Flaming Katy Care

Flaming Katy kalanchoe can be grown outdoors in USDA zones 10-11, but is more commonly grown as a blooming houseplant during the winter months. With proper care including lighting, water, temperature, humidity, soil, and fertilizer, your Flaming Katy will likely live to bloom yet again, in fact, this kalanchoe blooms every 6 months or so for 6 weeks or longer!

Light

Direct sunlight can burn the leaves of this delicate kalanchoe, so situate it in an area of indirect sunlight or partial shade.

Water

While kalanchoes like moist soil, overwatering can lead to root rot, so be sure that the top 1-2 inches (2.5-5 cm) of soil feels dry to the touch before watering.

Temperature & Humidity

Keep your Flaming Katy in an area of between 60-75 F (15-24 C) during the day and a bit cooler at night, about 50-60 F (10-15 C).

Soil

Kalanchoes thrive in soil that is well-draining, such as a cactus or succulent mix. Or make your own succulent soil using equal portions of coarse sand, perlite and potting soil.

Fertilizer

During the active growing season, use a balanced water-soluble fertilizer every 4-6 weeks.

Problems, Pests & Diseases

Kalanchoe can be afflicted with aphids, spider mites and mealybugs all of which can be treated with an application of Neem oil or insecticidal soap.

Resistant to most diseases, kalanchoe is susceptible to root rot. Be sure to use well-draining soil and allow the plant to dry out between waterings.

Pruning & Propagation

The only time you really need to prune kalanchoe is to remove spent blossoms or dead leaves.

Flaming Katy is easy to propagate by stem cuttings or offsets.

To propagate by stem cuttings, simply cut a 2-4 inch (5-10 cm) stem from the plant. Be sure to use a sterile pruner or knife. Remove the lower leaves and allow the cutting to callus by allowing it to dry for a day or so. Plant the callused end into well-draining potting soil, water lightly and wait patiently for root development.

To get another Flaming Katy plant using offsets is even easier. Look for small offsets or “pups” at the base of the plant. Remove the offset by cutting it off with a clean knife. Voila! You have a carbon copy of the parent plant. Follow the instructions as above for callusing the cut end and planting.

Repotting

Flaming Katy is a compact plant, only growing to about 6-12 inches (15-30 cm) both tall and wide. For this reason, repotting is rarely a necessity. However, even if you fertilize regularly during the growing season, most plants can benefit from a boost of fresh soil every couple of years, but it is unlikely that you will need to size up the container.

Varieties

There are approximately 125 species of kalanchoe, mostly originating from Madagascar and tropical regions of Africa. Flaming Katy (K. blossfeldiana) was discovered by Robert Blossfeld in Madagascar in 1926. He brought it to Europe where it rapidly gained popularity as a winter blooming houseplant.

Since then, breeders have expanded the selection of colors available and even introduced hybrids with 32 petals instead of the usual four.
