Yup, 24.6 F this morning, first hard freeze this fall, PA Zone 5B, so the official growing season is over.

Added on edit, under the low hoop house tunnel it is 28.9 F. Spinach has frosty leaves and mesclun we planted a few weeks back is coming up.

I received Elliott Colemans Winter Harvest book and it's excellent reading for hoop house growing.

27 here in Culpeper at 5:30 this morning. Dogs were, like, "you guys don't pee outside in this kind of weather, why do we have to?" LOL!!!
