Allow the soil to dry out completely between waterings. Euphorbia cotinifolia is drought-tolerant and prefers to be under-watered rather than over-watered. Inconsistent watering can lead to root rot.

Reduce watering significantly during the cooler, dormant winter months.

Prune to maintain desired shape and size, or to remove dead or damaged branches. Pruning is best done in late winter or early spring before new growth begins. Wear gloves as the sap can be irritating.

Cut back leggy stems to encourage bushier growth.

Propagate from stem cuttings taken in spring or summer. Allow cuttings to callus for a few days before planting in well-draining soil. Water sparingly until roots develop.

This is a relatively easy method to increase your plant collection.

Repot young plants annually, and mature plants every 2-3 years, or when root-bound. Use a well-draining potting mix, such as a cactus or succulent blend. Choose a pot slightly larger than the previous one.

Repot in spring before active growth begins.
