Although kalanchoe (Kalanchoe blossfeldiana) is often purchased as a gift for Christmas or Valentine's Day, the plant will remain gorgeous all year-round with a bit of tender loving care. In the right conditions, Kalanchoe will bloom profusely, producing clusters of flowers in bright shades of pink, magenta, red, white, yellow and orange. Even when the plant isn't actively blooming, the big, succulent leaves make kalanchoe a worthy indoor plant that will thrive with little attention.
Place kalanchoe in direct, bright sunlight. Without adequate sunlight, the plant will become spindly and weak.
Keep the plant in a fairly cool room with temperatures between 60 and 70 degrees Fahrenheit. Nighttime temperatures should be approximately 10 degrees cooler. Never allow temperatures to drop below 40 degrees Fahrenheit as kalanchoe isn't cold-tolerant.
Water kalanchoe deeply and allow water to drain through the hole in the bottom of the pot. Allow the potting soil to drain thoroughly, then pour out any water that remains in the drainage saucer under the plant. Never allow the plant to stand in water. Water again when the soil feels dry.
Feed kalanchoe once monthly during the growing season, using a regular fertilizer for indoor plants. Withhold fertilizer when the plant is dormant.
Allow the plant to go dormant for 12 weeks beginning in late September or early October. Place the kalanchoe in a room where the plant will be in the dark for 14 to 16 hours a day, which simulates the natural winter environment. Move the plant back into the light when you can see flower buds above the foliage.
Remove the flowers after the blooms have faded. Use pruners or kitchen shears to cut the plant back to the desired shape and size if the plant is getting leggy.
