When growing the plant indoors, make sure to keep it away from any cold drafts and maintain a constant room temperature.
Soil Requirements
Kalanchoe humbertii Guillaumin requires well-draining soil with a pH of 6.0 to 7.5. The soil texture should be light and porous, allowing for proper air circulation. A good soil mix can be made by combining peat moss, perlite, and coarse sand in equal parts. Adding organic matter to the soil helps improve its fertility, drainage, and water-holding capacity.
Cultivation methods
Kalanchoe humbertii Guillaumin is an easy-to-care-for plant that requires minimal attention. The plant is not frost-tolerant and thrives well in bright light. It is best to keep the plant in well-draining soil with at least 30% of sand content to improve drainage. A planting mix consisting of 50% standard potting soil and 50% coarse sand is ideal for the plant’s growth.
Kalanchoe humbertii Guillaumin can be propagated by stem cuttings or from leaves, and the best time to propagate the plant is during the early stages of growth in the spring or summer. The plant responds well to gentle tugs, grew taller if in a shaded area, and had fewer flowers.
Watering needs
Kalanchoe humbertii Guillaumin is drought-tolerant but needs moderate watering. Over-watering can lead to root damage and cause the plant to rot. Experts recommend watering the plant once a week and allowing the soil to dry out between watering sessions. During the winter, the plant requires less water because of the colder temperatures and shorter days. If in doubt, carefully dig through the soil to check for dryness before watering.
Fertilization
Kalanchoe humbertii Guillaumin does not require frequent fertilization. Fertilizing once every two months, preferably in the spring and summer, with a balanced fertilizer mixed to half strength will work well for the plant’s growth. Overfeeding the plant can cause root burn.
Pruning
It is best to prune Kalanchoe humbertii Guillaumin after blooming to encourage more growth and produce a bushier plant. The plant loses its leaves periodically, but they tend to grow back quickly. Dead, brown, or yellow leaves should be removed promptly as they can harbor diseases and attract pests. The plant's size can also be controlled by cutting back on its branches to encourage bushiness.
Propagation of Kalanchoe humbertii Guillaumin
Kalanchoe humbertii Guillaumin can be easily propagated from stem cuttings. The best time to take cuttings is during the active growth period, which is in spring and summer. To propagate the plant, select a healthy stem that has no visible diseases or signs of stress.
Stem Cuttings Propagation
Take a stem cutting that is at least 4-6 inches long, and remove the leaves from the bottom half of the stem. Dip the cut end of the stem in rooting hormone. Then, plant the cutting in a pot with a well-draining soil mix. Water the cutting and keep it in a warm and bright spot, but not in direct sunlight.
After a few weeks, the cutting should have roots and will start to develop new leaves. Once the plant has well-developed roots, it can be transplanted into a larger pot or directly into the garden.
Division Propagation
Kalanchoe humbertii Guillaumin can also be propagated by division. This method is best suited for mature plants that have several offsets growing at the base. Carefully separate the offsets from the mother plant, taking care not to damage their roots. Plant each offset in its own pot, or directly in the garden.
Water the newly propagated plants regularly, but avoid over-watering as this can cause rot. With proper care, the new plants should establish quickly, and you will soon have a collection of Kalanchoe humbertii Guillaumin to enjoy.
