I have all my tomatoes, peppers, marigolds, basil, cucumbers and squash plants covered in plastic hot houses since last night. I'm not taking any chances with the weather. It's suppose to dip down to 38-41 tonight, that's too cold for my liking and don't want to loose any plants. The wind has been fierce today and if it's too cold for my bones then its too cold for the plants. I probably won't take any of the covers off til maybe the weekend.
