Winter Seeding

Our first snowstorm was brewing on top of an inch that had fallen two days prior. Although there was much to do, I paused to get out to the back swale, once wet, now dry, to scatter the seeds I had collected.

The roughly two acre swale, either artificially created by gravel mining just over the property line or an artifact of the terminal moraine on its northern flank, used to dry up each summer, enough so that tree species accustomed to periods of water logged soil could still grow to sixty or seventy feet tall. These trees have now died, the largest within the last three years, because of permanent inundation.

This year, another change had taken place -the swale dried down. The spring tree which drains the area continues to flow and a walk through the swale could still leave you suctioned to its wet bottom, but the hummocky surface is dry, the duckweed a gray mat. With that had come an incredible explosion of canary reed grass, the cool season, hybrid grass created for just this type of environment. In two short months the grass multiplied its square footage by ten and left little room for intervention by this woods gardener.

Canary reed grass or reed canary grass, Phalaris arundinacea, is terribly hard to remove -more so than garlic mustard, buckthorn, and creeping charlie combined -for its wet soil, its nearly impenetrable mat of fibrous roots, its rhizomes and seeds. Although developed for haying wet ground, wild animals do not care for it. Yet here, it is clipped, but I cannot recall whether I clipped it in preparation for some type of management or it has been grazed by deer this late autumn. If it was deer, that would be unusual.

I will not be able to remove the reed grass, nor do I intend to spray glyphosate on it. I've tried plastic tarps, but there are now too many woody obstructions over a region much too large for that. My plan is to seed this open area, ahead of the advancing grass, in hopes of some species gaining a foothold. Only if the pond does return, to its last maximum, will the open water push the mat of grass back to its edges.

If the pond does not return, this wet meadow may have a limited number of species capable of growing alongside canary reed grass. I've seeded blue vervain, Verbena hastata, common milkweed, Asclepias syriaca, swamp milkweed, Asclepias incarnata, various asters and goldenrod, and a bit of big blustem. I had two dozen blue lobelia, Lobelia siphilitica, starts remaining from the late summer planting, roots still alive, that I dropped in the hummocks under the snow. And in late September I planted dozens of Spotted Joe Pye, Eutrochium maculatum, more blue lobelia, and several other species I cannot recall at the moment along the more shaded swale edges where the canary reed grass had yet to overtake.

City House Country House

When I lived in NYC, which has been most of my adult life, there was gardening to talk about. This may have been due to how little gardening was truly going on. There was time for talk, for idle thoughts, for chit chat. There was standing on the corner, taking waves and how you doin', little to the garden footprint but such large human imprint. There were complaints that people could relate to (really, diapers on the hydrangea, again?). Glitter faced prostitutes offering assistance, Russian emigres with effortless tongues, kids who saw onions in tulip bulbs, landlords with teeth to gnash, unskilled laborers who knew how to dance in a garden, familiar weeds, oceans and peas, garlic and sand, and the sticky, salted skin when the onshore turned in for the evening. There were myriad plots across countless yards, tree pits, sidewalk strips, and undeveloped dreams. People have a passion for growing things in the city because the passion is on parade, is persistently evident from the walk to the subway, from overtures to our agrarian past on highrise rooftops to the panacea of the hyper-local, from the artist-led food garden to that curious moment when enthusiasm ran wildly into a business growing food in your backyard. The city a counterpose to the garden, an architecture for the gardening posture, a context that convinces us that a garden is the cure when it is merely a salve.

I now garden in a different context, one that is younger to the white man, but has seen its share of rapaciousness. With enough trees around even I can convince myself that my place is not an island in a sea of suburban plant homogeneity and millions of acres of either corn or soy. The optimist will extend the metaphor to an archipelago, but little more. To garden on the scale of fifteen, even thirty acres is an arrogance, and so me at my most arrogant goes about gardening the woods, weeding the woods, fretting over the rising and falling water levels in various swamps and wetlands, watching opportunistic plants move rapidly into space available, making plans and haphazardly executing them. This is to say nothing of the vegetable growing, the cultivated gardens or lawn and shrubbery that make up much of the country house.

Despite all that is going on, all that there is left to do, I have come to accept that there is not much time to talk about it. Exposition is the garden work of the city house.

In defiance of this conceit, I offer a picture of the country house -its autumnal prairie-ish planting east and north of the studio. Now in its second summer, many new plants have begun to mature. The pollinating and predatory insects love it, although the birds enjoy the much simpler savanna-ish planting on the building's south side. The deer all too much love the woodland planting on the west side of the building, now under revision. 

This week I'm in the middle of expanding the prairie-ish as I restore our one thousand foot gravel driveway, a process that includes digging drainage swales alongside the drive, loose soil slopes covered in burlap, winter seeding and fall planting of woodland natives I'd started last spring, moving boulders to shore up one or two hundred square feet of new cultivated garden space, and a whole hell of a lot of 3/4" minus crushed red limestone spread by myself in a track loader that will then be compacted by Betsy with a vibratory plate.

The Month Spring

The Weather

 

The last spring snow melted in the gardener's lot the night of May 10th. It will now be in the nineties.

The Farm(s)

On the ninth, I had a moment to look on the garlic, strike the weeds with a hoe. Never before have I seen the garlic so small so late.

The effervescence of lambsquarter and thistle is contained with mats of semi-wet straw remaining from last fall.

The Greenhouse

Three rows by five of ear leaved brome, Bromus latiglumis, out front of 4 rows of bottle brush grass, Elymus hystrix, and three rows of silky wild rye, Elymus villosus. An ability or want to grow in the shade is a commonality among these monocotyledonous Poaceae. These will likely be established on the culvert embankment, partially collapsed last fall, once restored.

It takes an especially observant person, and some years of experience, to decipher one seedling's visual cues from another. Identification -what is that? Dicotyledonous plants, with pubescent stems and leaf edges, slightly wavy heart-spade shaped leaves, pale green, growing thickly (indicating small seeds to the planter of seeds). This blindness to leaves and stems, the miniature, and impatience allows many undesirable plants to survive the hoe.  Refining possibility by my seed order leaves only Campanula americana, or Tall Bellflower. When I return from Cedar Creek, the tag will tell how experienced I am.

Blue lobelia, Lobelia siphilitica, whose seeds are only a fraction of a millimeter, have a stellar germination rate. Competition must be the thinning mechanism.  These seedlings are for the northern edge of the great swamp, that two acre depression of drowned trees, duckweed, and fluctuating water levels toward the back of our woods. On that partly shady slope -weedy garlic mustard, thistle, canary reed grass and me. I've got black plastic on part of the water's edge covering canary reed grass, and been hoeing then planting Iris versicolor, spotted joe pye weed, blue vervain, big blue stem grass, and others. The seed bank of garlic mustard and root network of thistle is deep, while canary reed grass forms dense, fibrous mats that are bears to pull, but there is also a surprising amount of diversity in this highly disturbed site at the edge of a former commercial gravel pit.

Ephemerals

Hepatica, Anemone americana, trailside, Cedar Bog Lake trail, May seventh Cedar Creek Ecosystem Science Reserve.

Large flowered bellwort, Uvularia grandiflora, like many ephemerals growing in our woods, had a prolific season. Is this is due to winter weather resembling winters these plants have evolved by? Last year, after yet another overly warm winter, I stumbled upon one, maybe two bellwort. This spring there are possibly dozens of clumps scattered in previously barren understory sites. Our only known patch of trillium, nibbled by the hungry deer this spring, now has peers. A display of randomness that throws off any rational sense of seed distribution and opens us to the potential of seeds storing in ground until conditions are right, to a migration of seeds via ants and mice, and, as is the case with trillium, to the slow process from fruit to flowering plant. A warming climate, should it create a warming winter here, won't be hospitable to these spring ephemerals, more likely favoring the weedy plants that take advantage of disruption and do not have such particular requirements for germination.

Nodding trillium, Trillium cernuum.

 

Gardening The Woods

There may have been a moment (or two) when I looked at my field of garlic, its plethora of weeds, its need for harvest, or even the bare soil in need of turning, and felt overwhelmed. Gardening the woods doesn't meet that level, it exceeds it. It is farm work spread over a decade -or more. In spring I garden the garlic mustard and in fall, I start on the buckthorn.

I refer to this process as gardening because restoration is a fallacy. There will be no restoration, only limited choices, however informed by research and good intentions. My work amounts to weeding, seeding, planting, observing and acting like any gardener would. My preference for plants native to this biome is practical and aesthetic. Practical because they are survivors that, once established, do not require my care. Aesthetic because they become part of the whole and offer surprises. I like the unexpected.



The oldest buckthorn trees line the edges of the sunny, wetland clearings where birds congregate and eat from a quantity of berries. Under roost trees, seed density can easily reach several hundred per square meter and sapling density averages 100 per square meter. As the birds move through the woods, so do their droppings. Consider the image, above, a map of bird roost sites, droppings turned young saplings in a green stream flowing north.

This panorama shows the stream of saplings progressing northward from the great wetland. It follows the bird flight pattern, but also the soil moisture of a seasonally flooded depression that in turn takes out trees that enables sunlight to hit the forest floor, increasing germination and growth. Yes, the buckthorn does grow up the slopes, perpendicular to the stream, but sporadically compared to the edges of the vernal pooling. However, in time and without my gardening, the whole of the area will become a thicket as these saplings mature and produce berries to seed the slopes.

It is early November, when all native deciduous plants have dropped their leaves in preparation for winter. This makes it simple to identify the greenery above as 100 percent buckthorn. On this southern slope, descending to the great wetland, the age diversity of buckthorn increases dramatically, topping out at mature, multi-stemmed, 25 foot trees at the wetland edge. Why such an incredible age difference merely 40 feet away? It may be because our woods have seen several mature oak trees come down over the last twenty five years, opening light to the forest floor and eliminating a thick cover of oak leaves that studies suggest limit buckthorn seed germination. More sun has broken the lowland canopy as our once considerable bank of green, black, and white ash trees die off due to emerald ash borer spreading since 2002. Dead or alive, felled trees take out additional trees as they come down, further enhancing the light hitting the forest floor.

An impenetrable thicket wasn't on this slope ten years ago. In summer, 2012 a thunderstorm took out two large oaks that were, maybe, 150 years old each. In five years this is what has become of the buckthorn seed bank.

The reason for Rhamnus cathartica's success? It outcompetes in photosynthesis, carbon gain, shade tolerance, light tolerance, moisture tolerance, earliest leaf out, latest leaf senescence, seed production, female to male ratios, age to fertility, germination rates, and mortality. It also germinates well in the particularly barren late summer soils of our mature forests, a by product of non native earthworms and growing deer populations. It's leaves are higher in nitrogen, decompose faster, and are eaten by the worms first, quickly cycling nutrients under buckthorn stands. It has no issue with anthropogenic disturbance. This plant does not create thickets in its native ranges, but it does in the midwest where it responds to fertile, calcium rich, mineral soils. As plants go, buckthorn has a lot going in its favor.

So why go after it? Why commit so much time and labor to removing it (no easy task)? Again, I liken it to the garden. Imagine your garden was only hydrangea, everywhere hydrangea, but this hydrangea never flowered and had thorns. Who would want a garden like that?
