I wouldn’t find that many earthworms at work in my own grassy meadow. The last glacier, which receded about 12,000 years ago from the northern parts of the US, including here in the Hudson Valley, wiped out all the earthworms. Darwin’s meadow was spared because glaciation didn’t reach as far south as where Darwin’s home eventually stood.
Not that there aren’t now any earthworms here. Mostly, these are non-native species that arrived over the past couple of hundred years and continue to arrive as fishing bait, ship ballast and in soil clinging to the roots of transported plants. Some native earthworms may also have made it up here from New Jersey – not many, though, with their estimated top travel speed of less than six yards per year.
These non-native earthworms are of concern because of the rapidity with which they gobble up organic matter. Their voracious appetites threaten the mountain laurels, rhododendrons and blueberries that thrive in the organic matter – the leafy mulch – that blankets the forest floors in our nearby Catskill Mountains and Shawangunk Ridge.
Those invasive species could effect a change in the landscape we view as we drive along mountain roads and hike the trails.
Back to my meadow, which I have also spent a lot of time observing – but from a standing position, usually with a scythe.
Most years the meadow receives a once-a-year mowing, usually in late autumn, with a tractor. (Early on, I mowed it all summer long with a scythe, but the rich soil encouraged lush growth that resulted in tennis elbow. I still scythe parts of the meadow, in moderation.) That once-a-year mowing is meant to forestall the encroachment of woody plants. In this part of the world, open land typically reverts to forest.
At its best, my meadow presents a lush sea of green that contrasts nicely with the close-cropped areas of lawn near my home. A sinuous path mowed through the meadow, tracing out a different route each season, invites walking through it for more intimate exploration. (I refer to this as “Lawn Nouveau” in the grass-mowing chapter of my book, The Pruning Book.)
Through summer, pale pink milkweed blossoms dot the meadow. Come late summer, purple flowers of beebalm cap the sea of green grass like ocean whitecaps. And then, later and on into autumn, various species of yellow goldenrod bloom in succession. In the cool of the morning, dew and morning sunlight bring sparkle to the show.
A couple of seasons ago I noticed that beebalm and goldenrod were getting increasingly sparse, as were the grasses. Each year increasing amounts of multiflora rose, wild blackberries, poison ivy, even an occasional staghorn sumac were homing in, paving the way to a forest.
Last summer I decided to tip the balance back to meadow. My plan was simple: All I did was mow the field regularly to lawn height. Grasses, which are monocotyledonous plants with their growing point just below ground height, are pretty much the only plants that tolerate regular mowing (or, in the case of prairies, burning). Mow, and grass will come.
This year, meadow grasses are already growing thickly and a couple of feet high. Looking closely, I see very little poison ivy and friends. I will be interested whether or not beebalm and goldenrod appear onstage later, in summer. Another season or two may be needed before they make their appearance.
Our forest flora are dynamic. The nearby mountain laurels, rhododendrons and blueberries, meadows – all landscapes, in fact – are not forever, even without human encroachment. I’m not trying to maintain my meadow in a romanticized primordial state; I just like the look of the grasses, beebalm and goldenrods.
The meadow also has a practical side. My scything provides hay for compost (along with some horse manure, a waste product of a local stable) and mulch. Taking the hay from limited and different areas each season allows time for the soil to regenerate itself.
Readers of this paper may have noticed the absence of my gardening column here over the past few months. Well, I’m still gardening.
After 35 years, I am no longer writing weekly for Ulster Publishing. It’s been great. I’ve enjoyed reader feedback, and the writing provided the experience and confidence to segue from working as an agricultural scientist for Cornell to going on to write for other media outlets and authoring a number of books.
I haven’t given up writing to share what’s going on in my garden and ideas for what you might do or observe in your own backyards. I will continue to write an occasional Almanac Weekly column and contribute to Ulster Publishing’s special sections. For a more frequent dose of my garden writing, turn to my weekly blog posts at www.leereich.com/blog.
Here’s something from me and my garden for this week. Keep an eye out for more. Thanks for reading.
