This plant prefers warm temperatures and should be kept in an environment where the temperature stays between 60-85°F (15-29°C). The plant will not tolerate frost, so it should be kept indoors during the winter months in colder regions.
Soil Requirements
The ideal soil for Kalanchoe integra var. crenata is well-draining and rich in nutrients. A mix of potting soil and sand or perlite will provide the perfect growing medium. The plant prefers a slightly acidic soil with a pH between 6.0-7.0. Overwatering or poorly-draining soil can lead to root rot.
Cultivation
Kalanchoe integra var. crenata is a succulent plant that is native to Madagascar and thrives in warm, dry conditions. It requires full sunlight to grow properly and should be planted in well-draining soil that is rich in nutrients.
When planting, ensure that the soil is loosened to allow for proper root growth and water the newly planted cutting only when the soil is completely dry. This will prevent root rot and other fungal diseases that could harm the plant.
Watering Needs
Kalanchoe integra var. crenata does not require frequent watering and can tolerate drought well. The plant should be watered only when the soil is completely dry, with watering frequency decreasing during the winter months.
The best way to ensure proper watering is to use the "soak and dry" method. This involves fully soaking the soil and allowing it to dry out completely before watering again. Avoid over-watering, as this can lead to root rot and other issues.
Fertilization
Kalanchoe integra var. crenata does not require a lot of fertilizer and can grow well with minimal feeding. However, a balanced fertilizer can be applied every two to three months during the growing season to encourage healthy growth.
Be careful not to over-fertilize, as this can damage the plant. Always follow the manufacturer's instructions when applying fertilizer and use a weak solution to avoid damaging the plant.
Pruning
Kalanchoe integra var. crenata does not require frequent pruning, but it can benefit from occasional shaping to encourage bushier growth. Pruning can be done by removing any dead or damaged leaves or cutting back overgrown stems.
Always use clean, sharp pruning shears to prevent damage to the plant and regularly disinfect the blades before use to prevent the spread of disease. Pruning can be done at any time of the year, but it is best to do it during the spring growth period when the plant is in an active growth phase.

Kalanchoe integra (Medik.) Kuntze var. crenata (Andr.) Cufod., commonly known as the "Crenate Kalanchoe," is a popular succulent species native to Madagascar. This plant is primarily propagated through stem cuttings and leaf cuttings.
Stem cutting propagation
The stem cutting method is one of the easiest ways to propagate Kalanchoe integra var. crenata plants. Follow these steps to propagate Kalanchoe integra var. crenata through stem cuttings:
- Identify a healthy stem, preferably one that's at least three inches long.
- Cut the stem off using a sharp and sterilized pruning shear.
- Remove the leaves from the lower half of the stem, leaving only the top leaves.
- Place the stem cutting on a dry surface, in a shaded location, for a couple of days to allow the cut end to dry and form a callus.
- Once the cut end has formed a callus, plant the stem cutting in a well-draining potting mix.
- Water the newly planted cutting and keep it in a location that receives bright but indirect sunlight.
- After a few weeks, the cutting should start producing new growth, which is an indication that the propagation was successful.
Leaf cutting propagation
The leaf cutting method is another viable technique for propagating Kalanchoe integra var. crenata plants. Below are the steps for propagating Kalanchoe integra var. crenata through leaf cuttings:
- Identify a healthy leaf that's plump and fully mature.
- Using a sterilized knife, cut the leaf off the mother plant.
- Allow the cut end to dry and form a callus for a couple of days.
- Plant the leaf cutting in a well-draining potting mix, with the cut end facing downwards and the upper part of the leaf facing upwards.
- Water the newly planted leaf cutting and keep it in a location that receives bright but indirect sunlight.
- After a few weeks, the leaf cutting should start producing new growth, which is an indication that the propagation was successful.
Propagation of Kalanchoe integra var. crenata through stem cuttings and leaf cuttings is relatively easy and has a high rate of success. With the right care and attention, you should have a healthy and thriving new plant in no time.
Disease and Pest Management for Kalanchoe integra var. crenata
Kalanchoe integra var. crenata, also known as the "scalloped-leaf" kalanchoe, is a popular succulent plant that is prized for its beautiful foliage and easy-to-care-for nature. However, like all plants, it is susceptible to certain diseases and pests that can harm its overall health and appearance. Here are some common diseases and pests that might affect your kalanchoe and how to manage them.
Common Diseases
1. Root Rot: This is a condition caused by overwatering or poorly-draining soil. Symptoms include wilting leaves, yellowing foliage, and a slimy or rotten smell. To manage this disease, it is crucial to remove any affected areas of your kalanchoe's roots and repot the plant in fresh soil. Additionally, it is advisable to reduce your watering frequency to prevent further issues. 2. Leaf Spot: This disease is caused by fungi that thrive in humid and moist conditions. Symptoms include brown spots and discoloration on leaves, which can cause the plant's foliage to die. To manage this disease, it is important to remove any affected leaves and treat the plant with fungicides to prevent the disease from spreading. 3. Powdery Mildew: This is a common fungal disease that affects many types of plants in humid conditions. Symptoms include white, powdery spots on the foliage, which can lead to overall plant decline. To manage powdery mildew, it is important to remove any affected leaves and increase air circulation around your plant to reduce humidity levels. Additionally, treating the plant with fungicides can also help.
Common Pests
1. Spider Mites: These tiny pests can cause visible damage to your kalanchoe's leaves, such as yellowing and mottling. To manage spider mites, use a steady stream of water to knock them off the plant's foliage and then treat the plant with insecticides or neem oil to prevent reinfestation. 2. Mealybugs: Mealybugs are small, white insects that can damage your kalanchoe's foliage, causing wilting and yellowing. To manage mealybugs, use a cotton swab dipped in rubbing alcohol to remove them from the plant's leaves and branches. Repeat this process until all visible mealybugs are gone. 3. Aphids: Also known as plant lice, aphids can cause significant damage to your kalanchoe's leaves if left untreated. Symptoms include yellowing foliage and the presence of a sticky substance on the plant's leaves. To manage aphids, use insecticidal soap to target the affected areas of the plant and kill the pests.
Conclusion
Kalanchoe integra var. crenata is a relatively hardy succulent plant that is easy to care for with the right precautions. By implementing these pest and disease management strategies, you can ensure that your plant stays healthy and beautiful for years to come.
