WOW. We have ZERO snow here. We got an inch 2 times. It melted last week. Now we have 3 days of zero and subzero nights. Brr. But back to 30 by mid-week. Such an odd winter.
What flowerbug said. We have a large 12X12 that DH has tried so many times to get warm enough and stay warm enough over night to grow in the off season. Always end up with dead plants because we'd get a hard freeze after they sprouted. Maybe a smaller area would be doable?
