- Ask Questions: Don’t hesitate to ask the seller about the plant’s origin, age, and any care tips they might have.
How to Care for Kalanchoe
Looking after Kalanchoe plants can be enjoyable, but it’s important to know what they need. Originally from dry areas in Madagascar, these tough succulents have beautiful flowers and leaves if you take care of them well. Here are the simple steps to keep your Kalanchoe healthy, from where to grow them to how to look after them properly.
Lighting Needs
- Indirect Sunlight: Kalanchoe plants require plenty of bright, indirect sunlight to flourish. Direct sunlight can scorch their leaves, while insufficient light can lead to leggy growth and sparse blooming.
- Ideal Indoor Location: A spot near an east or west-facing window is ideal, where the plant can enjoy the morning or late afternoon sun without the harsh midday rays.
- Outdoor Growing: If you’re growing Kalanchoe outdoors, choose a location that receives partial sun, with protection from the intense afternoon sunlight. Morning sun and afternoon shade typically provide the best balance.
Watering and Soil Requirements
- Watering Schedule: Kalanchoes are drought-tolerant and prone to overwatering. Water them only when the top inch of the soil is dry to the touch. During the winter months, reduce watering as the plant goes into a dormant state.
- Soil Type: A well-draining soil mix is vital for preventing root rot. A mix designed for cacti and succulents, which typically includes components like perlite or sand, is ideal. This ensures quick drainage and prevents moisture from lingering too long around the roots.
- Pots with Drainage: Ensure your Kalanchoe is planted in a pot with adequate drainage holes. This allows excess water to escape, keeping the soil environment balanced.
Temperature and Humidity
- Temperature Range: Kalanchoes thrive between 60-85°F (15-29°C). They are not frost-hardy, so protecting them from cold drafts and temperatures below 50°F (10°C) is important.
- Avoiding Temperature Extremes: Sudden temperature changes can stress these plants. Keep them away from heating vents in winter and air conditioning vents in summer.
- Humidity Levels: Moderate humidity levels are ideal for Kalanchoe. While they can tolerate lower humidity levels, extremely dry air can lead to desiccation of leaves. In very dry environments, a small room humidifier can be beneficial, or placing the pot on a tray filled with pebbles and water can help increase humidity around the plant.
Pruning and Deadheading
- Purpose of Pruning: Pruning is essential for maintaining the desired shape and size of your Kalanchoe. It helps in removing any leggy or spindly growth, encouraging the plant to become bushier and more compact.
- How to Prune: Use clean, sharp scissors or pruning shears. Cut back any elongated stems, being careful not to remove more than one-third of the plant at a time. This can be done anytime the plant looks untidy or overgrown.
- Deadheading: Removing spent flowers, or deadheading, is crucial for promoting more blooms. Once the flowers fade, snip them off at the base of the flower stem. This encourages the plant to focus its energy on new growth and future blooming.
Fertilising and Repotting
- Fertilising Schedule: Kalanchoe benefits from regular fertilisation during the growing season (spring and summer). A balanced, water-soluble fertiliser, diluted to half the recommended strength, should be applied every 4-6 weeks.
- Avoid Over-fertilising: Excessive fertiliser can harm the plant, leading to salt buildup in the soil and potential leaf burn.
- Repotting Needs: Kalanchoes typically need to be repotted every two years. Choose a pot that is one size larger than the current one. Repotting provides the plant with fresh soil and more room to grow.
- Repotting Process: Gently remove the plant from its current pot, shake off the old soil, and check the roots for any signs of rot or disease. Please place it in the new pot with fresh, well-draining soil and water lightly.
Pest and Disease Management
- Common Pests: Kalanchoes can attract pests like aphids, mealybugs, and spider mites. These pests usually appear on the undersides of leaves or at the stem joints.
- Disease Watch: Be on the lookout for signs of powdery mildew or fungal infections, which can be caused by excessive moisture or poor air circulation.
- Preventive Measures: Ensure good air circulation around the plant, avoid overwatering, and keep the leaves dry to prevent fungal diseases.
- Treatment: If pests or diseases are detected, treat them promptly. Insecticidal soap or neem oil can be effective against pests. Fungal infections can be treated with appropriate fungicides. Always follow the instructions carefully when using any treatment products.
Propagating Kalanchoe
Propagation of Kalanchoe is a straightforward and rewarding process that allows you to create new plants from existing ones. Whether you want to share your Kalanchoe with friends or expand your collection, here’s a step-by-step guide on how to propagate Kalanchoe using leaf or stem cuttings:
Selecting Healthy Parent Plant:
Choose a healthy Kalanchoe plant with vibrant leaves and no signs of disease or stress. Healthy parent plants yield better propagations.
Gather Materials:
- Clean, sharp scissors or pruning shears
- Small pots or containers with drainage holes
- Well-draining potting mix (cactus or succulent mix works well)
- Rooting hormone (optional, but can enhance rooting success)
Taking Leaf Cuttings:
- Using clean, sharp scissors or pruning shears, snip off a healthy leaf from the parent plant. Choose a mature leaf; young leaves may not root as successfully.
- Let the leaf-cutting sit in a shaded, dry location for a day or two to allow the cut end to callus. This helps prevent rot when the cutting is planted.
Planting Leaf Cuttings:
- Fill small pots with a well-draining potting mix.
- Plant the calloused end of the leaf, cutting about an inch (2.5 cm) deep in the soil. You can use rooting hormone on the cut end before planting to encourage root growth.
- Water the cutting lightly to settle the soil around it.
Taking Stem Cuttings:
- Alternatively, you can take stem cuttings. Snip off a healthy stem segment that is a few inches long. Ensure it has several leaves attached.
- Let the cut end dry and callus for a day or two.
Planting Stem Cuttings:
- Plant the calloused end of the stem cutting in the potting mix, burying it about an inch (2.5 cm) deep.
- Water lightly to settle the soil.
Caring for Cuttings:
- Place the pots with the leaf or stem cuttings in a bright, indirect light location. Avoid direct sunlight, as it can scorch the cuttings.
- Water sparingly, keeping the soil lightly moist but not soggy. Overwatering can lead to rot.
- Covering the cuttings with a plastic bag or a clear plastic lid can create a mini greenhouse effect, helping to maintain humidity and encourage root growth.
Root Development:
- Root development can take a few weeks to a couple of months, depending on environmental conditions and the type of cutting.
- You’ll know the cuttings have rooted when they start producing new growth.
Transplanting:
- Once the cuttings have developed roots and new growth, they can be transplanted into individual pots or your garden.
