While they do not require special soil, lilies must not be planted in any location where water will stand on the bulbs. A porous, rapid-draining soil is best. If your soil contains too much clay, add sand, moistened peat moss, or compost to increase porosity. It has been said that lilies, like clematis, prefer their heads in the sun and their feet in the shade. The best location is one in sun or light shade among ground covers such as vinca or ferns.
Lilies grow from scaly bulbs.
The bulbs are planted in autumn, either September, October, or November, depending on your growing region. Ideally, the bulbs are sold with roots attached. Since they are never completely dormant, they should be planted as soon as you bring them home. Lilies are very attractive planted in groups. Loosen the soil to a depth of at least 10 inches, then moisten the ground where the bulbs are to be planted to promote immediate root growth.
