Even tho it got no where near freezing in most places in my neck of
the woods, for some reason my nursery is situated in a frost pocket &
I noticed all the paw paw & grape starts had their growing tips nipped
by frost. I'm guessing that's gonna set them back 2-3 weeks. Is
there anything I can do to minimize the setback. Maybe hit them with
a foliar spray of fish emulsion?
