They carry the most flowers of all, but may not have the same initial impact. Because of their grace and beauty, the pendant lilies are a valuable addition to the perennial border, especially when massed in groups. Within these major groupings, lilies are also classified as to their season of bloom. Lilies are best planted in late October. Although the bulbs are never truly dormant, they do go through a resting period at that time, when top growth has died down, and bulbs can be lifted, sorted, shipped and replanted.
Good drainage is probably the most important single factor in successful lily growing.
They will not tolerate locations where water collects after a rain or where melt water remains in the spring. Gardeners can improve drainage, as well as a heavy soil structure, by building raised beds with the addition of coarse sand and peat moss. Digging the soil to a depth of 30-50 cm. Lilies do best in a sunny location, although most will perform well given only afternoon sun. Planting depth will depend on both the size of the bulb and the soil type.
