Frost-Free, Not Worry-Free When you live in a climate where the temperature doesn’t drop below 32 degrees Fahrenheit in winter, you can keep potted chrysanthemums where they are and they should resume growing in the spring. However, in warm-winter climates, the plants can suffer from being too wet during winter.What flowers need to be covered for frost?Frost protection is especially important for tender plants such as geraniums, begonias, impatiens, peppers, and tomatoes. In the spring, use row covers if you have tender vegetable seedlings and transplants in the spring. Row covers or garden fleece can also be used to help create a warmer environment beneath them.
