Water Phoebe sheareri thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot. Reduce watering frequency during winter months when the plant's growth slows.

Ensure good drainage in the pot to prevent excess moisture buildup.

Prune Phoebe sheareri to maintain its desired shape and size, and to remove any dead, damaged, or crossing branches.

Light pruning can be done anytime, but heavier pruning is best done in late winter or early spring before new growth begins. Use clean, sharp pruning tools.

Phoebe sheareri can be propagated from semi-hardwood cuttings taken in mid-summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix.

Keep the cuttings consistently moist and warm, and provide a humid environment. Rooting can take several weeks.

Repot young Phoebe sheareri plants every 1-2 years in spring, or when they become root-bound. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix.

Mature plants can be repotted less frequently, perhaps every 3-5 years.
