Unbuttoned

November 11 -a bright, sunny, and cold day. One month ago, on October 11, we had our first snowfall. Yesterday's snowfall ushered in the coldest air of the autumn. We bottom out tonight in the low single digits, but we are at 12° F this morning. There is a brisk wind, so we feel chillier than the temperature might indicate. On November 11, 1940, Minneapolis received 16 inches of snow in a surprise storm -forecasting wasn't as precise back then. In 2005, the temperature soared to 64° F on this day while 1986 had Minneapolis bottoming out at -1° F.

The many lakes of our area are open water -not yet a skin of ice on them, despite two weeks now of well-below freezing temperatures. The other day a man near Cambridge, Minnesota, not quite an hour north of downtown Minneapolis, thought it cold enough to try his feet on ice that had formed on Skogman Lake. Based on my observations, here, the ice couldn't have been more than an inch or so thick. If you've been to the lake in Prospect Park, Brooklyn, you'll notice the ice ladders stationed around it in winter. I recall watching a father and child shuffle out on the ice one day. Tragedy was averted thanks to someone more vocal than myself, whose hesitancy requires some introspection on some other day. Minnesota doesn't know what ice ladders are and I will never know confidence on ice.

As October rolls out into November, I need to have a flexibility never required by my ocean-tempered, Atlantic coast activity. We don't always have what we need, do we? Curiously, the post I just linked to, above, finished with this sentiment:

"I've grown accustomed to winter, finding solace in the recess of growth and decay. As much as I think of a new season's garden, of tomatoes and greens, peppers and garlic, it's always too much. I aim to accept what can be done and what can be done, well."

Now that winter has come to occupy an additional three months of the year, my experience of its slippery possession is that of prey who's frantic contortions allow a brief but futile escape from the quickening claws of no longer. A winter, fast, I accept like death, but with a consciousness of afterlife that offers a view to the world I no longer inhabit, a world perceivable through the bright scrim of slow-moving molecules.

planting bulbs frozen ground
Box store bulbs, fifty percent off, needed unfrozen earth to plant in. With this trouble, those bulbs should have been 75% off, no? Despite two weeks of frozen temperatures, I laid rumpled plastic, held down by bricks, over a patches of bare soil. When I planted on Saturday evening (yes, this dark at 5:00 pm), the soil was pliable under my coverings. Tulips and miniature iris -good luck!



Outdoor plants brought in for winter. Potted, pruned, and placed. Now, only fungus gnats, aphids, and watering to think about.

The vegetable beds, tangled, leafy, and snowed upon.



Remaining siding from this summer's window and siding replacement projects. I will do some of this indoors and wait for that forty degree day to come.



The rocks. In this location, under the replaced siding and adjacent to window wells, the builder had placed Hydrangea arborescens, you know -the spreading kind with giant flopping heads. Three Minnesota hardy azaleas were placed around the bay-type window to the left. Around the base of these, one and one-half inch St. Cloud granite (gray/pink/black coloration). In order to fix the siding and the kick-plate below it, the roots, the rocks, the clay, and eventually the plastic that laid deep beneath it all was removed. The hydrangea were removed a few years ago to make the driveway border. 

Many rainy days embedded the granite rocks into the black clay earth. After grading the soil to a proper slope, replacing the edging, laying new barrier fabric and sheet plastic to shed water, the granite is only partially replaced. It is frozen to the soil, now, but it also requires pressure washing to remove the clay, which will not happen until spring.




Despite the snow and the freezing, I am still working on a few outdoor things, like gravel around the apron of the studio and cobble edging to contain it, possibly some tree felling, and rebuilding the lattice that sits beneath the front porch. Given the early depth of cold, twenty to thirty degrees below average, isn't it yet possible that we will see ten to twenty degrees above average?

Gardening at the Boundary


That day, maybe a week ago, it really came down.


I know nothing about late spring snow. Nothing. When I was a child, in New York, it snowed during our Easter break -it was early April. The day prior was warm, even the day it snowed it was warm, so much so that I was out riding my bike in the street with my brother. Although it was cloudy, the big, wet flake snow came without warning.


This snowfall is different, intermittent pellets and flakes. It was windy too, driving the pellets hard. As is often the case, the snow did not stick. The snow was not the trouble at all. It was the cold that presented itself the following night. 


I woke to find a frost on the little wetland.


 Crystals coated all the leafed out, saturated-looking plants in the early sun.



The parsley I had just planted showed crystallization along its veins (interesting that this happens, no?).


The  cilantro.


The Virginia Wetleaf succumbed (but recovered) to the eight or so hours well below freezing.

____________________

The last frost date for our location is roughly May twenty. I do not think anyone would suggest that the last two months have had ordinary temperatures, we haven't. Since March, we have had days that topped out at 10ºF and 82ºF, although most have been in the forties through the sixties. Our March monthly average high temperature was nearly 46ºF and the April average so far is 59ºF. Daytime temperatures have long suggested I should be growing things that California is having trouble providing. Think twice. I watch the trees and the vegetable gardens. Only this week are the oaks beginning to show the chartreuse of spring and there has been zero garden activity.

Warm air masses, heated by their descent from the Rockies and Great Plains, move in from the south and west, and locally there is sunlight warming the thermal mass of land without the cooling influence of great bodies of water. The day warms nicely. At night, however, without the moderating influence of clouds, radiational cooling is strong. I recall a typical temperature differential in NYC to be about 15 degrees. Here, in Minnesota, I have seen 20+ as the norm. Beyond nightly cooling, there is always the threat of a cold airmass coming down from the north whenever the jet stream decides to do something funky. Minnesota is the common entry point for cold air, it is the reason people think this state is cold. 


Which brings me to another weather detail. I noticed the window box of just planted pansies was bone dry. What? I had watered it in, deeply, just the day before. Hmm. Something unusual had happened -dry air, exceptionally dry air. Two days after the snowfall, and the day of the overnight freeze, our relative humidity had dropped to 12%, twelve percent! Our dewpoint was nearly 1ºF by the late afternoon. Meanwhile, our high temperature was 55ºF and the winds were up. The water simply evaporated. Despite this, the pansies toughed out the freeze and drought, as those in the pot above attest.



The dry air, the sudden cold from the north, the high temperatures, the wind, no rain, and of course, heavy rain are all typical. We live at a climactic boundary with little to moderate each influence. This is the education of a gardener.
