Water
Allow the soil to dry out completely between waterings. Overwatering is a common cause of root rot. In winter, reduce watering significantly, providing only enough to prevent severe wilting.
Ensure good drainage to prevent waterlogging.
Safety note: This plant may be toxic to humans and pets. See toxicity details.

Prune Kalanchoe longiflora to maintain shape and encourage bushier growth. Remove spent flower stalks promptly. Pruning can be done after flowering or in spring to remove any dead or leggy stems. Use clean, sharp tools.
Easily propagated from stem cuttings or leaf cuttings. Allow cuttings to callus over for a few days before planting in well-draining soil. Roots typically form within a few weeks.
This is best done in spring or early summer.
Repot every 2-3 years or when the plant becomes root-bound. Use a gritty, well-draining potting mix suitable for succulents. Repotting is best done in spring before the active growing season begins.
Choose a pot only slightly larger than the current one.
