21
Chris Enroth
And then finally they they did submit reports that showed that there were issues where, especially with farm workers, where that thought can be very can be used commonly in like onions, brussel sprouts and, broccoli. Production. And so a lot of these farm workers, namely women, pregnant women who were exposed to this were showing lower, fetal birth weights, thyroid issues, with, their unborn unborn children and, and a lot of other kind of lifetime incurable issues.
00:26:10:23 - 00:26:35:15
Chris Enroth
And so in light of the information the company finally provided to EPA, and all this other evidence that that they're seeing stopping the emergency stop use, which, that's something that is rarely ever used by the EPA. So it's, it's first time in almost 40 years that they've ever had to use that.
00:26:35:17 - 00:26:54:10
Ken Johnson
Usually it's a phased out. So probably unlikely that people are going to have this. As far as, like a home gardener. Yes. But if you for some reason you do, you're not allowed to use it anymore. And dispose of that. Look up here, you know, clean sweep programs or things like that. In your area.
00:26:54:12 - 00:27:16:14
Chris Enroth
Yeah. Illinois has been doing a much better job at those clean sweep programs. At least where I'm at in McComb, we very often now have it, once a year. But usually it has happened in the spring. But, yeah, you can check out, where the Clean Sweep program will be. Perhaps I don't know if they have their dates for 2025 yet.
00:27:16:16 - 00:27:20:17
Chris Enroth
But at the Illinois EPA website.
00:27:20:19 - 00:27:24:19
Ken Johnson
And there are a couple permanent.
00:27:24:21 - 00:27:49:21
Chris Enroth
And more, more metro kind of areas. They I think they do have some permanent ones. But us here in the rural hinterland, we gotta we gotta wait for our time. That's right. Right. August. Tonia. Well, that was a lot of great information about perennial weed control in the fall. Annual weed control, that is a winter, annual, summer annual.
00:27:49:23 - 00:28:11:17
Chris Enroth
That's the important thing to distinguish. Then of course, our biennials out there and then changes to the herbicides that, at least when it comes to products like roundup very often can be found in a lot of shelves and a lot of garages across Illinois. And then the emergency stop use of Taxol, which probably not in most garages.
00:28:11:17 - 00:28:28:01
Chris Enroth
But if it is, read your product, label active ingredients and make sure you're disposing of that properly. So yeah, lots, lots of great information can I guess maybe I'm a bit more motivated now to go ahead and pull some of that creeping Charlie that I love so much.
00:28:28:03 - 00:28:43:14
Ken Johnson
Yes, it's it's a good time to do it. And don't forget, it doesn't have to just be herbicides. You can you can knock some of the stuff out of a small patch. Easy enough with your hands or a whole, something like that. So it's possible to do it without herbicides too?
00:28:43:16 - 00:29:08:17
Chris Enroth
Yeah, I tolerate the weeds for the most part in my yard. You know, I might smother them. I might pull them. Very rarely will I spray them most often, you know. Will I? I will reserve that for managing some of those invasive plants, you know, that are listed, like bush honeysuckle, like autumn olive. And I just found it in my backyard tree of heaven.
00:29:08:19 - 00:29:22:06
Chris Enroth
And there's a big mama attached to this tree of heaven and way across the way. So I'm like, oh, great. So anyway, we'll talk maybe we'll talk about those invasive species later on this year.
00:29:22:08 - 00:29:25:06
Ken Johnson
Sort of looking for, spotted lanternfly on it, too.
00:29:25:08 - 00:29:45:04
Chris Enroth
That's that's my scouting mechanism. There you go. Yeah. Just got to keep it from flowering. Well, a good growing podcast production of University of Illinois Extension, edited this week by Kent Johnson. And a special thank you to Kent for both editing and hanging out with be talking about them fall weeds and then herbicides. Thank you Ken.
00:29:45:06 - 00:29:49:10
Ken Johnson
Yes thank you Chris. And let's do this again next week.
00:29:49:12 - 00:30:07:06
Chris Enroth
I hope we shall do this again next week. Can you believe it's September? And oh there's so much stuff going on. So we're going to have a couple garden bites for you coming up these next few weeks. So enjoy those. We'll be right back with you the end of the month. Just me and Ken hanging around talking about gardening.
00:30:07:08 - 00:30:26:20
Chris Enroth
So listeners, thank you for doing what you do best. And that is listening. Or if you're watching us on YouTube watching. And as always, keep on growing.
00:30:26:22 - 00:30:33:12
Chris Enroth
As I tell you, recording started when I hit the button and it says, do you want to leave?
00:30:33:14 - 00:30:39:04
Ken Johnson
It's got a little banner. Well, it's just this meeting is being recorded. Okay? Only option is okay.
00:30:39:06 - 00:30:41:22
Chris Enroth
It's okay. I can't stop it.
