How to Grow a Regal Hybrid Calla Lily

By Home & Garden Last updated Saturday, June/15/2024

1). Fill a 4-inch flowerpot three-quarters of the way with potting mix. Mix in compost until it is an inch or two from the top.
2). Dig a hole in the soil about halfway down and place the bulb on its side. Cover with soil.
3). Water the pot once or twice a week, allowing the soil to dry out a little each time. Be sure that the pot has adequate drainage so that the roots don’t have problems with mold.
4). Place the pot in a window with plenty of sunlight.
5). Water the plant with an all-purpose fertilizer supplement once or twice a month to ensure the plant does not suffer from depleted nutrients. If the soil provides enough nutrition, the plant may flower all year long. Signs of malnutrition include burned leaves (brown or shriveled) or no flowering for long periods.
