Paul,
I am told we are coming out of this crappy weather on Wednesday. As John Z pointed out earlier, we need a lot of elevated degree days and fast.
As for plants, I've got a cold frame full of vegetable seedlings clinging to the plastic door and sides begging for light and warmth. And, I've got a bunch of fruit trees with various leaf problems that I cannot help because it's too cold to spray neem oil.
The vineyards are at least semi-dromant--way late, but not in danger.
Anyway, all of this is Canada's fault. I must believe that or I would have no excuse for remaining in this part of the states...
