The tropical flowering kalanchoe grows well as an indoor potted plant. Both the small pink, red, yellow or white flowers and the waxy, deep green foliage provide color in the home. These succulent plants provide most of their blooms in spring and early summer, but the foliage remains green year-round. Kalanchoes require only minimal maintenance to thrive and with some care they will flower again the following year. The plant requires a period of short days in order to form new flower buds.
Set the pot near a brightly lit window. Kalanchoes require at least six hours of sunlight each day to grow well. Choose a cooler room, as kalanchoes flower best at temperatures between 50 and 70 degrees Fahrenheit.
Water the plant when the top half inch of soil feels dry to the touch. Irrigate at the base of the plant until the excess drains into the drip tray beneath. Empty the collected water from the drip tray 15 to 30 minutes after watering.
Fertilize the kalanchoe once monthly when it is actively growing in spring and summer. Apply a soluble houseplant fertilizer at the rate recommended on the package.
Prune out the old flower stems with shears once the plant stops blooming. Cut these stems off at their base. Trim any overly tall or spindly growth, reshaping the plant minimally as necessary.
Place the kalanchoe in an area that is kept dark from sunset to sunup beginning in October. A six-week period of 14- to 16-hours of dark each day forces the kalanchoe to bloom again in January. Start the long night period at the beginning of September if you prefer December flowering.
Display your kalanchoe outdoors in the summer after all frost danger is past, if you prefer.
Temperatures over 80 degrees Fahrenheit during the dark period for the plant can inhibit blooming.
