- Outdoors: Kalanchoe thrives in partial shade to full sun. If exposed to direct sunlight, ensure some afternoon shade to avoid leaf scorching.
2. Soil Requirements
- Use well-draining soil, such as a cactus mix or a blend of 50% potting soil and 50% perlite.
- Clay pots are recommended for improved drainage, preventing root rot.
3. Watering Guidelines
- Water Kalanchoe sparingly, allowing the soil to dry out completely between waterings.
- In winter, reduce watering even further to prevent overwatering.
4. Temperature and Humidity
- Ideal temperatures range between 55°F and 80°F (13°C – 27°C).
- Protect Kalanchoe plants from frost by bringing them indoors when temperatures drop below 55°F.
- Kalanchoes are not sensitive to humidity, making them versatile indoor plants.
5. Fertilization
- Fertilize indoor Kalanchoe plants once a month during spring and summer with a balanced fertilizer.
- If flowering is sparse, switch to a phosphorus-rich fertilizer to encourage blooming.
Pruning and Maintenance
- Regular pruning helps maintain the plant’s shape and encourages new growth.
- Deadhead spent flowers to prolong the blooming period.
- Pinch back leggy stems to promote bushier growth.
Propagation Methods
Kalanchoes are easy to propagate, allowing you to expand your collection effortlessly.
Propagation by Stem Cuttings:
- Cut a healthy stem several inches long.
- Let the cutting dry and form a callous for 2-3 days.
- Dip the calloused end in rooting hormone (optional) and plant it in well-draining soil.
- Place the cutting in bright, indirect light without watering until roots develop.
Propagation by Offsets:
- Identify small offsets growing at the base of the mother plant.
- Gently detach the offsets and plant them in fresh soil.
- Water sparingly until new growth appears.
Potting and Repotting Kalanchoe Plants
- Repot Kalanchoe plants annually in the fall after blooming.
- Increase the container size only by one step to prevent excess soil moisture.
- Clay pots are ideal as they promote airflow and drainage.
How to Encourage Blooming
To ensure vibrant blooms, follow these steps:
- Provide 6-8 hours of bright light daily.
- During fall and winter, Kalanchoe requires 14 hours of complete darkness for six weeks to stimulate blooming.
- Deadhead spent flowers and apply phosphorus-rich fertilizer to boost flower production.

- Soft or Damaged Leaves:
- Cause: Exposure to freezing temperatures.
- Solution: Keep Kalanchoe indoors if temperatures fall below 55°F.
- Wilting:
- Cause: Excessive heat (above 80°F).
- Solution: Relocate your plant to a cooler area.
- Drab or Burned Leaves:
- Cause: Too little or too much sunlight.
- Solution: Adjust light exposure to provide bright, indirect light.
