Santiria trimera prefers consistently moist soil, but avoid waterlogging. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly during cooler months, but never let the soil dry out completely.

Ensure good drainage to prevent root rot.

Prune Santiria trimera to maintain desired shape and size, or to remove any dead, damaged, or crossing branches. Pruning is best done in late spring or early summer after flowering.

Use clean, sharp pruning shears to make precise cuts.

Santiria trimera can be propagated from seeds or stem cuttings. Seeds require stratification and specific germination conditions.

Cuttings should be taken from healthy, mature stems in spring or early summer and treated with rooting hormone for best results.

Repot Santiria trimera every 2-3 years, or when it becomes root-bound. Choose a pot that is slightly larger than the current one and use a well-draining potting mix.

Repotting is best done in spring before the active growth period begins.
