I've got my sweet peas (and some other autumn-sown things) growing on a a little make-shift cold frame made up of a wooden box, lined with bubble wrap, and covered with some horticultural fleece, to keep the air circulation. They've been doing fairly well, but we had a week or so of pretty hard frost where it never went above freezing even during the day, and now we're into a freeze-thaw-freeze-thaw pattern. Some of the sweet peas look fine, but some have gone all floppy, and the stems appear almost crushed.
I imagine they got thirsty when their soil was frozen. Now, the soil is fairly dry, so my question is, should I water, or will that do more harm than good, given that we'll be having more hard frosts?
Thanks a lot!
