After the blooms begin to fade and die off, don’t throw them away. Plant them in your yard. Lilies will grow and bloom in your garden for years to come.
Wait until all chances of a frost have passed and transplant your lily in your garden. Plant it in full sun, in somewhat of a rich soil and in a well-drained area. In the fall, apply bulb fertilizer or blood meal on top of the soil and carefully work it in without disturbing the bulbs. Cover with mulch in colder climates to protect the bulb from freezing.
Don’t panic if your lily doesn’t come back until the second year after it is transplanted. Sometimes bulbs have been forced to bloom and need a year to recover and return to its normal cycle.
