Expert tips
The key tip
Water very sparingly: wait for the substrate to be completely dry before watering again. The trap is winter overwatering (it rots before freezing).
The common mistake
Keeping the soil moist "to be safe" — it dies from root suffocation long before drought strikes.
The pro's trick
Mix coarse sand or pumice into the potting mix to improve drainage.
Seasonal watch
September-November: cut back watering significantly before the first frost, otherwise it freezes in waterlogged soil.
Care
Watering
Water moderately during the growing season (spring-summer), letting the substrate dry out well between waterings. In autumn and winter, drastically reduce watering or suspend it altogether. Kalanchoes store water in their leaves and fear excess moisture and root rot.
Light exposure
Place this succulent in full sun, at least 6 hours per day, to ensure attractive growth and abundant flowering. It tolerates a few hours of indirect light, but lacking brightness, it will become leggy and its leaves will lose their colour.
Substrate and drainage
Use a very well-draining mix made up of cactus compost, coarse sand and perlite in equal parts. The pot must have a drainage hole. Kalanchoes do not tolerate heavy or constantly moist soils.
Pruning and pinching
Pinch young stems to encourage compact, bushy branching. After flowering, you can remove faded stems to maintain a neat shape. Light pruning in late winter prepares the plant to regrow vigorously in spring.
Feeding
Apply very diluted fertilizer (one third of recommended dose) or succulent-specific fertilizer, one to two times in spring and early summer. Avoid excess nitrogen, which promotes foliage at the expense of flowering. No feeding in autumn-winter.
Pests and diseases
Watch for mealybugs and aphids, especially indoors. The main risk remains root rot from excess water. Ensure good air circulation and respect dry periods. If pests attack, isolate the plant and treat with an appropriate insecticide.
Did you know?
The Kalanchoe genus originates from Madagascar and the rest of Africa, where these fleshy plants have developed remarkable survival strategies in arid environments. Some species in the genus produce 'live plantlets' (bryophylls) along their leaves, which detach spontaneously to colonize the surrounding soil—a spectacular vegetative reproduction that Malagasy and other African peoples have used for generations for rapid propagation.
Where to buy it
Plant in spring, once all risk of frost has gone. Pick a plant with healthy foliage and roots that are not exposed. Best time: from April to June.
