Water
Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is a common cause of root rot.
In its natural habitat, it experiences dry periods, so mimic this by reducing watering significantly during cooler months.

Watering, pruning, propagation, and repotting details from plant data
Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is a common cause of root rot.
In its natural habitat, it experiences dry periods, so mimic this by reducing watering significantly during cooler months.
Pruning is generally not required for Crassula tillaea as it naturally maintains a compact, low-growing habit. If any stems become leggy or damaged, they can be trimmed back to the base to maintain a tidy appearance and encourage denser growth.
Propagate easily from stem cuttings or leaf cuttings. Allow cuttings to callus over for a few days before planting them in well-draining soil.
They root readily in warm conditions with bright, indirect light and minimal watering.
Repot infrequently, only when the plant has become root-bound, typically every 2-3 years. Use a gritty, well-draining succulent or cactus potting mix.
Repot in spring, just as new growth begins, to minimize transplant shock and allow for quick establishment.
