How to grow calla lilies? Their cultivation methods and precautions
Many people like growing plants, and calla lilies are deeply loved by everyone for their unique flower shape. Today the editor brings you the cultivation methods for calla lilies, telling you how to grow them.
Calla lilies like fertilizer. From leaf growth until before flowering, apply light fertilizer frequently, using a nitrogen, phosphorus and potassium compound liquid fertilizer or granular fertilizer about once every 10 days.
Calla lilies like light, but fear summer exposure. From mid-autumn growth until winter and spring flowering, they need plenty of sunlight. Especially after being moved indoors in winter, they should be placed in front of a windowsill during the day to get more sun, and flower spikes may begin to emerge around New Year's Day and Spring Festival. March-April is the peak flowering period, and in late May they should be moved to a ventilated, shady place.
Calla lilies like warmth and fear extreme summer heat. The most suitable temperature for their growth is 15-25°C. Move them indoors around Frost's Descent; if a temperature above 10°C can be maintained, flowers can be expected around Spring Festival, below 10°C the flowering period is delayed, below 5°C growth becomes sluggish, and at 0°C they may die. In spring, they should be taken outside when the lowest temperature is stable at 10°C. The high-temperature period in summer is their dormant period. In places without extreme summer heat, after flowering in May, repot and change the soil, then keep them in a shady place for care, and they can bloom again in August-September. After flowering, repot and change the soil again, and shift to autumn care.
Calla lilies are mainly propagated by division. When repotting and changing the soil after autumn, break off the small tubers growing around the tubers and plant them separately. After 1-2 years of cultivation, they can bloom in 3-4 years.
When ventilation is poor during the growing season, calla lilies are most prone to aphid damage. When pests occur, spray a 40% omethoate 1500-2000 times solution for control, and pay attention to improving ventilation conditions.
