As the flowers open and mature, remove the yellow anthers before the pollen starts to shed. This gives longer flower life and prevents the pollen from staining the white flowers. When a mature flower starts to fade and wither, cut it off to keep the plant looking attractive. After the last flower has withered and has been cut away, the Easter lily can be planted in the garden after the danger of frost has passed. Prepare a well-drained garden bed in a sunny location amended with organic matter such as compost.
Good drainage is the key for success with lilies .
To ensure adequate drainage, create a raised garden bed by moving soil to the top a few inches higher than the surrounding soil level. Also, adjust the soil pH to 6.5 to 7.0. Plant the Easter lily bulbs 6 inches deep from the base of the bulb to the top of the mulched surface, assuming at least a 2-inch layer of mulch. Plant them 4 to 6 inches apart. The hole should be wide enough so the roots can be easily spread out.
