Lilium is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world.
During active growth, water freely—especially if rainfall is less than 1 inch per week. Keep lilies mulched so that their roots are cool. The mulch should feel moist, but not wet. Apply a high-potassium liquid fertilizer every 2 weeks from planting until 6 weeks after flowering. Apply a thin layer of compost each spring, followed by a 2-inch layer of mulch. Stake tall lilies. Lilies do not bloom more than once per season, but you can remove the faded flowers so that the plants don’t waste energy making seeds.After the lily blooms, you can also remove just the stem itself. However, do NOT remove leaves until they have died down and turned brown in fall. It’s very important not to cut back the leaves until the end of their season because hey help providenourishment to the bulb for next season’s blooms.Cut down the dead stalks in the late fall or early spring.Before winter, add 4 to 6 inches of mulch, simply to delay the ground freeze and allow the roots to keep growing. Leave the mulch until spring once the last hard frost has passed. See your local frost dates. See your local frost dates.
