In A Greenhouse, Do Calla Lilies Blossom Again?

Calla lilies, also known as arum or pig lilies, are herbaceous rhizomes from southern Africa and belong to the Zantedeschia genus in the Araceae family. They require moderate to high relative humidity (RH) for good development and growth, with a suggested level of RH ranging from 65 to 75 percent. Proper watering practices are essential for healthy Calla lilies, which can be grown in pots.

Potted Calla Lilies can last for approximately four months in an active state of growth, including foliage growth in the first six weeks and six to eight weeks of blooming. They are summer-blooming bulbs, so they should be planted in the spring after all danger of frost has passed. Ideally, soil temperature should be 65 degrees or warmer.

Calla lilies are perennials and can continue to produce new growth and blooms year after year under the right growing conditions. To thrive, they should be planted in a warm greenhouse after a chilling period, and deadhead the flowers when they bloom. Frost-free conditions are essential as calla lily hybrids are tender.

Plant calla lilies in the spring after all danger of frost has passed or when the soil has warmed up to at least 65°F, in full sun or partial shade. Plants bloom even longer outdoors than indoors, and only remove faded flowers when they turn brown. The most important factors to consider when growing potted calla lilies are soil medium, irrigation, and greenhouse climate.

How long do indoor potted calla lilies last?

Potted Calla Lilies last for 3 weeks to several months. After blooming, they should go into dormancy by not watering, allowing the foliage to die back, and placing the plant in a dark area below 50F but above freezing. After 2-3 months, bring the plant back into light and begin watering and feeding it. Calla lilies prefer bright but indirect sunlight with average home temperatures, so avoid full sun and keep it away from central heat or A/C vents.

Easter lilies, a popular spring plant, are known for their trumpet-shaped, pure white blooms and sweet scent. They are often discarded when their flowers fade, but with proper care, they can be kept and added to flower beds for years to come. They grow best in USDA Hardiness Zones 4-8, requiring well-draining, rich soil with regular moisture. Due to their large flowers and height of about 3 feet, they can flop over, so place them where they can lean against other plants while still getting plenty of sunshine. Bamboo stakes and grow-through plant supports are also options. However, the FDA warns that all parts of an Easter lily are toxic to cats, causing kidney failure and necessitating vet care.
