Kalanchoe, a stunning succulent with vibrant flowers, is beloved for its beauty and low-maintenance care. While many treat it as a one-season plant, kalanchoe can rebloom multiple times with the right techniques. If you’ve ever wondered how to get your kalanchoe to bloom again and again, this comprehensive guide will provide all the steps you need to keep your plant thriving for years.
Why Choose Kalanchoe?
Kalanchoe is a popular choice for both indoor and outdoor gardening due to its:
- Long-lasting blooms: Flowers can last for weeks or even months.
- Low water requirements: Perfect for busy or forgetful gardeners.
- Attractive foliage: Even without flowers, its glossy green leaves make it a beautiful decorative plant.
- Compact size: Ideal for small spaces, windowsills, or desks.
With a little care and attention, your kalanchoe can transition from a seasonal plant to a long-term companion in your garden or home.
Understanding Kalanchoe’s Blooming Cycle
To encourage reblooming, it’s essential to understand the natural growth cycle of kalanchoe:
- Active Growth Phase: This occurs after the flowering period, when the plant focuses on growing leaves and stems.
- Dormant Phase: Typically starting in late fall or early winter, the plant rests and prepares for its next bloom.
- Reblooming Phase: With proper care, kalanchoe will produce new buds and vibrant flowers, often by late winter or early spring.
Proper timing and adjustments during each phase are key to triggering blooms.
Steps to Make Your Kalanchoe Rebloom
1. Repot After Flowering
Once your kalanchoe finishes blooming, it’s time to repot:
- Choose a slightly larger pot to allow for growth.
- Use a well-draining soil mix rich in humus, combined with sand or gravel to mimic the plant’s natural habitat.
- Ensure the pot has drainage holes to prevent waterlogging, which can cause root rot.
Repotting not only provides fresh nutrients but also gives the roots space to expand, supporting a healthier plant.
2. Prune for a Compact Shape and New Buds
After flowering, prune the plant to encourage new growth:
- Trim the stems back by about half, focusing on removing any leggy or weak growth.
- Pinch off dead flowers to prevent the plant from wasting energy on seed production.
This process helps the kalanchoe maintain a bushy, compact shape and stimulates the formation of flower buds.
3. Create a Dark Period
Kalanchoe is a short-day plant, meaning it requires extended periods of darkness to trigger blooming:
- Starting in November, place the plant in complete darkness for 12-14 hours daily.
- Use a cardboard box to cover it or move it to a dark room without light from 6 p.m. to 7 a.m.
During the day, ensure the plant receives bright, indirect sunlight for optimal growth. Consistency in this routine is crucial for encouraging flower production.
4. Control Temperature for Dormancy
Temperature plays a significant role in the kalanchoe’s blooming cycle:
- Maintain a cool environment of 10-15°C (50-59°F) during the dormant phase.
- Avoid temperatures below 9°C (48°F), as they can damage the plant.
Cooler temperatures signal the plant to rest and prepare for its next bloom cycle.
5. Adjust Watering Schedule
Kalanchoe is drought-tolerant and prefers dry conditions during its dormant phase:
- Water sparingly from November until buds appear. Allow the soil to dry out between waterings.
- Avoid overwatering, which can lead to root rot and fungal diseases.
Once buds form, gradually increase watering to support flower development.
6. Skip Fertilizing During Dormancy
Fertilizer can overstimulate growth and delay blooming:
- Refrain from feeding the plant during the dormant phase.
- Once buds appear, resume fertilizing with a balanced houseplant fertilizer every 4-6 weeks to support healthy blooms.
Troubleshooting: Why Isn’t My Kalanchoe Blooming?
If your kalanchoe isn’t reblooming despite your efforts, consider these potential issues:
- Insufficient Darkness: Even a small amount of light during the dark period can disrupt the blooming cycle.
- Improper Pruning: Failure to prune after flowering can result in weak or sparse growth.
- Overwatering: Too much water during dormancy can lead to root rot and prevent flower formation.
- Age of the Plant: Older kalanchoe plants may lose vigor over time. Propagating new plants can rejuvenate your collection.
How to Propagate Kalanchoe for a Fresh Start
Propagation is an excellent way to ensure you always have healthy, blooming kalanchoe plants. Here’s how:
- Choose Healthy Cuttings: Select a 3-4 inch stem with at least two sets of leaves.
- Dry the Cutting: Let the cutting dry for 24-48 hours to form a callus.
- Plant in Well-Draining Soil: Place the cutting in moist, sandy soil.
- Provide Indirect Light: Keep the cutting in a bright spot away from direct sunlight.
- Water Sparingly: Water lightly until roots form, usually within 2-3 weeks.
Once established, the new plant will follow the same blooming cycle as its parent.
Enjoying Your Reblooming Kalanchoe
With proper care and patience, your kalanchoe can bloom multiple times a year, filling your home with vibrant colors and cheerful energy. Watching your plant rebloom is not only satisfying but also a testament to your gardening skills.
