As the thermometer plunges to 40 degrees, a pressing dilemma arises for gardeners: should I cover my tomatoes? This question isn’t as straightforward as it seems. The delicate nature of tomato plants makes them vulnerable to cold snaps, and when temperatures drop, it can create panic among devoted cultivators.
