When to set out herb seedlings (mint, thyme)
I have some starts of corisican mint and creeping thyme that I started from seed. Now I see the Corsican mint is perennial for zone 7, I was wondering, because we are certain to have frosts here for about a month or more, if I can set them out yet? I was thinking that the "zone 5 winter conditions" are surely over, and if they can handle zone 7 type stuff (mid 20's?) then maybe they would be OK after I harden them off? What about the creeping thyme? I desperately need more room under my grow lights, and was hoping to start hardening off these herbs if they are tough enough, and get their little fragrant selves outside.
