Caring for Plants After Extreme Cold

Extended periods of extreme cold can wreak havoc on your plants. While a lot of plants can handle temps below freezing, prolonged exposure to excessive cold and high winds have the potential to kill them. As your partner in the garden, we are here to help you come up with a solution to salvage existing plants and to help you pick out/care for new ones.

Shriveled foliage with a dark green/gray color is a sign of cold damage and the plants will likely need to be replaced. The violas in this photo will likely not recover.

The excessive cold has likely damaged most of the cabbage and kale in the landscape as well. Cabbage and kale foliage that has turned a tan color should be pulled and disposed of.
