Cultivation methods and precautions of Kalanchoe

1. Temperature

The ideal temperature for Kalanchoe is between 15-25℃. It will enter a dormant state above 30℃ and below 5℃. If the temperature is above 24℃ in summer or below 10℃ in winter, its flowers will not perform well.

2. Lighting

It is a sun-loving flower. Placing it in a well-lit location in winter and spring will promote the opening of the flowers. During the midsummer dormancy period, avoid direct sunlight and place it in a place with bright scattered light.

3. Soil

The potting soil should be loose and breathable, preferably sandy soil with humus content, and water accumulation must be avoided.

4. Watering

When watering Kalanchoe, you must follow the principle of watering thoroughly when the soil is dry. Do not allow water to accumulate in the soil for a long time. During the flowering period, just keep the soil in the pot slightly moist. Long-term waterlogging will cause root rot, yellow spots will appear on the leaves, and the flowering period will be shortened.

5. Common pests and diseases

1. Aphids: They reproduce very quickly and require frequent intervention.

2. Scale insects: They mainly occur in poorly ventilated areas with relatively constant humidity. You can wipe them off with cotton or soft cloth dipped in neutral detergent. You can use carbendazim or cypermethrin for prevention and control.

3. Powdery mildew: It can be prevented with garlic juice. Before the disease occurs in these two seasons, you can spray diluted garlic juice on its leaves. After the disease occurs, you can spray oxycarboxin to control the disease.

6. Notes

In the middle and late stages of the flowering period of Kalanchoe, that is, the period from the late Spring Festival to early summer, the withered flowers should be pruned off in time, and the upper part of the flower clusters can be completely removed by heavy pruning. Leave the lower 3-5 leaves and let them sprout again. As long as there are sufficient nutrients, it may produce a second flower, which will extend the flowering period and make the plant shape more complete.
