Greetings,

We've got a cold front moving in and will be getting temps in the 40s the next few nights. Do I need to cover my veggie plants or is that only necessary with freezing weather?

Thanks,

Michael

Tomatoes prefer nights above 55°, but nights in the 40s won't hurt them -- they just won't ripen fruit, or will ripen very slowly. So if you cover them, radiated heat from the earth will be held around the plants and they'll ripen sooner.

I've read that tomatoes won't set fruit at temps below 47. I'm sure some expert got paid a fortune to figure that one out :D However, I am babying one through winter in the greenhouse to see if I can get early fruit. Our coldest night so far has been 28 Frost outside, but I think not in the greenhouse.
If you are expecting another warmup, I'd say cover it with remay/leaves/straw or tent them with hot water bottles. Good luck!
