Question: What kind of winter care do I need to give my lily-of-the-Nile?
Answer: That depends on where you live. If you’re north of College Station and San Antonio, you’ll need to have it indoors or in a greenhouse. They are sold alongside perennials in many Texas nurseries, but gardeners often buy them without being told that they’re subtropical plants. Mulch them 2 to 3 inches deep in compost or bark mulch if you intend to leave them outdoors.
