Flowering Kalanchoes are available in red, pink, yellow, or white. Like many succulents, these are not difficult plants to grow, providing you are careful with the water, especially in the winter.
Growing Conditions
Light: They prefer bright, sunny locations, especially in the summer growing season. During the winter, consider a south-facing window.
Water: Water moderately throughout the summer and reduce watering in the winter. Let the soil surface dry out between waterings, and in the winter, the plant can almost dry out. Watch the fleshy leaves for signs of water distress.
Temperature: They prefer warmth. Do not let fall below 55ºF (12.7ºC).
Soil: Well-drained, light soil, one suitable for succulents.
Fertilizer: Feed bi-weekly in the summer with a liquid fertilizer, or use slow-release pellets.

Grower's Tips
Kalanchoe care is minimal but be cautious about light levels. Strong southern light can burn the tips of the leaves. Place pots in partial sun to light shade areas when growing Kalachoe plants.
The flowering varieties (K. blossfeldiana) are highly rewarding for their colorful and long-lasting flowers. Many people discard the plants after the bloom is over, but this isn't really necessary. Simply cut off the flowering head, let the plant rest with reduced water, and resume its normal care. It should flower naturally in spring. Professional growers force Kalanchoes to bloom throughout the year (they are a short-day plant). The two pendant Kalanchoes make excellent hanging plants.
Repotting
These small plants native to Madagascar require repotting every few years. When re-potting, take additional care in handling as the leaves are somewhat brittle and can snap easily. Clay pots work exceptionally well for planting Kalanchoes. Ensure pots can drain well, and saucers can empty easily.
After planting, water thoroughly to settle the soil and fill air pockets. Thereafter keep the plant on the dry side for active growth and continuous bloom.
Propagation
Many kinds of Kalanchoe will produce tiny plantlets along the leaf margins that can be individually potted up. These types include The Air Plant (K. pinnata) and K. beharensis. The more popular K. blossfeldiana and K. manginii can be propagated by leaf cutting or tip.
Pests and Insects
Kalanchoe is resistant to most insects and diseases. But if raised outside, bugs such as aphids, mealybugs, and spider mites may infest it.Also, you can control these insects by applying organic insecticides.
You can also make your own all-natural insecticide by mixing a few drops of sunflower oil, a few drops of dish soap and a liter of water.
Apply the insecticide directly to the infected area.
