How to Grow Colored Calla Lilies? Growing Methods and Precautions

SummarySoil: For colored calla lilies, choose a breathable, well-draining, sandy, acidic soil for growing, and a layer of coarse sand grains can be spread at the base of the potting soil. Temperature: They prefer a semi-shaded environment, with a suitable growing temperature of 22-30°C; in autumn and winter, insulation measures need to be taken. Light and water: During the vigorous growth period, sufficient light is needed, as well as sufficient water; during the slow growth period, they are relatively shade-tolerant. Fertilizing: Mainly apply phosphorus fertilizer and potassium fertilizer; if seeds are to be kept, after fruiting, spray potassium dihydrogen phosphate solution every 10 days.

I. Methods for Growing Colored Calla Lilies

1. Choosing Soil

When growing colored calla lilies, choose a sandy, acidic soil with good breathability and good drainage, and place a layer of coarse sand grains at the base of the potting soil. During this time, 1/3 garden soil and leaf mold can also be added, which helps promote robust growth of the colored calla lily.

2. Suitable Temperature

Colored calla lilies like to grow in a semi-shaded environment. When growing them, avoid direct sunlight. The suitable growing temperature is 22-30°C. When the temperature is below 20°C, the growth rate of the colored calla lily becomes slow, and in severe cases it stops growing. In autumn and winter, insulation measures need to be taken for colored calla lilies, and they can be grown in a warm and humid environment.

3. Sufficient Light

Colored calla lilies like to grow in a humid and warm environment, but at different growth stages, the light conditions required by colored calla lilies also differ. When colored calla lilies enter the slow growth period, they are very shade-tolerant, so their demand for light is not very high. However, when they enter the vigorous growth period, very sufficient light conditions are needed.

4. Proper Watering

When growing colored calla lilies, water according to the dryness and moisture of the soil in the pot. When the soil in the pot is relatively dry, water with an appropriate amount of water. At the same time, water can also be sprayed on the surface of the flowers and leaves to keep a certain humidity. When colored calla lilies enter the vigorous growth period, sufficient water must be supplied.

5. Reasonable Fertilizing

When growing colored calla lilies, mainly apply phosphorus fertilizer and potassium fertilizer. Fertilizing can make the soil more fertile and is conducive to robust plant growth. If colored calla lilies are to be kept for seed, after they fruit, spray potassium dihydrogen phosphate solution about every 10 days, with a suitable concentration of 0.1%-0.2%.

II. Precautions for Growing Colored Calla Lilies

The growth period of colored calla lilies is generally around August-September each year, but in June-July the plants enter dormancy, and in February-April colored calla lilies begin to bloom. During this time, sufficient light should be given, which is conducive to the plant producing robust and beautiful flowers. During the growing process, note that because colored calla lily flowers are toxic, accidental consumption can cause poisoning symptoms such as drowsiness.
