My father who cared for figs in NY when I was young used to say "wrap the trees at Thanksgiving and unwrap them at Easter". If you go by that old rule of thumb, you should uncover your tree April 14th this year. This of course applies only to our region. I would think, watching the weather closely is best and maybe wait until temps stay 40 or better at night and frost risk is low.

I meant April 12th this year. Oops.
