I'm in zone 6, which is Kentucky. The conventional wisdom in this area is "don't plant before Derby Day" which is always the first Saturday in May. We're about two and a half weeks away, and I had some questions about hardening off.
Here are some pictures of my seedlings that I took this morning. They seem a little small to me, but we're about to get a rare bout of good weather--low 70's for the foreseeable future.
My seedlings are about this big. This is an average sized one. I planted them on March 12. I know they're still too small to transplant, but could I begin to harden them off?
If I hardened them off now, would I have to transplant them immediately, or could they sit outside and grow while the weather is warm?
