Allow the plant to drain before replacing it in its decorative pot cover. After the last bloom withers and is cut away, plant it out in your garden to enjoy it for years to come. Place it in a sunny location with an eastern exposure. It prefers a well-drained garden bed rich in humus. Your nursery has several kinds available.
Good drainage is the key for success with lilies.
To ensure adequate drainage, raise the garden bed by adding good soil to the top of the bed, thus obtaining a deeper topsoil and a rise to the planting area. Plant the bulb 3 inches below ground level, and mound up an additional 3 inches of topsoil over the bulb. Spread the roots and work the prepared soil in around the bulb and the roots, avoiding any air pockets. Water immediately and continue to water thoroughly as needed. Add a houseplant fertilizer every 6 weeks using the dosage recommended on the label.
