Kalanchoe Plant Care


Kalanchoe is a genus of about 125 species of succulent plants, herbs and climbers native to tropical regions of Africa, Madagascar and Asia. Kolanchoes are grown for their interesting foliage and bright clusters of flowers. Because they are tropical plants, kolanchoes are often cultivated as indoor house plants.


Kalanchoes range in height from 15 inches to 3 feet in height, with 6- to 15-inch spread, depending on the species. Their leaves vary from small to large and glossy to fuzzy and range in color from grayish to dark green. Original kalanchoes produced bright red blooms, but through cultivation, now come in shades of yellow, white, pink or purple. Its ¼-inch flowers grow in terminal clusters called cymes and bloom during various seasons depending on the species.


Kalanchoes are used outdoors as an annual bedding plants in all but the warmest climates. They are also grown in greenhouses and are common house plants. Kolanchoes are used for containers and landscape edging and attract hummingbirds.


Outdoors, grow kalanchoes in full sun to partial shade after danger of frost has passed. Grow kalanchoes on a variety of well-drained, rich soils and keep reasonably dry during the winter when grown in warm climates. Propagate kalanchoes by seed or cuttings. Kalachoes are cold hardy in USDA zones 9 though 12, depending on species. Indoors, Kalanchoes prefer a moderately rich, gritty, well-drained potting medium. Greenhouse and indoor cultivated kalanchoes require good sunlight to prevent stem stretching. Fertilize plants with diluted houseplant fertilizer every few months. Ideal temperatures for kalanchoes are 45- to 65-degree nights and 50- to 70-degree Fahrenheit days. Prune and repot, if desired, after flowering has finished for good future blooming.

Selected Species

Kalanchoe blossfeldiana is commonly grown as an indoor houseplant. It has deep red flowers and reaches 15 inches in height. Kalanchoe daigremontiana, with gray-violet flowers, is a winter bloomer and grows to 3 feet in height. Kalanchoe thyrisiflora is a spring bloomer with yellow flowers and grows to 2 feet tall.


Pests of outdoor kalanchoes include caterpillars and mealy bugs. Leaf-spotting problems can occur with humid conditions and root rot can be a problem for plants grown in inadequately drained soils. Other pests of Kalanchoe are aphids and brown scale. Eliminate these, along with mealy bugs, by wiping them off with rubbing alcohol using a cotton swab, according to Clemson University Extension.
