How to protect seedlings in a greenhouse during night frosts; even on May 9, 2024, nothing froze!
May 9, 2024, was the coldest day ever recorded. Snow fell on the evening of May 8 and remained until the afternoon of May 9. But what about the seedlings in the greenhouse? It turns out I prepared for this kind of frost last year by sewing two pieces of covering material together, and now I can easily cover my greenhouse during night frosts, but of course, I won't be able to do without heaters.
