  4. Sowing seeds: Fill small seed trays or pots with the seed starting mix. Sprinkle the Kalanchoe seeds on top of the soil and lightly press them down. It’s important not to bury the seeds too deeply as they need light to germinate.
  5. Moisture and covering: Mist the soil lightly to moisten it without soaking. Cover the seed trays or pots with a plastic dome or place them inside a clear plastic bag to create a humid environment. This helps retain moisture and speeds up germination.
  6. Germination conditions: Place the seed trays or pots in a warm location with bright, indirect light. Kalanchoe seeds typically require temperatures around 70°F to 75°F (21°C to 24°C) for successful germination.
  7. Germination period: Kalanchoe seeds can take anywhere from one to three weeks to germinate. During this time, check the moisture levels regularly and mist the soil as needed to keep it lightly moist but not overly wet.
  8. Transplanting: Once the seedlings have developed a few sets of true leaves and are large enough to handle, gently transplant them into individual pots filled with a well-draining succulent or cactus potting mix. Keep them in a warm and well-lit location.
  9. Care and growth: As the seedlings grow, continue to provide them with bright, indirect light and maintain appropriate moisture levels. Be careful not to overwater, as Kalanchoe seedlings are susceptible to root rot. Gradually acclimate them to more direct sunlight over time.
  10. Plant maturity: It takes time for Kalanchoe seedlings to grow into mature plants. As they develop, continue to provide proper care, including regular watering when the soil has dried out, fertilizing with a diluted succulent fertilizer every few months, and ensuring they have adequate light.

Growing Kalanchoe from seeds requires patience and attention to detail. Not all seeds may germinate, but with proper care and conditions, you can successfully grow new Kalanchoe plants from seeds.

How to Get Kalanchoe to Bloom

To encourage Kalanchoe plants to bloom, there are a few key factors to consider:

  1. Light: Kalanchoe plants require ample sunlight to trigger blooming. Place your plant in a bright location where it can receive indirect sunlight for at least six hours a day. A south-facing window is often ideal. However, be cautious about exposing the plant to intense, direct sunlight, as it can scorch the leaves.
  2. Daylight Duration: Kalanchoe plants are photoperiodic, which means they rely on specific day lengths to initiate flowering. To induce blooming, provide the plant with shorter daylight hours. About six to eight weeks before you desire the blooms, reduce the daily exposure to light by placing the plant in a dark room or covering it with a box for 14-16 hours a day. Maintain this reduced light period consistently throughout the specified duration.
  3. Temperature: Kalanchoe plants typically prefer moderate temperatures between 60°F and 85°F (15°C and 29°C). Avoid exposing them to extreme cold or hot temperatures, as it can affect flowering. Consistent temperature conditions are more conducive to blooming.
  4. Watering: Proper watering practices are important for overall plant health and blooming. Avoid overwatering, as it can lead to root rot. Allow the soil to dry out slightly between waterings, and always water thoroughly, ensuring excess water drains away. Maintaining a balanced moisture level helps promote flowering.
  5. Fertilization: Use a balanced, water-soluble fertilizer formulated for succulents or cacti during the active growing season. Follow the instructions on the fertilizer package for the recommended application rate and frequency. Be cautious not to over-fertilize, as it may result in excessive foliage growth instead of blooms.
  6. Rest Period: After the blooming period, Kalanchoe plants require a rest period to recover and prepare for future flowering. Reduce watering and provide less fertilizer during this time. Keep the plant in a cooler location with reduced light exposure for about a month to allow it to rest.

By following these tips and maintaining consistent care, you can help stimulate blooming in your Kalanchoe plants and enjoy their colorful and vibrant flowers.

Common Problems With Kalanchoe

While Kalanchoe plants are generally hardy and relatively low-maintenance, they can still face a few common problems. Here are some issues you may encounter with Kalanchoe and suggestions on how to address them:

  1. Overwatering: Excessive watering can lead to root rot and other fungal diseases. To prevent this, allow the soil to dry out slightly between waterings. Ensure proper drainage by using well-draining soil and pots with drainage holes. If you notice signs of overwatering, such as yellowing leaves or wilting, adjust your watering routine and let the soil dry out more thoroughly.
  2. Underwatering: On the other hand, underwatering can cause wilting, shriveled leaves, and stunted growth. Check the soil regularly and water the plant thoroughly when the top inch of soil feels dry. Ensure the water reaches the roots and allow any excess to drain away. Consider the environmental conditions, such as temperature and humidity, as they can affect the plant’s water needs.
  3. Powdery Mildew: Powdery mildew is a fungal disease that appears as a white, powdery coating on the leaves and stems. It can occur in conditions of high humidity or poor air circulation. To prevent powdery mildew, ensure adequate airflow around the plant, avoid overcrowding, and maintain moderate humidity levels. If the disease appears, treat it with a fungicidal spray formulated for powdery mildew.
  4. Root Rot: Root rot is caused by overwatering and poorly draining soil. It results in black, mushy roots and can lead to the plant’s decline. To prevent root rot, use a well-draining soil mix and pots with drainage holes. Water the plant appropriately, allowing the soil to dry out between waterings. If root rot is detected, remove the affected parts of the plant and repot it in fresh, well-draining soil.
  5. Pest Infestations: Kalanchoe plants can be susceptible to common houseplant pests, such as mealybugs and aphids. Regularly inspect your plant for signs of pests, such as small insects, sticky residue, or distorted leaves. If infestations occur, treat them with insecticidal soap or horticultural oil, following the product instructions. Isolating the affected plant from other healthy plants can help prevent the spread of pests.
  6. Leaf Drop: Environmental stressors, such as sudden temperature changes, drafts, or inadequate light, can cause Kalanchoe plants to drop their leaves. Ensure consistent temperature conditions, protect the plant from drafts, and provide it with sufficient bright, indirect light. If the leaf drop continues despite optimal conditions, consider other factors such as overwatering or nutrient deficiencies.

By addressing these common problems promptly and providing the proper care, you can help maintain the health and vitality of your Kalanchoe plants.
