Light Requirements
Kalanchoe exellii Raym.-Hamet prefers bright sunlight or partial shade. Exposing the plant to direct sunlight may scorch its leaves. Therefore, it is best to grow the plant indoors in a location that receives bright, indirect sunlight for at least six hours a day. Outdoor grow sites should be chosen carefully to ensure indirect sunlight and not too much exposure to the sun.
Temperature Requirements
This plant requires warm temperatures between 60°F-90°F (16°C-32°C). Temperatures below 50°F (10°C) can cause the leaves to drop, and the plant won't thrive if left in temperatures below 40°F (4.4°C). It is essential to select a warm indoor location near a window or outdoor area that provides enough protection from extreme weather conditions to ensure the plant's health.
Soil Requirements
The Kalanchoe exellii Raym.-Hamet thrives in well-draining soil with a slightly acidic to neutral pH of 6.0-7.0. Soil amendments, such as perlite or sand, can help improve soil drainage. The plant does best in lightweight, porous soils that promote root growth. A commercially available cactus or succulent potting mix will provide the perfect blend of nutrients and drainage for this plant. Experts recommend also using a terra-cotta container with a drainage hole for optimal plant health.

Propagation Methods for Kalanchoe exellii Raym.-Hamet
Propagation of Kalanchoe exellii Raym.-Hamet is best done during the growing season. This succulent plant can be propagated in several ways:
Leaf Cuttings
One of the easiest methods for propagating Kalanchoe exellii Raym.-Hamet is through leaf cuttings. Simply take a healthy leaf cutting from the parent plant and allow it to callus over for a few days. Then, plant the cutting in well-draining soil and keep it in a bright, indirect location. Within a few weeks, the cutting should start developing roots and forming new plantlets.
Stem Cuttings
Another method of propagation for Kalanchoe exellii Raym.-Hamet is through stem cuttings. Take a cutting from the parent plant's stem and allow the cut end to callus over. Then, plant the cutting in a moist, well-draining soil medium. Keep the cutting in a bright, indirect location and water lightly. Within a few weeks, the cutting should begin to develop roots and form new plantlets.
Offsets
Offsets are small plantlets that develop at the base of the parent plant. They can be carefully removed and potted in well-draining soil to create a new plant. Make sure that the offset has enough roots before separating it from the parent plant. Keep the new plant in a bright, indirect location and water lightly until it becomes established.
Seeds
Propagation through seeds is possible, but it's not the most reliable method of propagation. Seeds can take a long time to germinate and require specific environmental conditions to succeed. If you decide to propagate Kalanchoe exellii Raym.-Hamet through seeds, make sure to use fresh seeds and plant them in a well-draining soil medium. Keep the soil moist and the seeds in a bright location with moderate temperatures until they germinate.
Disease and Pest Management for Kalanchoe exellii Raym.-Hamet
Kalanchoe exellii Raym.-Hamet is generally a healthy plant, but like any other plant, it is susceptible to various diseases and pests. Here are some of the common diseases and pests that might affect the plant and ways to manage them.
Diseases
Phytophthora root rot: This fungal disease can cause wilting, stunting and yellowing of the leaves. It can also cause the roots to rot and turn brown. The best way to manage Phytophthora root rot is to avoid over-watering the plant and improving soil drainage. Fungicides can also help prevent the spread of the disease.
Gray mold: This fungal disease can cause a fuzzy gray growth on the leaves and stems of the plant. It can also cause the leaves to turn yellow and drop. To manage gray mold, you need to remove infected plant parts, maintain good air circulation, and keep the plant dry. Fungicides can also be used, but they are best applied as a preventative measure.
Crown and stem rot: This fungal disease can cause the stems and crowns of the plant to rot. The leaves may also turn yellow and drop. To manage crown and stem rot, you should avoid over-watering the plant, improve soil drainage, and remove infected plant parts. Fungicides can also help prevent the spread of the disease.
Pests
Scale insects: These insects can cause stunted growth, yellowing leaves and a sticky residue on the plant. To manage scale insects, you need to remove them from the plant and apply an insecticidal soap or oil. Repeat the treatment every 7-10 days.
Spider mites: These tiny pests can cause yellowing of the leaves, and in severe cases, they can leave a fine webbing on the plant. To manage spider mites, you should keep the plant moist and misted, especially during dry periods. You can also use an insecticidal soap or oil to control them.
Mealybugs: These small insects can cause distorted growth and yellowing of the leaves. They also leave a white, cottony substance on the plant. To manage mealybugs, you can remove them from the plant and apply an insecticidal soap or oil. Repeat the treatment every 7-10 days.
By following the above measures, you can keep Kalanchoe exellii Raym.-Hamet healthy and vibrant. Regular inspection of the plant can help detect diseases and pests early, allowing you to take appropriate action before they cause significant damage.
