Kalanchoes are succulent plants with flat, glossy, green leaves. Kalanchoes will also bloom with small pretty flowers in shades of reds, pinks, oranges, and yellows. Kalanchoes are easy to care for, but getting them to re-bloom can be difficult. To re-flower, kalanchoes require short days. This can be stimulated by placing the kalanchoe in total darkness for 12-14 hours a day for 6 weeks during the early fall. Another method of developing flowers is to let the kalanchoe rest during the winter, and cutting back on water and fertilizer. This may produce some flowers in the spring.
