Water Filicium thouarsianum thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.

Reduce watering frequency during cooler months when the plant's growth naturally slows down. Ensure good drainage to prevent waterlogging.

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

Light pruning can be done at any time, but heavier pruning is best done in late winter or early spring before new growth begins. This encourages bushier growth.

Propagate Filicium thouarsianum from semi-hardwood cuttings taken in late summer or early fall. Dip the cut end in rooting hormone and plant in a well-draining potting mix.

Keep the cuttings moist and in a warm, humid environment until roots develop, which can take several weeks.

Repot Filicium thouarsianum 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, typically a blend of peat moss, perlite, and sand. Repot in spring for best results.
