Kalanchoe Care: Key Points for Light, Watering and Flowering Season Management

Kalanchoe (Kalanchoe blossfeldiana) is a perennial succulent herb in the genus Kalanchoe of the Crassulaceae family. Also known as the longevity flower and dwarf kalanchoe, it has a compact, low-growing form with thick, deep green leaves. Its natural flowering season is mostly concentrated in winter and spring, and the flowers come in many colors such as red, pink, orange, yellow and white. The blooms grow in dense clusters and last a long time, and since the plant carries an auspicious meaning, it is one of the most popular potted flowers for the Lunar New Year.

To grow kalanchoe, use a loose, airy, sandy soil, which can be made by mixing leaf mold with river sand or perlite; placing a drainage layer at the bottom of the pot is even safer. It likes a sunny environment, and apart from light shading at midday in summer, it should get plenty of sun in other seasons. Insufficient light easily leads to leggy growth and sparse flowering. Follow the principle of watering thoroughly only after the soil has dried out, and never let the potting soil stay wet for long periods, otherwise the thick roots and stems rot easily.

The suitable growing temperature for kalanchoe is around 15 to 25 degrees, and in winter it needs to be moved indoors for warmth to avoid cold damage. It is a short-day plant, and once daylight shortens in autumn it is more likely to differentiate flower buds. If you want it to bloom on schedule, you can regulate the flowering period by blocking light. Supplementing with phosphorus and potassium fertilizer during the bud stage makes the flowers brighter and longer lasting.

Kalanchoe is mainly propagated by cuttings. Cut healthy stems or leaves, let the wounds dry, then insert them into a slightly moist medium, and they will quickly root and survive. In everyday care, if the stems and leaves become leggy, it is usually due to insufficient light; simply increase sun exposure and pinch back appropriately to improve it. After flowering, cut off the spent flowers and replenish nutrients, and the plant will soon regain its vigor.
