Kalanchoe 101: A Complete Guide to Growing and Caring for Kalanchoes

Kalanchoe, a diverse genus of succulent plants, is prized by both novice and expert gardeners for its vibrant blooms, striking foliage, and easy care needs. With over 200 known species, these plants range from compact, flowering houseplants to dramatic, sculptural garden specimens often thriving with minimal care. This guide provides everything you need to grow, nurture, and enjoy Kalanchoe, indoors or out.

What is Kalanchoe?

Kalanchoe is a genus of succulent plants native primarily to the arid regions of Madagascar and Africa. Famous for abundant clusters of small, long-lasting flowers and thick, fleshy leaves that store water, these plants belong to the Crassulaceae family. They have gained popularity worldwide as low-maintenance houseplants and are also used in beds, borders, rock gardens, and beyond.

Main Kalanchoe Features

• Thick, water-storing leaves characteristic of succulents
• Wide range of flower colors: red, orange, pink, yellow, white
• Many varieties flower through winter to spring
• Adaptable to various indoor and outdoor conditions
• Low water and maintenance requirements
• Can be propagated easily from cuttings or offsets

Popular Kalanchoe Varieties

Choosing the Right Location

Kalanchoe thrives in bright light but has a degree of flexibility. For the best results:

• Indoors: Place near a south or east-facing window where it receives 6-8 hours of indirect sunlight daily. Avoid intense direct sun that can scorch leaves.
• Outdoors: Grow in spots with full sun to partial shade, especially in warmer climates. Protect from strong afternoon sun in hot regions.

If planting outdoors, ensure the risk of frost has passed. Kalanchoe generally does well in USDA Zones 9–12, depending on the variety.

Soil and Potting Requirements

• Use a porous, well-draining succulent/cactus soil mix; you can make your own by combining equal parts potting soil, coarse sand, and perlite.
• Always use containers with drainage holes to prevent waterlogging and root rot.
• For outdoor beds, loosen and amend the soil with sand or perlite to improve drainage if needed.
• Maintain a soil pH between 6.5 and 7.5 for optimal growth.

Watering Your Kalanchoe

Water needs are low. Allow the soil to dry out between waterings:

• Water thoroughly, then wait until the top inch (2.5 cm) of soil is dry before watering again.
• Overwatering is the most common cause of issues—avoid soggy soil at all costs.
• Decrease frequency during the winter when the plant is resting.

Fertilization

• Fertilize sparingly—a diluted, balanced liquid fertilizer applied once a month during the active growing season (spring and summer) is sufficient.
• No fertilizer is needed during fall and winter, when the plant is dormant.

Temperature and Humidity

• Temperatures: 60–85°F (16–29°C) are ideal.
• Keep above 50°F (10°C).
• Humidity: Prefers dry air but adapts to average household humidity.
• If overwintering indoors, avoid drafty windowsills and sudden temperature drops.

Flowering and Reblooming

Kalanchoes are known for their brilliant, long-lasting flowers. Most varieties, especially K. blossfeldiana, bloom in winter or early spring.

• Inducing blooms: These plants need short nights and long days (at least 14 hours of darkness per day for 4–6 weeks) to initiate flower buds. Cover with a box or move to a dark spot each evening to trigger seasonal blooms.
• After blooming, allow the plant to rest by reducing water and withholding fertilizer until next cycle.

Propagating Kalanchoe

Propagation is a straightforward process thanks to the plant’s succulent nature and ability to grow from a variety of cuttings. Here’s how you can multiply your collection:

Leaf Cuttings

• Choose a healthy stem 4–6 inches long; cut below a node.
• Remove lower leaves, leaving 2–3 at the top.
• Let the cutting dry and callous for 1–2 days.
• Plant in a small pot with succulent soil.
• Place in a warm, bright area with indirect light.
• Water sparingly; roots usually form within 2–3 weeks.

Offshoot Removal and Division

• Look for small plantlets at the base of mature plants or along leaf edges (for species like K. daigremontiana).
• Gently remove offsets with some roots attached.
• Repot separately into pots with drainage; water lightly.
• Division can also be done by carefully splitting the root ball of a larger plant.

Repotting and Transplanting

• Repot when roots are crowded or soil degrades—typically every 2–3 years.
• Choose a slightly larger container with excellent drainage.
• Gently remove plant, shake off excess soil, and inspect the roots. Trim any dead or damaged roots.

Common Pests, Diseases, and Problems

• Pests: Watch for mealybugs, scale, and spider mites. Treat infestations by wiping with isopropyl alcohol or using insecticidal soap.
• Diseases: Most issues stem from overwatering: leaf spot, powdery mildew, and especially root rot. Ensure soil dries between waterings and never let the plant sit in water.
• Other Issues: Pale, etiolated (stretched) growth signals insufficient light.

Landscaping and Decorative Uses

• Indoors: Kalanchoe makes a striking focal point in containers on windowsills, kitchen tables, and desks. Compact forms are ideal for terrariums, centerpieces, and office décor.
• Outdoors: Perfect for garden beds, borders, rock gardens, and xeriscaping. Pair with other succulents or drought-tolerant species for year-round interest.
• Flower arrangements: Long-lasting blooms enhance bouquets and fresh arrangements.

Frequently Asked Questions (FAQs)

Q: How often should I water my Kalanchoe?

A: Let the soil dry between waterings, usually every 1–2 weeks depending on indoor climate and container size. Avoid letting the plant sit in water.

Q: Why isn’t my Kalanchoe blooming?

A: Lack of blooms is often due to insufficient light or not providing a period of extended darkness. Give your plant at least 14 hours of uninterrupted darkness each night for 4–6 weeks to trigger bloom set.

Q: Can Kalanchoe be grown outdoors in cold climates?

A: Only in frost-free regions (Zones 9–12). In cooler areas, grow Kalanchoe as a summer annual or bring indoors before frost.

Q: Is Kalanchoe toxic to pets?

A: Yes, all parts are toxic to cats and dogs if ingested, causing stomach upset and other symptoms. Keep out of reach of pets.

Q: What’s the best way to propagate Kalanchoe?

A: Use leaf or stem cuttings, allowing cut edges to callous before planting in moist, well-draining soil. Offsets at the base or along leaves can also be separated and potted individually.

Expert Tips for Growing Kalanchoe

• Rotate indoor pots every few weeks for even growth.
• Remove spent blooms to encourage new flowers and keep the plant tidy.
• Use clay or terracotta pots to help excess moisture evaporate.
• Don’t hesitate to prune leggy stems for a bushier plant.
• Pair with other drought-tolerant species in mixed arrangements for dynamic texture and color contrast.

Final Thoughts

With their eye-catching blooms, water-wise habit, and adaptable nature, Kalanchoe succulents are an excellent choice for any gardener. Whether grown as cheerful houseplants or dazzling accents in the landscape, these plants reward minimal effort with months of color and architectural interest—making them a true staple of the succulent world.
