Kalanchoe Care Tips

Caring for kalanchoe plants is simple as long as you provide them with the right conditions and a little bit of attention. Here are some essential care tips to help your kalanchoe plants thrive:

Light

Kalanchoe plants grown indoors thrive in bright, indirect light.
Outdoor kalanchoes should be planted in partial shade to full sun, with some protection from harsh afternoon sunlight.
Leggy stems indicate a lack of light, so make sure your plant is receiving adequate sunlight.

Soil

Outdoor kalanchoe plants do best in well-draining, loamy or sandy soil.
Indoor plants should be potted in a porous blend, such as a mix of potting soil and cactus mix or potting soil and perlite.
Use a clay pot to ensure proper drainage and prevent root rot.

Water

Kalanchoe plants require minimal water, only needing to be saturated every few weeks.
Allow the soil to dry out completely between waterings to prevent overwatering and root rot.

Temperature and Humidity

Kalanchoe plants thrive in temperatures between 55°F and 80°F.
They are not fussy about humidity levels but prefer a moderate environment.
Protect outdoor kalanchoes from frost, as they are not cold-hardy plants.

Fertilizer

Kalanchoe plants benefit from occasional fertilization, especially during their growth periods.
Use a well-balanced fertilizer blend once a month during the spring and summer, but avoid fertilizing in winter.
If flowering is scarce, switch to a fertilizer higher in phosphorus to encourage blooming.

Growth Rate

Kalanchoe plants are generally slow-growing and can take between two to five years to reach maturity.
Different species have varying growth rates, with some reaching up to 6 feet tall indoors.
Outdoor kalanchoes tend to grow more rapidly due to brighter conditions.

Pruning and Propagating Kalanchoe Plants

To ensure your kalanchoe plants maintain their shape and health, regular pruning and propagating are essential. Follow these tips to keep your plants looking their best:

Pruning

Pinch back the stems of your kalanchoe plant to promote bushier growth and more robust blooming.
Remove any dead flowers during the plant’s resting period in late winter or early spring.

Propagating

Prune and propagate offsets to allow the mother plant to thrive and produce more plants.
You can also take stem cuttings to propagate new kalanchoe plants easily.

Potting and Repotting

Repot your kalanchoe annually in the fall after blooming to encourage new growth.
Increase the pot size gradually with each repotting to promote healthy root growth and plant development.
Use a well-draining potting mix and opt for clay pots to prevent waterlogging.

Overwintering Kalanchoe Plants

In colder climates, overwintering your kalanchoe plants is essential to protect them from frost and cold temperatures. Follow these tips to ensure your plants survive the winter months:

Transition indoor kalanchoes outdoors when the nighttime temperatures are above 60°F.
Bring them back inside when temperatures drop below 55°F to prevent frost damage.
Provide bright, indirect light during the winter months, and water sparingly to prevent overwatering.

How to Get Kalanchoe Plants to Bloom

Achieving a burst of colorful blooms on your kalanchoe plants is an exciting experience. Follow these tips to encourage more blooms and vibrant flowers:

Keeping Kalanchoe Blooming

Ensure your plant receives at least 6 to 8 hours of bright light daily for optimal blooming.
Provide a 14-hour period of darkness each day during the fall and winter to promote flower bud development.
Use a fertilizer high in phosphorus to encourage more blooms if needed.

Encouraging More Blooms

Deadhead spent flowers to promote continuous blooming.
Control the plant’s exposure to light to regulate its blooming cycle effectively.

Necessary Supplies for Blooming
