Caring for a kalanchoe plant is remarkably easy, making it a popular choice for both beginner and experienced plant enthusiasts. With just a few essential tips and the right growing conditions, your kalanchoe, also known as flaming Katy, florists kalanchoe, or Christmas kalanchoe, will thrive and reward you with vibrant blooms. The key to successful Kalanchoe Plant Care lies in understanding its succulent nature and mimicking its native environment.
To ensure your kalanchoe flourishes, remember these fundamental care guidelines: plant it in a well-draining potting mix designed for cacti and succulents, such as a loose, loamy, or sandy medium. Position your kalanchoe in a warm spot indoors where it can receive bright, indirect light, or outdoors in a sunny location that offers some shade from the intense afternoon sun. Crucially, allow the soil to dry out thoroughly between waterings to prevent root rot, a common issue with these plants. During the spring and summer months, a monthly feeding with fertilizer will support healthy growth and flowering for indoor kalanchoes.

Light Requirements for Kalanchoe
Light is a crucial factor in kalanchoe care. When growing kalanchoe indoors, aim for bright, indirect light. For outdoor kalanchoes, partial shade to full sun is suitable, although providing some afternoon shade is beneficial, especially in hotter climates, to prevent leaf scorch. Insufficient light is often indicated by leggy stems, a clear sign that your plant needs more illumination to thrive. Ensuring your kalanchoe receives adequate light is fundamental for robust growth and vibrant flowering.
Best Soil for Kalanchoe Plants
For optimal kalanchoe plant care, choosing the right soil is essential. Outdoors, kalanchoes thrive in well-draining, loamy, or sandy soil. Indoor kalanchoes require a similarly porous and well-draining potting mix. A recommended blend is a 50% potting soil and 50% cactus mix, or alternatively, a 60% potting soil and 40% perlite combination. These mixtures ensure proper drainage, preventing the soil from becoming waterlogged and reducing the risk of root rot.
To further enhance drainage and avoid overwatering, consider planting your kalanchoe in a clay pot. Clay pots are porous and help wick away excess moisture from the soil, creating a drier and healthier environment for your kalanchoe plant.
Watering Your Kalanchoe
Watering is a critical aspect of kalanchoe care, but these succulents are quite drought-tolerant. Kalanchoes prefer to dry out completely between waterings. Typically, saturation every few weeks is sufficient, and even less frequent watering is needed during the winter months when the plant’s growth slows down. Allowing the soil to become completely dry before watering again is key to preventing root rot, a common issue caused by overwatering. Proper watering technique is vital for maintaining a healthy and thriving kalanchoe.
Temperature and Humidity Needs
Temperature and humidity are relatively straightforward aspects of kalanchoe plant care. Generally, kalanchoes flourish in temperatures ranging from 55°F to 80°F (13°C to 27°C). They are not particularly sensitive to humidity levels, making them well-suited to typical indoor environments. Protecting your kalanchoe from frost is the main temperature concern.
As outdoor plants, kalanchoes are only suitable for USDA hardiness zones 10 to 12, as they cannot tolerate prolonged temperatures below 55°F (13°C). In colder zones, they are best enjoyed as indoor plants or seasonal outdoor additions.
Fertilizing Kalanchoe Plants
Like most flowering plants, kalanchoes benefit from regular fertilization, although they are not heavy feeders. For kalanchoes grown in the garden, a single light feeding in the spring is usually sufficient. Indoor kalanchoe plants benefit from monthly fertilization during the spring and summer growing seasons. Use a balanced fertilizer blend to support overall health and blooming. However, refrain from fertilizing during the winter months when the plant is in a period of slower growth. If you notice sparse flowering, consider switching to a fertilizer with a higher phosphorus content, which promotes bloom production.
Kalanchoe Growth Rate and Size
Kalanchoes are known for their slow growth rate, typically taking between two to five years to reach their mature size. The popular ‘Flaming Katy’ variety generally reaches around 12 inches in height at maturity. Other kalanchoe types have different growth habits. Paddle plants ( Kalanchoe thyrsiflora) can grow to over two feet tall, while cathedral bells (Kalanchoe pinnata) and velvet-leaf kalanchoe (Kalanchoe beharensis) can reach impressive heights of 5 or 6 feet when grown indoors.
Kalanchoes grown outdoors tend to exhibit faster growth rates due to the brighter light conditions they receive. Understanding the growth habits of different kalanchoe varieties helps in proper placement and care.

Pruning and Maintenance
Regular pruning is beneficial for kalanchoe plant care. Pinching back the stems helps maintain a compact shape and encourages more abundant blooming. Deadheading spent flowers is also important to keep the plant tidy and stimulate new growth. This is particularly crucial during the plant’s dormant period in late winter and early spring to prepare it for the next blooming cycle.
Common Pests
Keep an eye out for aphids, a common pest that can affect kalanchoe plants, especially as new leaves emerge. Aphids are attracted to young, tender foliage. Regularly inspect the undersides of leaves and remove any aphids you find with a strong spray of water. Early detection and intervention can prevent infestations from becoming severe.
Propagating Your Kalanchoe
Propagating kalanchoe is a rewarding way to expand your collection. Offsets, or small plantlets that grow around the base of the mother plant, can be propagated easily. Additionally, stem cuttings are another effective propagation method. Removing offsets not only provides new plants but also redirects energy back to the mother kalanchoe, promoting its continued growth.
Here’s how to propagate kalanchoe using stem cuttings and offsets:
- Using a clean, sharp knife or clippers, cut a stem segment several inches long from a mature plant. For offsets, gently remove them from the joint where they connect to the parent plant.
- Allow the cuttings to dry out for a few days until the cut ends appear calloused and healed. This prevents rot when planting.
- Dip the calloused ends into rooting hormone powder to encourage faster root development, although this is optional.
- Plant the cuttings in a well-draining soil mix similar to what the mother plant is growing in.
- Place the newly planted cuttings in a location with bright, indirect light and avoid watering initially. Roots should begin to form within a month, after which you can start regular kalanchoe care as you would for a mature plant.
Potting and Repotting Kalanchoe
Unlike some plants that prefer to be root-bound, kalanchoes benefit from regular repotting. Annual repotting in the fall, after the blooming period, is recommended for optimal kalanchoe plant care. Repotting encourages fresh growth and enhances the plant’s overall fullness. Each time you repot, increase the pot size by one increment. However, if the plant’s root system isn’t filling its current pot, you can simply refresh the soil surface layer without changing the pot size.
Always use a pot with good drainage. Clay pots are an excellent choice because their porous nature helps to keep the soil from retaining too much moisture, which is vital for preventing root rot in kalanchoes.
Overwintering Kalanchoe
In regions with cooler climates, indoor kalanchoe plants can be moved outdoors during the warmer months once nighttime temperatures consistently stay above 60°F (15°C). As temperatures begin to drop in late summer or early fall, bring them back indoors. Kalanchoes are susceptible to frost damage and may not survive temperatures below freezing (32°F or 0°C). A safe guideline is to bring them indoors when nighttime temperatures dip below 55°F (13°C).
In USDA hardiness zones 9 through 11, kalanchoe plants might survive a light frost, even if the foliage experiences some dieback. However, in colder climates, frost damage is likely to be fatal.
During the winter months, position your kalanchoe in a bright location with indirect light, such as a south- or west-facing window. If natural light is insufficient, consider using a grow light to supplement. Reduce watering frequency during winter as kalanchoes require less moisture during their dormant period. Allow the soil to dry out thoroughly between waterings.
Moving Kalanchoe Outdoors for the Summer
Once nighttime temperatures consistently exceed 65°F (18°C), you can gradually acclimate your kalanchoe to outdoor conditions. Begin by placing it in a shaded location for a few hours each day, gradually increasing its exposure to sunlight over a week or two. The ideal outdoor spot for kalanchoe is one that receives morning sun and is sheltered from intense afternoon sunlight.
Encouraging Kalanchoe to Bloom
Maintaining Blooms
To maximize blooming in your kalanchoe plant, ensure it receives at least 6 to 8 hours of bright light daily. Crucially, to initiate bud formation, kalanchoes require long periods of darkness. During the fall and winter, provide your kalanchoe with approximately 14 hours of complete darkness each day for at least six weeks. This extended dark period is essential for the plant to accumulate energy for abundant flowering.
Typically, about four months after this dark period, in spring, you can expect a spectacular display of colorful flowers that can last for several weeks. With controlled light exposure, blooms can often reoccur throughout the year. Proper light management is key to year-round kalanchoe blooming indoors. Avoid harsh, direct sunlight, which can sometimes inhibit flowering; bright, indirect light is optimal for consistent blooms.
Promoting More Flowers
Deadheading spent flowers is a simple yet effective way to encourage continuous kalanchoe flowering. Removing faded blooms redirects the plant’s energy into producing new flowers. If your kalanchoe is not blooming as expected, consider using a fertilizer blend that is high in phosphorus. Phosphorus is known to promote bud development and can help stimulate more profuse flowering.
Common Kalanchoe Problems and Solutions
Kalanchoe plants are generally low-maintenance, but certain issues can arise, usually related to improper watering or temperature stress.
Soft, Damaged Blooms and Leaves
Exposure to near-freezing temperatures can result in damaged leaves and stunted or deformed blooms. Maintain temperatures above 50°F (10°C) to prevent cold damage and ensure healthy growth.
Wilting Leaves
Excessively high temperatures can cause kalanchoe leaves to wilt. Ideally, keep temperatures below 80°F (27°C) to avoid heat stress and wilting.
Drab or Burned Leaves
Light exposure is critical for leaf health. Insufficient light can cause leaves to lose their characteristic glossy green color, becoming dull. Conversely, too much direct sunlight can lead to sunburned leaves. Position indoor kalanchoes in a location with bright, indirect light to maintain vibrant foliage without leaf burn.
Soft, Fragile Stems
Overwatering or using a soil mix that retains too much moisture are common causes of soft, fragile stems in kalanchoes. Excess moisture can lead to root and stem rot. If you notice soft stems, immediately reduce watering and allow the soil to dry out completely until the plant recovers.
Failure to Bloom
The most common reason for a kalanchoe not blooming is insufficient winter darkness. Kalanchoes are short-day plants, meaning they require a period of long nights to initiate flowering. Ensure your plant receives at least 14 hours of uninterrupted darkness each day for about six weeks during the fall or winter to reset its bloom cycle and encourage flowering.
