I hope that when I reported
that the
Persephone Days were over, you didn't rush out to
plant your spring vegetables. Once daylength is longer than ten
hours, surviving crops like kale will start growing again, but that
doesn't mean the
ground is warm enough for seeds to sprout.
Lettuce, onions, and
spinach can all handle soil temperatures as low as 35 while most other
spring crops like the earth to have warmed to at least 40 degrees
Fahrenheit. I tested the soil
temperature in the
sunniest part of our garden last week, and the ground underneath our
quick hoops was just barely 35 degrees, while unprotected soil was
hovering right around freezing.
Most of the plants under
my quick hoops are starting to grow again, but the tatsoi totally
perished in the winter cold. That means I had a spot just waiting
to plant spring lettuce! Rip out a few weeds, toss down a bucket
of composted manure, then sprinkle on lettuce seeds, and the first
garden bed of 2012 is seeded for March harvests.
