Gaultheria acuminata prefers consistently moist soil but not waterlogged conditions. Water deeply when the top centimeter of soil feels dry to the touch.

Reduce watering slightly during winter dormancy, but avoid letting the soil dry out completely. Ensure good drainage to prevent root rot.

Prune Gaultheria acuminata to maintain its shape and encourage bushier growth. Lightly trim in late spring or early summer after flowering to remove dead, damaged, or crossing branches.

Avoid heavy pruning, as it can stress the plant and reduce flowering for the next season.

Propagate Gaultheria acuminata from semi-hardwood cuttings taken in mid-summer. Dip the cuttings in rooting hormone and plant them in a well-draining, acidic potting mix.

Maintain high humidity and warmth until roots develop, which can take several weeks. Alternatively, propagate by layering in autumn.

Repot Gaultheria acuminata every 2-3 years, or when it becomes root-bound. Use a well-draining, acidic potting mix. Repot in early spring before new growth begins.

Choose a pot that is only slightly larger than the current one to avoid excess moisture retention and promote healthy root development.
