Taking care of phlox during the winter involves mulching and avoiding excessive moisture. After the first hard freeze, apply a thick layer of mulch (about 2-4 inches) around the base of the plants to protect the roots from fluctuating temperatures. Ensure the soil drains well to prevent waterlogging, as phlox is susceptible to root rot in overly wet conditions. Additionally, cut back the foliage to help prevent disease. In spring, remove the extra mulch to allow new growth to emerge.
