Should I Cover My Plants At 32 Degrees?
Covering plants at 32 degrees Fahrenheit makes sense when tender annuals, warm-season vegetables, or tropical plants face a brief light frost. It is usually unnecessary for hardy perennials, cool-season crops, or spring bulbs that tolerate near-freezing temperatures. The right choice depends on the plant’s cold tolerance, how long temperatures stay at or below freezing, wind, and whether you can install and remove covers properly. This guide walks through the trade-offs so you can protect your garden without causing more harm than good.
