rethinking the lawn, with ecological horticulturist dan wilder

THE LECTURE that he’s been giving for a number of years is not-so-subtly called “Kill Your Lawn.”

Ecological horticulturist Dan Jaffe Wilder knows that starting over and creating an entire native habitat instead of a lawn isn’t for everyone. But Dan just wants to grab our attention and get us to start to make some changes at least in the way we care for the turfgrass we do want in our landscapes. And maybe give up a little square footage of it to some other kind of more diverse planting, too, like the wild strawberries (Fragaria virginiana), above.

Alternative, more eco-focused styles of lawn care, along with some lawn alternatives is our topic today. Dan is Director of Applied Ecology at Norcross Wildlife Foundation in Wales, Massachusetts, and its 8,000-acre sanctuary. He’s also co-author with Mark Richardson of the book “Native Plants for New England Gardens.”

a more ecological approach to lawn, with dan wilder

 

 

Margaret Roach: Well, Dan, so you win the prize. The recent article we did together on smarter lawn care and lawn alternative ideas for my garden column in “The New York Times,” last time I checked had close to 1,200 comments from readers. So apparently this is a hot button, which is interesting to me. You probably already know that it’s a hot button.

Dan Jaffe Wilder: Well, I’ve always been a little bit of a troublemaker, and this is one of those troubles that I really like to embrace. It’s a complicated topic and there’s plenty of people who are in it because that’s where they … they don’t know where else to be in terms of, “I’ve got this space, I think it’s supposed to be a lawn, I might as well make it a lawn.” Or maybe, “I inherited a lawn,” how many of us have. And then there’s lots of people who are starting to question that right now. And with these questions comes controversy and confusion and passion, and a touch of ecology hopefully as well.

Margaret: Yeah. So I mean, I guess, the elevator pitch for why one would want to reconsider either how we care for it or what we plant instead of our lawn is because the lawn is this monoculture of non-native grasses, that’s not diverse and doesn’t really serve the ecology. Is that the short pitch?

Dan: I think that’s definitely an important part of it. What I often tell people is that lawns are a whole lot of work, and they don’t give us anything in return. And when I say us, I mean the entire ecosystem, humans being a very important part of it. But the lawns from an ecological point of view are at the very least a waste of space, and in some cases are truly a detriment to the ecological function.

And in many cases they are a lot of work. When I’m willing to put a lot of work into a garden space or really any outdoor space, I want to either know that it’s doing a lot for the ecosystem, or maybe I’m directly benefiting from it. And I find that in most cases, lawns really just don’t fit that anymore.

Margaret: Right. So in the lecture you do [laughter], which is called “Kill Your Lawn,” and in the story we did together, you explained that you have what you call gradients of ecology, by which you rank various shifts, either in the way we care for our lawns or changes instead of lawns that we can make. So it did seem like a no-brainer that almost anyone could do the first gradient level. So tell us what that is, the intro to a more ecological situation.

Dan: Yeah. The gradients of ecology allow us to really look at this on a step-by-step process. And as much as I’ve really enjoyed the kill your lawn campaign–it’s really an eye-catcher–the base message is that you don’t have to go full swing into it if you’re not ready for it. And most people aren’t. And you can start very, very small.

If you simply look at the lawn you’ve got and say, “I’m going to treat this with more ecological sense in mind,” you can go so far as to mow it a bit less, let it get a little bit taller, cut off any fertilizer or irrigation that you might be adding to it. And even that tiny little step is a step in the right direction.

And then the gradients go from there into full scale, wild native ecosystem. With a lot of steps in between that really hopefully makes this something that anybody can tackle. It’s not something where you need to put in 10,000 hours worth of work. If you want to just actually frankly do less, that’s a really good first step.

Margaret: So, doing less… So lawns notoriously use a lot of water, and water’s a precious resource more and more, as we know on the planet. And people use chemicals of various kinds, including as you just mentioned fertilizers on them. So we could back off from watering, let it go dormant in the hot season of the year, things like that. We could just back off from watering.

We could say no to the pre-emergence herbicides, all the chemicals and the fertilizer, and we could mow less. But you’re not saying, just let my lawn grow if I’m in a traditional, suburban lot, because, I mean, that isn’t necessarily going to yield a great thing, is it? I mean, it’s tricky, “unmowing” as I call it [laughter].

Dan: There are a few very, very rare instances where if you simply stop mowing a lawn and stop caring for it, it will turn into something better. But in most cases, and I’m talking 99 percent of the cases out there, if you stop mowing your lawn, what you’re going to end up with is a tall lawn, likely with a few extra weeds mixed in. [Above, native violets, a desirable lawn “weed” to encourage.]

I jokingly call it the plight of the turfgrass in America, in that we’ve got a species or a mix of species that frankly are not well adapted to our environment. And so in order to get these to grow well, we need to water them because they’re used to a higher level of water than we naturally get here. And we get a lot of water. And they’re used to a different level of nutrients than our soils typically have.

So we water them, we fertilize them, we take care of them. And then the odd part is, if God forbid it actually works and the thing starts growing, we immediately break out the mowers and cut it down to size. And when we do that, it restricts the plant’s ability to produce a good root system, because there’s always going to be some balance between the amount of foliage and the amount of root space. And if you’ve got a nice deep root system, the plant can take care of itself. But with our constant mowing, it’s pretty much a plant on life support.

And that’s a whole lot of work, and it’s a whole lot of wasted time as far as I’m concerned.

Margaret: Yeah. So, if I’m going to back off on the water, back off on the chemicals and mow less, 4-inch mowing height, mow every two or three weeks, any ideas on that? And I guess it depends on where you live and the season of the year as well. But we’re talking about higher, not 2 feet high, but we’re talking about raising that deck and shifting that frequency, yes?

Dan: Yes. And I think going by the height is a really good way to go about it.

Margaret: O.K.

Dan: Because depending on where you are and your season and so forth, the height is a consistent thing that’s always going to, it might mean mowing every three weeks for me here this time of year and two weeks for you there, but we’re always aiming for that higher height.

I tell people, whenever possible, at least 3-1/2 inches, 4 is better, but getting up past that, we tend to start losing the benefits of it. And it’s an easy first step because frankly all it requires is doing less work. And that’s not a hard thing for most people to take on.

Margaret: O.K. And say I’m ready to go to the next step, if I’ve accomplished that, and I’m fascinated and getting seduced by this idea–not necessarily ready to kill my lawn completely, but on to the next step. What would be some next steps I could take in those gradients of ecology you described?

Dan: Sure. So you’ve got a few different options, but I think that the standard next step is to look at some of the ecologically sensitive lawn alternatives that are out there. Some of the common ones are things like white clover, or there’s a variety of different products that go under the name, eco-lawn, eco-grass, low-mow, or no-mow grass. You’ll find a variety of different options out there. And these are usually a mix of slow-growing fescues. There’s probably a few natives mixed in, but for the most part, these are non-native mixes.

And what these can provide for us is a lawn that can reduce that maintenance significantly more. To the point where once they’re established, you’re usually mowing this once, maybe twice a season. They do not need rich soil. So standard lawn practices, at least 6  inches of good top soil. In the case of all these low-mows or no-mows, you really just seed it into whatever your soils are, and it’ll be fine.

And then again, once established, there’s no need to fertilize ever, and mowing is very minimal. So it greatly reduces the inputs that would go into a traditional lawn.

And the added bonus to these, as compared to the natives that I think we’ll get to in a bit, is that they’re readily available. They tend to be inexpensive. And they all come with a good set of instructions. And if you follow that instructions, you will succeed. And there is definitely something to be said for that.

Margaret: But you said, “seeded into the soil.” And so I don’t over seed my existing lawn to accomplish this. Is that right?

Dan: That is correct. I’ve tried this many times, just throwing seed into lawn, and you will see some new plants coming up, but you’re not going to really, in a realistic timeframe and to a realistic level, you’re not going to convert a lawn without first zeroing out that lawn to one extent or another. And there’s a variety of different ways to go about doing that.

Margaret: O.K. And maybe we can talk about that, because I know you’re a smotherer [laughter], you’ll have to smother or tarp things, smother them with various things. And maybe we can talk about that. But first, just in terms of these no-mow, low-mow, eco-lawn, a couple of sources maybe for where I could look to see what those products are like that. Have you tried any?

Dan: Yes. I’ve tried a few. There’s a company up north of us in Canada called Wildflower Farm that has an eco-lawn mix. I’ve also worked with, I know that both Prairie Moon and Ernst Seeds carry eco-lawns or eco-grasses. They’re all used interchangeably. And then you can find your standard white clover at just about any organization. Fedco Seeds is where I tend to buy mine when I’ve worked with that.

There’s also a micro-clover out there, which I have not yet worked with myself, which is supposedly shorter and cuter and more dainty. I’ve heard mixed reviews on that one. But I’d love anyone to give it a try and tell me how it went for them.

Margaret: Right. And just important, we just named a few sources, and I can give links to those with the transcript of the show. But regionally appropriate is the other thing. And so if those don’t have mixes that are good for where you are. It can’t be all things to all places in the world in one catalog usually.

Dan: Certainly. I mean, I’m a Northeasterner and my sources tend to lean Northeast. My specific plant knowledge is Northeast-based. And so that means when you’re asking me about sources in California or Arizona, frankly I don’t have a good answer for you. And that’s when you want to reach out to your local experts and start getting a sense of … Local knowledge is extremely valuable for a variety of different purposes, but especially for this. [Native plant organizations are a good place to start. The North American Native Plant Society has links to ones in each state in the U.S. and Canadian province.]

Margaret: Right. And for instance, before you worked at Norcross, you worked a number of years at what was the former New England Wild Flower Society, now Native Plant Trust in New England. And I’ll give with the transcript, again, a link to where people can find organizations, entities, nonprofits like that all over the country and in all the Canadian provinces to research local… That you can get from a non-profit organization, the recommendations of sources in your area. So I’ll give all that.

So back to some of these possibilities. So I could zero out and consider one of these admittedly non-native, but easier to manage and more beneficial and less mowing required, etc., eco-lawns. And what else could I do as a next tier?

Dan: The eco-lawns, their real claim to fame is that the amount of damage that was done in the traditional lawn is now kind of negligent, we’re losing that high input level. But it’s still not really building a healthy ecosystem. It’s not really doing much specifically. And that’s where the next level really kicks in.

And that’s when you start working with the native species. And there’s a lot of different ways to do this, but I think the next transition would be to look at a native lawn alternative. So we’re not yet thinking about just a new forest or a meadow or some new garden. We’re actually thinking, I want a lawn of some sort that’s made out of native species.

And there’s some real standouts that work for this. My personal favorite has got to be the wild strawberries [above, in flower]. I love the idea of a strawberry lawn. I actually loved the idea of a strawberry lawn before I realized that we had a native strawberry that really works well for this. And the caveat being that the cultivated strawberry, frankly, it’s a lovely plant, but it’s not going to work for lawn purposes.

Our wild strawberry [Fragaria virginiana] has the advantage of being a very vigorous grower and being very abusable. This is a lawn that can be walked on, that can be dug in, that could be manipulated and that can handle no-mowing and no fertilizer and no watering once established.

And the great advantage when you get into the native spectrum is all of a sudden, you’re not only reducing all of those inputs of the previous lawns, but you’re now building an ecosystem. It may not be as rich as a diverse meadow with 40 species. A strawberry lawn is pretty much strawberries. But those strawberries provide a huge amount of habitat, much more than most people realize.

When you start looking at the list of species that provide large amounts of habitat, especially in my area, you realize that strawberries are Number 2 on the list when you’re specifically looking at the herbaceous plants. Goldenrods are top the list, and wild strawberries are number two. They support about 87 different species of Lepidoptera in the New England region. And that’s a very respectable number. That is more butterflies and moths than most plants that we call pollinator plants and put in pollinator gardens.

And it’s got the advantage of them feeding us, and other wildlife as well, with the strawberries that come later in the season. And who doesn’t love a strawberry.

Margaret: And so that’s like a groundcover. We say “native lawn,” but it’s not going to be exactly like our grass. This is a slightly different thing. But it’s low in a groundcover way. Any other plants that you’re experimenting with or particularly like?

Dan: Sure. Yeah. I mean, if you want a lawn that still looks more like a traditional lawn, as in a grass-like plant, my next go to is a plant called Pennsylvania sedge, it’s Carex pensylvanica [above]. This is a native sedge. It’s a grass relative. To my eye, and frankly everyone else’s eye, it just looks like a grass.

So if you’ve got the interest in some form of a native lawn, but still want it to look like that lawn, this is a really good option for you. And it’s got some similarities with wild strawberry. It’s not as fast of a spreader. So it’ll take an extra season to really fill in. But it spreads fast enough where it’ll do the job in usually about three seasons. And it also does not need any regular watering, fertilizing or mowing. Once you get it established, you can pretty much just let it be.

A lot of people like to mow this one once during the season, to keep it shorter than the probably 5 to 6 inches it’ll top out at. And the nice thing about it is it puts all of its growth in during the spring and into early summer. So if you hit this with the mower, I’m going to say sometime around mid-June, then it’ll stay that mowed height for the rest of the season. And so you can even keep it short with still a minimal amount of mowing.

Margaret: O.K. So, we could swap out, we could get rid of–again, we have to zero out the lawn to do this, because I assume this is not stuff I can do from seed, like those other eco-lawn suggestions you had, but that I still have to have a blank canvas. And then I’m using what? Plugs, landscape plugs, little small plants that I have to order to do this, and it’s going to take longer for them to grow in?

Dan: Yes, that is I think one of the current at least, I hope this changes, but it’s one of the current disadvantages of these natives that we’re discussing over the previous gradient in the non-natives. So with our natives, you can’t go to the hardware store and buy a big bag of Carex pensylvanica seed. That’s not available. And even if it were available, it probably wouldn’t work very well. It’s going to be a tough one to grow from seed.

So you’re looking to pick up plugs, or if you’re lucky enough to be around a place that can do bare-root divisions, you can purchase bare-root divisions.

But it also leads me to my next recommendation, which you’ve already alluded to, which is in many cases, trying to go whole hog and kill your entire lawn and start a whole new, say, Carex or strawberry lawn from scratch is a lot of work.

And the nice thing about these plants, specifically the Carex and the Fragaria that we’re talking about is these are colonizing plants. They’re rhizomatous spreaders. So if you start with say a small section and get that established, we’ll say with wild strawberries, the next season, when that area is established, you can then go zero out a new section of your lawn, and just pull some plants out of that previous section, move it over to the new section. The previous one will fill in. And the new one will start to fill in as well. And you can leapfrog along.

And this allows you to tackle things on a spot-by-spot-spot basis. It means that the job is much less daunting than trying to do the whole lawn at once. And it’s a great way to save some money and save some time. Buying plugs is always going to be more expensive than buying a bag of seed. It’s going to take more work. It’s going to take more time. And it’s going to take more cash. And so being able to leapfrog is a really nice way to go about this.

Margaret: Right. So, to prepare, and I know in the “New York Times story,” you discussed how you and your wife at your relatively new home project, you’re trying to zero out some vinca, not just some lawn but some vinca that came with the place. And you’re smothering it. And I know, as I’ve just mentioned a few times, smothering is your favorite preparatory method, as opposed to chemical herbicides or whatever. Just tell us quickly, what is that, if I want to make a small area of Pennsylvania sedge or Fragaria virginiana, if I want to do that, how do I get the prep done?

Dan: Sure. So what I do is if I’ve got an area that’s got tall plants, tall lawn, whatever, I’m going to get in there with the mower, and I’m going to mow it all down. And in this case, I mow as low as I possibly can, and I leave all that cut material right in place.

Then I cover all of that over with some cardboard. And you can go with just the random pieces of boxes and stuff that you pick up from the local hardware store, or wherever. Or if you want to streamline and don’t mind spending a little money, you can go purchase a product–the one that I get locally is called Ram Board. I know there’s a lot of other ones out there. And what it is a roll of cardboard that usually painters use to protect floor surfaces when they’re painting, say, ceilings or walls. And this is a fully biodegradable product that I will lay down in this now-mowed area. And then I’ll start covering it over with stuff. You notice the specificity there.

Margaret: Yes. Very. “Stuff.” [Laughter.]

Dan: Use whatever you’ve got available to you.

Margaret: Organic material.

Dan: Organic material. Often for me, it’s a combination of wood chips and compost. That’s what I have available. It works very well. But I know folks who have used leaf material, whether it be shredded or unshredded. In this case, you can use compost.

The only thing I really wouldn’t recommend is your typical bark mulch. It’s probably not going to work well for this. But the nice thing is that wood chips are frankly pretty easy to get your hands on. They tend to be pretty cheap. And they’re a lot easier to move than compost. Weight-wise, they’re much easier to work with. So wood chips is usually my recommended go-to for most people.

Margaret: O.K. And so you’re putting this on top of the barrier, the cardboard or the Ram Board, and this becomes then … Are you then right away plugging in your baby plants or what?

Dan: Yep. This is where you get to decide how you want to do it for yourself. In most cases, yes, I tend to plug right in. And in that case, I like to make sure that my topping layer, the wood-chip layer, is going to have, say, some compost mixed in. Or more often than not, if available, I’ll even throw a little layer of topsoil on top of my wood chips afterwards.

And I’ll plant in my baby wild strawberries. And by the time those fill into that topsoil and start rooting into the wood chips below, the cardboard underneath has started to decompose, the grass underneath has been smothered. And they can then just root down and kind of take off.

And you’ll find often that that first season, they fill in slowly, but they don’t do a ton just yet. And then by the next season, all of a sudden they take off. And what you’re seeing happening is you’re seeing them getting past that now-decomposed cardboard layer, and really rooting into the soil underneath.

The other option is to simply lay down your wood chips and leave it be. If you, say, do this in the spring, then you’re usually ready to plant in the fall. Or you can do this in the fall and plant the following spring, and give yourself time to work on this.

Margaret: All right. And so I have a million other questions, of course. One of the other things we can do when we’re in that first tier, with mowing at a higher height and so forth, and watering less and not using chemicals, we can also have more “weed” tolerance. And I’m using weeds in quotes because there’s lots of great things that may start to come in and flower. So we can have more tolerance of those. I just wanted to make sure we pointed that out. [Above, self-heal or Prunella vulgaris.]

And then I just wanted to take the last couple of minutes to ask about Norcross, because that’s what you’re doing. And I know you’re very excited about it. And I think people can come and visit. You have trails and all kinds of things going on, too, yes?

Dan: Oh yes. Please come visit us at Norcross. So we are centered in Wales, Massachusetts. We’ve got just over 8,000 acres to our name over the whole scale, including a 75-acre section that is open to the public six days a week, Monday through Saturday. [A trail at Norcross; Norcross Wildlife Foundation photo.]

And if you come on in, you’ll see a number of historic lawns on site that are all getting assessed right now in terms of, why are they there? What are they doing for us? What could or should they be? And each one of those is getting a little bit of a different treatment. You’ll see some strawberry lawns, you’ll see some self-heal lawns, Prunella vulgaris, that we don’t have time to talk about today.

Margaret: Self-heal, I love it. Yes.

Dan: Some Carex. And then you’ll see other areas that are still to one extent or another lawn with violets and bluets and various other lawn weeds that I frankly think are much nicer than lawns anyway, that are encouraged in these areas.

And then the full spectrum is other areas where the lawn is getting turned into something that really isn’t lawn anymore. Whether it become a meadow or a forest or you name. Sometimes the lawn doesn’t actually need to be a lawn. And then your options are really open.

Margaret: So you’re really pondering on a much larger scale, but the same thinking you’re applying that we were just talking about, these gradients of ecology, and what’s it meant to be? And what can I afford to do? And what’s manageable? And all of these factors on a larger scale there at Norcross.

Dan: Yes, exactly. We’ve got the, I guess, advantage and disadvantage of having a lot of lawn spaces to consider and work with. So, we’ve got the ability to really do a little bit of everything over there.

For most folks, you’ve got your front lawn and you can pick one of these and go with it. And it works well for you. But we’ve got a lot to work with. And we’ve also got a lot of old pastures, which are not quite the same as a lawn, but there’s a lot of similarities. And so the thinking is very similar. [Above, at Norcross; photo from Norcross Wildlife Foundation.]

Margaret: Well, it’s very exciting. And Dan Wilder, I hope that we’ll talk again soon. And I appreciate your helping me with that “New York Times” garden column. It has even more information about some of these particular aspects. But thank you. And like I said, I hope we’ll talk again soon.

Dan: Margaret, thank you so much. It’s always a pleasure to talk to you. I love watching the work that you do. And yes, let’s do this again, 10, 20, 30 more times. I’m happy to talk anytime.

  1. Alissa says:

    My small lawn is almost entirely covered with thick moss, and I am planning to use a selective herbicide to kill the grass and feature the moss instead. Moss is such a beautiful alternative!

    1. Mary says:

      Small wildflowers interspersed with moss is a great option– part of my ‘lawn’ is just that. The wildflowers popped up on their own.

      1. Mary says:

        Margaret: how do you pick such timely topics every week! A front garden needs a ground cover that the wild strawberries should work in. Our front yard is two-thirds mulch. No grass, only mulch and some shrubs and gardens. This year we took out three-quarters of the grass in the backyard and replaced with gardens and crusher fine. There is just enough grass for the dogs to lay in and gardens for me. The trees provide shade so the gravel is not hot. Loved this podcast (as usual).

        1. Pollyalida says:

          I have been smothering large swaths of my lawn since we bought this house 7 years ago. We live in a very chemical lawn culture community. Thank goodness there aren’t any rules about lawn care though. I love the idea of wild strawberries and will plan to edge out even more lawn this way next spring, or sooner.

          Wondering what other low growers would mix well and not out compete the strawberries?

  2. Kate says:

    I planted wild strawberry (where I garden in Central Arkansas) in 2016, and I would actively discourage suburban home owners (in these parts) from planting it as a lawn substitute. In Central Arkansas this is extremely aggressive (and difficult to contain or remove once established); it’s also a bit of a gangly awkward plant unless it’s periodically trimmed or mowed; and it can smother other low growing plants (like sedges, phloxes, etc.) If you had a lot of land you wanted to improve for wildlife, a place where this didn’t need to look neat or tidy and could go all over the place, it could be a really good option. (It’s extremely tough and can take poor soils with little to no additional babying).

    Central Arkansas is outside the area where most eco lawn mixes work well… and we can get too much water for things marketed in Texas. If you have very good drainage, you may be able to pull off Habiturf (from LBJ). Sedges can be a good option (particularly if you have part shade/shade). In full sun – you can try Carex texensis or Carex retroflexa (if you can find them).

  3. Masha says:

    I planted a strawberry lawn before it was cool and I love it. The wild strawberry portion actually planted itself, and we added 6 varieties of cultivated strawberries- 3 Alpines and 3 larger types. I’m confused about why Dan thinks cultivated strawberries won’t work well for this purpose. At least here (Hudson Valley NY) they work fine.

  4. Melinda McCall says:

    Interesting! I have been encouraging wild strawberry to spread under a blueberry patch that was initially deweeded by smothering with cardboard and woodchips. All sorts of wildflowers have appeared, but the main plant is Potentilla/cinquefoil, which is so much like the strawberry except for yellow flowers, and of course no berries for the critters. They are lovely together.

  5. When I lived out in the East Bay of San Francisco, the first thing I did was rip out the “lawn” and turn it into succulents, fruiting trees, and other low-water, drought-tolerant species. No more lawn to cut/water or maintain. I am attempting to cut down parts of my lawn here in my western N.C. home as well. Some I will leave for our dog and for our use, but other areas will be easier just to leave as our “weedy” lawn. I am planning to have my neighbor help me (with his farm tractor) till a section of the lawn so that I can seed it with wild flowers sometime this summer or early fall. Much of the existing lawn has been turned into flower beds, orchard, veggie garden, chicken coop and pen, and more flower beds are planned over time so that there is less and less to mow. That is the plan and the dream! Great ideas in the article. Thanks for spreading the word!

  6. Wendy Cleaver says:

    a more ecological approach to lawn, with dan wilder

    I so wish I could have read this about 6 weeks ago! I decided to let my grass grow, and now I am going to have to mow it all down and start afresh, (husband not too happy, he didn’t want me to do it in the first place!). Anyhow, he is willing to look at this article and plan our next move toward a more ecological garden!
    Thanks Margaret for sharing this with us, especially me!

    All will be well,

  7. Doreen White-Hatke says:

    When I purchased my home almost 2 years ago – it was very overgrown with poison Ivy, Virginia creeper , rose of Sharon , vinca, pachysandra, trumpet vine, summer sweet clematis – just a tangle of greenery- no chemicals or pesticides- just spent so much times pulling out vines and then used wood chips 4-5 inches thick to cover ground – working hard to convert it mostly native – decreasing the “ lawn “ area , planting native trees, and finding native plants for shade and full sun ~ bird houses , feeders and water bring lots of birds and insects – very glad to hear it’s a popular idea and looking forward to seeing less sterile emerald green lawns !

  8. MB Whitcomb says:

    I am a designer [with a Facebook group], and was surprised that there was not a discussion of analyzing the “what, where, when, how, and why” of lawns. It is extremely important to consider what lawns are (or are not) used for when making these decisions. Map out what your needs are, and then how much of your lawn is NOT used for any of those needs. You definitely need a way to get from place to place, and most of us are (inexplicably) terrified of “the bush”, so paths. If you have an infant or a puppy, you need a safe place without toxic plants (until you teach them not to eat them). If you have a teen that needs a place to practice football, does it really need to happen at home? Or is there a sterile community “lawn” within walking distance? There need to be what I call “landing pads”. Places where a picnic table might be, a place where people greet or send off visitors, or just a seat by a brook, for example. These are the only place where short plants might be necessary. The “where” is where you live…if you live in forest fire prone or heavily tick infested areas, these are powerful forces that can impact you in dramatic ways. The “when” may determine the frequency of care. Does walking around quietly with a pair of shears a few times a year removing invasive species before they seed seem like more fun than driving a polluting machine that annoys everyone in the neighborhood? To me it does…I see the developments…new species arrive, enjoy the exercise, and love being outside. In one project we do this and mow only paths, and one-third of it a year. The return of the birds has been awesome, but you gotta learn your plants!

    On “how”, this is the basis of the program and was very interesting, given I am year 4 into a “can I make my lawn area native” project. I did not do a full kill on the lawn, and wish I had (but need to try one to be sure). I decided that the native grasses and forbs we found in meadows when I was a child where what I was after and that the genetic stock of what had been local here all along and taken 12,000 years to evolve was important.

    What I have learned is that lawn grasses, and clover are complete enemies of our native species (hair grasses that form clumps). The white clover, in the last 10 years has moved into many ecological niches, along with dandelions, hairy bittercress, and other European weeds that people have been encouraged to spread by “blow the dandelions” (which are really about 30 species with similar flowers some, like the fall dandelion (Scorzoneroides autumnalis), and hawkweeds (Hieracium and Pilosella) and “No Mow May” (both ideas were developed in Europe and don’t necessarily help us here, but DO encourage European native plants that are here with zero predators to keep them in check…you become the only predator. These plants completely obliterate the native grasses, and have seeds easily carried on shoes and tires. Next time you walk your favorite wild trail, look at the plants along the trail…they are European lawn weeds…and most have short generation times meaning they are not staying on the trail. Fields of dandelions were not “planted”…they took over. SO please, skip the clover step…make sure you are sourcing native plants. Ernst conservation seeds has a great catalogue that they ought to charge $10.00 for, as it looks at all the things that can go wrong, seed mixes for different scenarios, and with my few projects under my belt, can see they are the voice of experience.

    In my battle to protect the hair grasses (neat little ferns, mosses, rushes, and sedges) I have learned how many birds use the fine bladeless grasses to build nests, how it grows hand-in-hand with mosses that make it a lovely soft and cool place to sit, how it insulates the ground in winter allowing insects a place to be, how it often grows in association with choice mushrooms and wildflowers like blue eyed grasses, violets, the above mentioned wild strawberry, herb robert, small asters, etc. LOTs of insects use it…for cocoons, to eat, to hunt. Amphibians love the 1′ height (2.5′ if allowed to seed).

    I spend increasing amounts of time defending natural areas from clovers…it is a very “permanent” plant and hard to get rid of…it does NOT play with others and only blooms once a year for a short time…then it seeds everywhere. We do not understand the many ways evolved wildlife uses evolved plants…please seek native plant answers. Eliminate the non-native weeds, and the round-up resistant “golf course” lawn grasses that are designed to squeeze everything out and spread by stolons…that seed and then do that in more natural areas. When Agrostis stolonifera arrived here, it basically has acted like green wildfire, not just covering the surface, but changing the soil structure (along with the clovers and hawkweeds) meaning I see more and more areas where native grasses etc. can no longer compete…in their own homes.

    The Anthropocene is about our carelessness/selfishness in our back yards as much as industry, pesticides, etc. It is about not understanding habitat needs and transforming everything completely so we won’t get our feet wet with dew in the morning, or be startled by a bug, frog, or snake? I can tell you the joy of having “life” return has been worth every bit of the effort…and I have learned so much.

    One more tip…if you are going to “go native plants”, research how to limit/restrict lighting at night…this turns the evolved life of the world on its head because the moon is the only natural light at night and creating “mini moons” everywhere where fascinated/confused moths (12, 500 species or so in N. America) go do beat themselves to death rather than mate, meaning there will be little food for nesting birds. As a general population we need to start understanding these things…because the longer we wait to get involved and start “putting back” what the rest of the world needs, the harder it will be.

      Thank you for sharing your experience and comments. Your suggestions and this podcast will guide me closer to the results I am trying to achieve.

      This is really great information and I’m so glad you mentioned the information on clovers, as I could never find where clovers were native. I have been planting natives to GA for the last 15 yrs of living in our house as it was a full blank slate. It’s more shade than sun but I have reduced the lawn by just planting more native shrubs and low ground covers. I think if people have large lawns, a great way to reduce it is making planting beds and adding natives, shrubs or sedges, or ground covers. It’s worked for me and I love the look of swaths of plants over large “lawn type” areas. I’m going to start adding wild strawberries and other natives to rewind the grass.

    A good source for lawn alternatives in the Pacific NW is “Fleur de Lawn” I think based out of Portland, OR.

    I like these ideas in the podcast, but the Carex especially will be enticing to the bazillions of rabbits that have invaded whole communities where I live., a suburban area. Not enough coyotes here.

    What a lovely idea! I have no lawn, but nothing organized, either, having been a farm. There are dozens, maybe hundreds, of volunteers for me to learn about and decide whether to encourage. My current favorite is white clover.

  11. Karen says:

    Great, great ideas for a home lawn but who has worked with a Condo Association to convert a few on the board to think less lawn and more ground cover? Such an uphill battle in our Ocean View, DE condo development. I mean they still do HARD PRUNING when and if they feel like it with no regard to the shrub’s needs! Any links or advise I heartily welcome as I am on the Landscape Committee representing the natural way of gardening. Best to you-Karen Young

    Hi Margret,
    I dont see any information on where to get Fragaria virginiana. Is it posted somewhere and I’m not seeing it?

    Thanks Kevin

      Nurseries that sell small native plants like Prairie Moon Nursery and Prairie Nursery usually offer it.

    Letting our lawn go wild and we discovered morels growing in it. And every species of native violet in our region. It’s a beautiful thing.
