Why do kalanchoe leaves turn yellow?
Zinc insufficiency is a problem for Kalanchoe blossfeldiana, which is exacerbated by excessive phosphorus levels in the soil. Yellowing of leaves between veins, as well as curling, withering, and leaf deformation, are all signs of zinc deficiency. Zinc deficiency in Kalanchoe can result in fasciation, which is a highly branching, flattened stem. Kalanchoe requires a soil pH of 6.0 to 6.5 or a rich growing medium of equal parts peat and perlite to reduce the risk of zinc deficiency.
How many hours of sunlight does a kalanchoe plant need?

Kalanchoes are low-maintenance succulents with clusters of tiny blooms borne on spreading bracts. They are usually cultivated indoors, but they can be moved outside if the weather is warm enough or if the winter temperatures are not too cold to kill them. Kalanchoes, whether grown indoors or outdoors, require bright sunshine, dry times between waterings, and space to develop their root system.
Hardiness Zone
While temperatures between 50 and 60 degrees Fahrenheit (10 and 15.5 degrees Celsius) can maintain the Kalanchoes in bloom, freezing temperatures will kill them. They can be planted directly in the landscape with minimal winter protection in USDA hardiness zones 10 and 11 and will function as perennials. Unprotected Kalanchoe can be killed by even a few hours of temperatures near 40 °F (4.5 °C).
Location
Kalanchoes are attractive in and out of bloom, but they require a lot of light to bloom. Kalanchoes grown in areas where nocturnal lighting reaches the leaves may not flower as frequently as those grown in areas where there are significant periods of darkness at night. Summertime sunshine in USDA hardiness zones 10 and 11 can scorch the leaves. Kalanchoes benefit from more winter sun and less summer sun when planted near a deciduous tree with dappled shadow.
