  • For best results, sidedress monthly with bulb fertilizer.

Calla lilies make great housplants if a sunny window is available, although they may need a little protection from the sun at midday. Plant the tubers in early fall, setting them 3 inches deep in the potting mixture. Keep barely damp until the first shoot appears, then keep moist and feed monthly with a bulb fertilizer. Most callas need a period of dormancy after flowering. Gradually withhold water until the leaves wither away, then start plants into growth again later by moistening the soil.
