At Home

It was back in July when we spotted the first giant puffball of the season. This was early -too early to our senses. By August's middle the water table had been coming back up, not quite draining after a moderate rainfall. The temperatures had descended to the mid to high seventies and steadily declined into the mid to high sixties by the last week of August and first of September. The trees prepared themselves, the monarchs passed through, the squirrels returned to the lawn, and the rains fell. Our autumn is upon us, and has been since mid August. I have casually mentioned to some that the season had changed, before the Minnesota State Fair -typically a late summer festival. For my observation I received a squint and pursed lips, huh blended into hmm.

To perceive the early arrival of autumn is nothing special. To read the language of our environment and to understand its meaning, in the Western mind, is like understanding Latin. Most will see an archaic text, pass over it, and only occasionally fathoming the root of some current verbiage. Millions of years of evolving, hundreds of thousands of years within this epoch of variable, yet recognizable, climate and species and still we have lost the ability to be at home in the world. I write 'at home' to indicate that set of cues that are so familiar as to become understood inconspicuously.

Our trip to Yellowstone National Park, the primary stimulus for these thoughts, offered some very unfamiliar cues. If you haven't been, go. The park is massive, often taking several hours to get from one site to your lodging. There are bison, and more worrying -grizzly bears. You are walking on a volcano, something difficult to dislodge from your steaming, sulfur-scented consciousness.

Every season I have five, ten, maybe twenty projects to accomplish during the warm season. I typically finish three, especially when the warm season lasts only three months. This year's major project was to complete the renovation of the front lawn-vegetable garden. Above, eggplants, peppers, and cucumbers.

The far left raised bed was refurbished as it had been made from scrap decking, then a new ten foot bed was built and installed, and the remaining two beds moved from last year's location. The framing and mulching was accomplished in early June and then I moved on to other projects.

After our return from Yellowstone I set about laying the sod. We chose sod to cover the area previously covered in black plastic laid to smother creeping charlie. Sod is outside of my experience, and I messed up. When laying sod it is best to have prepped the ground ahead of time, it's best to get it unrolled in a day or two. I had to stretch it over four days and nearly composted the sod on its pallet because I hadn't the time to prepare the soil, pull the volunteer tomatoes (what was I thinking?), or deal with the unknown habits of sedge that had grown where the beds had stood the year before. 

It was only continual rain storms and the early autumn temperatures that spared me the near-total loss of live grass. I credit this for its return from tawny mush to lively green, albeit a few patches of dead remain. Although I've been spared the shame of spending a small fortune on sod and then killing it, the lack of soil preparation will undoubtedly reduce the benefits of sod over seed in the long run.


We've had a good year for brassica, getting two months of broccoli from under twelve square feet. BT worked well on the cabbage worms after I removed the floating cover fabric. I've also observed that deer do not seem to care for kale when there is so much else to eat in your garden.



My July planting of green beans were trimmed quite well by the four-legged pruning crew. But, they came back and I now have a steady supply to snack on in between mosquito raids. Unlike a national park (the "wilderness"), our place is home to us and many other creatures. Living with them feels much more natural than any wilderness experience I've had.

It May Be July



Just finished putting together the new vegetable beds. Four raised beds, each about 12 inches tall. The herb bed was the first, back near the greenhouse. Then the two nearer, each already around for a couple of seasons, but moved yearly. After attempting to grow vegetables plunked in the middle of the  lawn, I soon realized that it wasn’t going to work.  We didn’t want to mow around sprawling vines and the shade allowed aggressive creeping charlie to truly creep.

I concocted this new scheme, very much wood chipped, framed by cedar ripped on the table saw and spiked with rebar to hold it in place. Once dreamed up, I set about building the final raised bed. The lawn will be rebuilt on three sides, plenty far from the beds.


Tomatoes are supported by two zinc-coated irrigation pipes plugged into 5/4 cedar deck boards also ripped on the table saw. String is attached to the leading vines and wound over the pipe. The tension created with this type of system keeps tomato vines from ever flopping over. I’ve never applied this system before, mostly due to laziness and lack of necessity. It’s neat -I like that, but it requires a willingness to reduce the number of tomato producing leaders. We won’t need so many as all our other tomato starts are planted in the neighbor’s garden, just downhill from the garlic. 



This was the same, June 21, not much more than three weeks ago.

A Prelude to the Understory



After two full seasons of intensive looking, I still find unfamiliar plants. Sometimes I photograph, sometimes I pluck a specimen (depends on the quantity). A fraction of those make it to the concentrated search for identification. Of course, identifying a plant isn't always remembering it, and that takes something more: a drawing perhaps, a meal, maybe, or some other triangulation of anchoring interactions that commits a new identity to memory.


Mosquitoes in the dark and damp woods can make any phone photographer's shot a blur. When in doubt and plenty, pluck a branch, preferably in flower. If you can get to it quickly, bring the pluckling to your computer. If you can't, photograph it on the hood of a car, and get to it later. Here, a plant that beguiled me through the garlic mustard harvest. I now know it as Canadian Wood Nettle, Laportea canadensis.



Above, a plant that must've been easier to miss across prior years in a dark woods. Now, freed from other obsessions, I saw it everywhere, understory. It's form is suggestive of both invasive species and Eastern Forest native, a counter distinction to the many invasive forbs that to a degree appear "out of place" in our woods. Awareness of such differences is both a product of experience within the Eastern Forest, but also a diminished plant blindness.

This "new" plant was challenging due to its small white or maybe green-yellow flowers, its casual umbell, and my age-induced farsightedness. The umbell, trifoliated habit, and seed tipped identification toward an anxiety-producing, naturalized reversion of Aegopodium podagraria, goutweed or bishop's weed to you and me. We have two large colonies of goutweed on the southern slope, but something wasn't quite right about this ID. I had to dig deeper. I had to zoom closely on the seeds, had to engage with leaf sheaths, and most importantly, I had to learn to see double serrated leaves. Those cues in hand I was able to find this plant's true identity: Canadian Honewort, Cryptotaenia canadensis. Why this subtle plant has a name composed of "hidden" and "tapeworm," I do not want to discover.



Sedges fill a minor savanna between the road to the east and the house to the west, the little wetland and great wetland bounding it on the north and south sides. Oaks used to dominate this dry mound, but basswood and maple are encroaching.



Oaks die or fall in storm winds, as this large one had two summers back. The oaks, when dominant, create a canopy pierced by sunlight, an environment the sugar maples do not provide. The understory is complex; already colonized by sedge, ephemerals, and a lower dose of garlic mustard than is typical in more moist, down-slope locations. Maybe the clearing's relative isolation has allowed more native species to proliferate than in other tree-fall clearings nearer the house and adjacent, cultivated properties.



I was overjoyed to spot a strongly growing specimen of poke milkweed, Asclepias exaltata, a foot from the fallen oak. I tray-planted 50 seeds of this less common milkweed last year. Only six sprouted, then five took faint hold along the edge of our septic field; five that have since been moved to the new, mostly shady clearing behind the studio. I've decided that poke is not as easily grown as swamp or common milkweed, but it is the only milkweed common to shadier, woodland locations, and I'd like to have some growing out there. Maybe I will try again, next year.

Although I intended to keep the mound of fallen oak and poke milkweed clear, time and garlic mustard always seem to get away from me. Askance of plans, among mosquitoes excited by a coming storm, a moment was wedged to clear any observable, green seedpod-bearing garlic mustard. As the lightning became daylight visible and thunder claps louder, I decided to discontinue what is always an ever expanding circumference of mustard weeding. Today, nearly all remaining second year garlic mustard is yellow fading into beige. Seeds by the thousands are lined up for distribution on sites already occupied by thousands more. If a rift in time should open, I will get into the woods, shod in mosquito net cap, to clip and bag the drying stems from areas newly colonized.

I spend a fair amount of time identifying plants: weeds, natives, and cultivated for myself as well as others. Texts roll in with pictures of pokeweed or Fallopia japonica, multiflora rose and daylily. Most pictured plants are easy to identify because most are coming from yards carved out of the Eastern Forest. In them are cultivated plants or common weed species of Eurasian provenance. In making yards -clearings designed to lessen our work (ha!), lower our exposure to pests, and provide a platform for leisure, we offer opportunity to ambitious plants.

In the process of putting up our studio building, I created about two thousand square feet of opportunity. The area is now covered in subgrade clay over topsoil because when we dig, what is beneath ends up on top. Many desirable plants won't flourish in this subgrade soil, but the adventitious do. Given my positive experience growing native milkweed, I ventured to grow several native plants for the sunnier part of our studio clearing before the weeds take hold.



I imagined a medium height grass and forb savanna underneath the tall basswood on the south side of the building and under the red oak on the north east corner. I winter seeded Prairie Moon's short grass inexpensive seed mix and savanna enhancement mix, both of which had some species from their exposed clay mix. Sowing seeds felt like leaving too much to chance, so I also stratified hundreds of individual species seeds through winter, then cell tray planted them in April. But, an unexpected hot greenhouse day in early May boiled many of my seeds laying patiently under their moisture-preserving cellophane wrap. Most were lost, although some did sprout near the cooler edges, and those are now large enough to be potted up.



Growing native plants from seed is not always easy. Cultivated plants have been bred and selected for viability, commercial or otherwise. Natives, however, maintain their original, sometimes fussy seed-sprouting needs. Multiply cold, heat, or cold and heat by time, then add light or darkness, subtract or add moisture, and you may have a formula that produces a native sprout. I have several more young native plants to pot up, and at least 50 clumps of grasses (mostly blue grama, side oats grama, but also a few rattlesnake and prairie brome) in need of the same. Before planting these in their final places in mid to late August, I will till in a portion of the ten cubic yards of compost mix we had delivered last month. This may give the native plants a fighting chance among the highly competitive weeds.

Some of the remaining compost will make it into raised planters I have been building. Below is one of two I have placed around my already growing potatoes -the only vegetables I got in on time this year. As they grow, I have been adding compost mix. When all is done, there will be eight raised beds, a prospect I am quite happy about. Two years of growing vegetables in beds surrounded by the lawn and excessive summer rains have led to lawn that is nearly seventy five percent creeping charlie. The other twenty five is clover that co-existed nicely with the grass. Raised beds will be easier to work, weed, plant and harvest, but most of all I appreciate the architectural structure they add to the vegetable garden on a small front lawn (of creeping charlie). For all my interest in wild-ish native planting, I still like the perception of order in the vegetable patch.

Garden Architecture


After 15 years, this greenhouse of redwood and polycarbonate, has finally come out from under tarp and mouse droppings. It was purchased for my project at Socrates Sculpture Park in Long Island City, Queens, in 2001, assembled amidst the acrid haze of September 11, and the structure became a refuge during a very dark time. The company, Gardenhouse, generously donated their profit by giving the structure to my project at their cost.

Our site, formerly Rex's dog pen, was excavated last fall and filled with Class 5 gravel (a mixture of 1 inch or less rock, sand and some clay), hand compacted by me this spring, and laid with the cheapest concrete pavers from a preferred regional box store. Redwood is great for this kind of structure because it really doesn't warp and is one of the best rot-resistant woods. The polycarbonate held up well, but I hosed down the panels last fall and the hard water left spots inside the double walls. Oh well, still have a greenhouse! 


Because thunderstorm winds are a concern, Betsy made L-shaped pins from two-foot long, 1/2 inch rebar which holds down anchoring straps at seven points along the perimeter. As they rust, the pins will bind to the soil which provides extra grip. Also around the perimeter, I laid landscape fabric and 2 inch granite gravel dug from nearby "landscaping" in anticipation of high speed rain runoff from the 45-degree pitched roof, weeds, and the little boost of rock's heat retention. The brick edging is an unfortunate compromise.

I am renovating a portion of our front porch deck so that I could use the old, long cedar planks as framing for our raised herb bed. After ensuring the rusty screws and nails were out, I ripped the boards on the table saw to cut out the rotted sides. The heart of these boards are perfect, so if you are looking for free raised bed material I would look for a deck carpenter in your area. Our boards haven't been treated in at least sixteen years, if ever, and each had a nice coating of algae and lichen. Still, I placed the up-side out and the underside toward the planting. You could do the same if you are concerned or unsure about the treated nature of free, old deck boards.



After building the first raised bed I rather liked the structure over the hastily made front yard vegetable beds of last year. I had potatoes to plant and thought a raised bed would be easiest for "soiling up" mid season. I tilled, built the two side walls out of 14 foot old cedar deck boards, added humus from the base of a giant old oak tree that spits out a fine, peaty substance from a portal 5 feet up its trunk, then added the rotting straw that covered the garlic beds, and finally several cubic feet of compost. I left the 40-inch end boards off so I could run the tiller through to mix these ingredients in. 


I dug a trench and planted the potatoes at about 12 inch spacing, covered the potatoes, then dug the center trench and so on. In a raised bed with rich soil I am anticipating that I can tighten my spacing. Don't take my word for it, however, see Rodale's 7 Ways to Grow Potatoes.



The greenhouse, nearly completed (still rocks for the back and side, one vent operator to install and some window cleaning). We moved our New Mexican Opuntia and Agave inside the greenhouse, mostly to avoid the cold rains, but also to get them more sun than the house could provide. The front of the greenhouse will be tilled and seeded for grass, then stepping stones or maybe brick walkway from the garage pad to the door. 



Inside the greenhouse, on a quick-built table made of cedar taken off the house last fall, are starter trays and cold-stratified milkweed seeds of seven varieties. I am generally two weeks behind on most projects, so these got started a little late, but milkweed enjoys warm soil sprouting (you'll notice even well-established plants are some of the latest to come up). The milkweed seedlings are sprouting and now share the table with summer vegetable seedlings and strong-looking starts purchased last week at one of our area's better unique and heirloom variety vegetable nurseries -Shady Acres.

If you are thinking of a free-standing greenhouse like this, I'd like to offer some considerations. Make sure you have a solid base to build on that is level as these greenhouses won't piece together well if they are bent out of form by off-level pads. Make sure you place it in a sunny location! Don't laugh, if you build in fall or early spring it could be quite sunny, but not from May through October. Do consider wind and overhanging branches. Gardenhouse says it can withstand a wind load of 85 mph. Why chance it? Make sure to anchor it in some fashion, put it in an area that provides a windbreak yet doesn't allow a large limb to come down on it (note that home insurance usually doesn't cover structures like these). Finally, if you have lots of paper wasps, they will love to explore your new greenhouse as a fine place for their nests of stinging motherf$#ers. I was stung four times last year, mostly because I put my hands near a nest I could not see. Paper wasps are very observant and will watch you as you get close. They will leave you be if you do not get too close, but if you do, in a flash one or more will drop on you and leave its painful stinger. In short, you may have to spray a long term pesticide on the rafters, as difficult as that decision is. Wear a mask, cover your skin and eyes, because it's hard to avoid getting doused when spraying up into a pitched roof. Don't forget places like under a table. The long term stuff should last all season, meanwhile you can use clear sealant to close up gaps that allow creatures in, and with some luck, the next year you will not have to spray.
