Are mums perennial and how do you overwinter them successfully?

Question

Yes, most mums (Chrysanthemums) are indeed perennial, though their hardiness varies by cultivar. To successfully overwinter them, particularly in colder climates, ensure they are well-established in the ground by late summer. After a few hard frosts, cut the stems back to about 4-6 inches. Apply a thick layer of mulch, such as straw or shredded leaves, around the plant's base to insulate the roots from extreme temperature fluctuations. For potted mums, move them to a cool, dark, frost-free location like a garage or unheated shed, and water sparingly throughout winter to prevent the soil from completely drying out.
