Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water Snow on the Mountain moderately during the growing season, allowing the soil to dry slightly between waterings.
Reduce watering significantly in fall and winter, providing just enough to prevent the soil from becoming bone dry. Overwatering can lead to root rot.
Prune Snow on the Mountain to maintain shape and encourage bushier growth. Deadhead spent flower stalks to prevent self-seeding, if desired.
Light pruning can be done any time, but major pruning is best after flowering or in early spring before new growth begins.
Propagate Snow on the Mountain by seed sown in spring, or by stem cuttings taken in late spring or early summer. Seeds require light for germination.
Cuttings should be allowed to callus for a day or two before planting in a well-draining potting mix.
Repot Snow on the Mountain every 2-3 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one.
Use a well-draining potting mix, such as a cactus or succulent blend, to prevent waterlogging.
