I have never put veggies out this early in the year, but with up to 80 degree days and mostly 40 degree nights I decided to try it. Wish I had not. I covered the plants as a rep from Bonnie told me, read a bit on line, and decided to chance it. Yup, bad move, everything died. I mourn the loss of the money I paid for the veggies, and the veggies, but now I know that for me, at least, it doesn’t work.
Too much moisture and the water in the plants themselves can freeze, which it did, and then the plants freeze, and that is that. A half frozen plant might grow but not very well. This is the same problem that greenhouses have, moisture control. Glastd I never bought a green house.
In the second picture, I am using a pallet as a climbing fence for cucumbers. I put grow pots over the cucumbers and they survived the night just fine. I have always used pots as covers, not plastic. Plastic was clearly a mistake. I will not rebuy more veggies till May.
