trumpet lily

Trumpet lilies should be watered about once per week, or whenever the soil feels dry up to an inch deep. Water deeply, saturating the soil evenly to encourage deeper root growth. Do not let the soil become soggy or wet. Overwatering can cause root-rot, so it is important to only water when needed. Fertilize trumpet lilies after flowering with a balanced, slow-release fertilizer.

Trumpet lilies need 6-8 hours of direct sunlight each day for optimal growth. Morning and late afternoon sunlight are preferred, as the intense midday sun rays can scorch the lilies. This species should be planted in a spot that receives full sun for most of the day and preferably not in an area with reflected heat from a wall or other structure. The lillies should be shielded from strong wind and placed away from other large plants that may shade them.

Trumpet lilies should be pruned at least once a year. Pruning should be done late in the fall or in early spring, before new growth begins. During pruning, dead or damaged leaves, stems, and blooms should be removed. The center of the plant should also be opened up so that the stems can receive adequate air circulation. Depending on the size and condition of the lily, the plant may require further pruning. If possible, cut off old leaves and stems to promote new and healthy growth. If the leaves are too tall, they should be shortened so that the center of the plant is not blocked up.
