Water regularly when the top 2-3 cm of soil feels dry. Avoid overwatering, as Guaiacum sanctum prefers slightly dry conditions.

Reduce watering significantly during cooler months, allowing the soil to dry out more between waterings to prevent root rot.

Pruning is typically minimal and primarily for shaping or removing dead or damaged branches. Prune lightly in late winter or early spring before new growth begins.

Avoid heavy pruning, as it can stress the plant and impact its slow-growing nature.

Propagation is challenging and usually done by seed or cuttings. Seeds require scarification and may have low germination rates.

Cuttings from mature wood can be rooted under mist with rooting hormones, but success can be inconsistent. Patience is key.

Repot Guaiacum sanctum infrequently, only when it becomes severely root-bound, which is rarely needed for mature plants. Use a well-draining potting mix. Handle the roots gently during repotting, as they are sensitive.

This is best done in spring.
