Sometimes, produce like peppers, tomatoes, and watermelons need a few more weeks to fully ripen, especially if they got a late start due to a cold spring. But plant covers aren’t just for edibles. They can also help delicate decorative flowers like begonias and impatiens last a bit longer in your landscaping. They can even protect shrubs and bushes during unusually cold weather. Check for your specific plant type and hardiness zone.
