Lettuce isn't quite
hardy enough to survive even a mild zone-6 winter despite quick-hoop protection. But the
row-cover fabric produces a protected microclimate that pre-heats the
soil for spring...while also growing quite a sturdy crop of dead
nettle, chickweed, and speedwell.
I've hand-weeded beds
like this in the past...and it's a bad idea. One of my goals for this
year is to think of smarter ways to handle body-breaking tasks, so I'm
experimenting with two early spring weed killers.
Option A: (in the
foreground) solarization, which I really don't expect
to work at such a cold time of year. Option B: a short-term cardboard
kill mulch, which I expect to weaken the plants within a couple of
weeks and make them easy to handweed.
Perhaps Mark should pull
out the flame
weeder and see if we
can come up with an experimental option C?
