There are many reasons for a having a lawn. First, it’s the norm. Almost anyone with a house has one and no homeowner in their right mind is going to complain about it. Second, a monoculture of mowed fescue looks great. To most people. And last but by no means least, it’s the easiest kind of landscape in a neighborhood to care for. Just mow it. Get a tractor if it’s too much work. Nothing to think about. Just mow and get out the leaf blower or weed wacker if necessary. Weeds such as clover, ground ivy, crabgrass and Bermudagrass don’t matter so much because when mowed and mixed in with some fescue, can pass for lawn. At least in my neighborhood. With something so easy and acceptable, why would anyone do anything different? It’s the simple truth because it’s so simple. Let’s face it, getting into the nature scene isn’t exactly cut and dry.
Books and experts in ecological design tell us to plant native plants because it’s great for wildlife but if you’ve ever been to a native plant sale you will find those native plants when purchased in any great abundance begin to cost a lot. It’s hard enough to deal with removing a lawn then to have to figure how to replace it with native plants without mortgaging off your house.
I’m not going to go into why I just spent so much time building up my introduction to a book I just finished reading because the name pretty much sums it up. Written by Larry Weaner and Thomas Christopher, Garden Revolution: How Our Landscapes Can Be a Source of Environmental Change is about exactly that. Unfortunately, the answer to why we would want to replace our lawns might actually be simpler than the process of doing it. Why? Because it is a process that takes thought. It’s not that it necessarily takes more time or labor. Well ok, maybe it does take more of that too. But what it really takes is a change in ourselves and our method of operation.
Larry Weaner is a very gutsy landscape designer who makes a lot of meadows. Huge meadows as in 30 acres or more mostly in places in Pennsylvania where there are a lot of empty old farm fields and people with the cash to turn them into ecological meadows. But does he really make them or are they already there?
Much of the book is about natural communities and how they evolve. He uses an analogy I especially liked about a fallen tree. He was out in the woods one day when he happened to stumble into an area filled with blue lobelia, a native wild flower, and wondered how the flower got to this particular spot in the middle of the forest. After noticing a fallen tree in the spot, he came to the conclusion that when the tree fell, it both disturbed the soil and formed an opening where sunlight came through spurring the wildflower seeds already lying dormant in the soil to germinate. For me this story underlies the essence of the book and suggests a radical concept of landscape design. That is the possibility that not everything in a garden needs to be planted by the gardener. In fact, it goes to the extreme of suggesting in some instances, nothing need be planted by the gardener.
This concept of a managed landscape versus completely contrived is not new. Forest management has been going on for centuries and Native Americans have practiced it for much longer than that. My own parents owned land and spent many a long day just cutting grapevine to help a young forest mature quicker than it would without their intervention. But for landscape design, this concept is probably something new. Either that or it hasn’t been practiced for a long while in this country at least.
Of course a healthy seed bank of ecologically beneficial or desired seeds or seedlings isn’t always the case. In fact, I’m guessing it’s pretty rarely the case. In most cases, there is a monoculture growing on some pretty disturbed, contaminated or heavily fertilized soil. And in these situations, in order to establish a desired plant community there’s got to be some heavy clearing, planting and management going on. And on this topic he goes into some detail. Enough to confuse me with the math and logistics of it. But overall it was some pretty thorough and I found well thought out concepts (I especially like the focus he gives to growing from seed, something I rarely find in landscape books).
While the book covered lots of subjects and details about how to design ecological gardens what made it great for me was it made me think differently about gardening. Books and experts are all good but nature really is the best teacher. This quote by the author’s mentor, ecologist Frank Egler sums it all up pretty well.
“Nature is not more complicated than you think, it is more complicated than you CAN think.”
