Kalanchoe plants are flowering plants and are succulents like the cacti. These tropical plants have a total of 125 species and are native to Madagascar.
Like other succulents, you are not allowed to over-water Kalanchoe plants. They require a little watering. Not only you should allow the soil to dry between waterings but also allow it to stay dry for a couple of days.
They need bright sunlight. Direct sunlight is not really a problem, however in summers the direct sunlight can cause the leaves to change their color and look burnt.
As they are succulents, you must use a quick draining media for them. The appropriate pH for the soil would be 6.0 to 6.5.
Protect them from cold. Bring them indoors in winters if possible. IF you live in hot climate areas then the plant will be fine outdoors.
Depending on the species, you can propagate Kalanchoe plants through cutting, division and also by planting the babies they produce. They have small seeds and if you can obtain these seeds, the plants can easily be propagated through seeds also.
