Water Portulaca quadrifida thoroughly when the top 2-3 cm of soil feels dry. Allow the soil to dry out slightly between waterings. Overwatering can lead to root rot, especially in cooler temperatures.

Reduce watering frequency during winter dormancy.

Prune Portulaca quadrifida to maintain a tidy shape and encourage bushier growth. Lightly trim leggy stems to promote branching. Deadhead spent flowers regularly to encourage continuous blooming.

Heavy pruning is generally not required but can be done in early spring.

Portulaca quadrifida is easily propagated from stem cuttings taken in spring or summer. Insert cuttings into moist, well-draining potting mix. They root readily in warm conditions.

It also readily self-seeds, with new plants appearing from dropped seeds.

Repot Portulaca quadrifida when it becomes root-bound, typically every 1-2 years, in spring. Use a well-draining potting mix, such as a cactus or succulent blend.

Choose a pot that is only slightly larger than the current one to avoid excessive moisture retention.
