Water Guaiacum nellii thoroughly when the top 2-3 cm of soil feels dry. Allow excess water to drain completely to prevent root rot.

Reduce watering frequency during cooler months or when the plant is dormant, ensuring the soil does not remain waterlogged.

Prune Guaiacum nellii lightly to maintain shape, remove dead or damaged branches, and encourage bushier growth. Pruning is best done in late winter or early spring before new growth begins.

Use clean, sharp pruning shears to make precise cuts.

Propagation of Guaiacum nellii is typically done by semi-hardwood cuttings taken in summer. Dip cuttings in rooting hormone and plant in a well-draining propagation mix.

Maintain high humidity and warmth until roots form, which can take several weeks.

Repot Guaiacum nellii every 2-3 years or when it becomes root-bound. Use a well-draining potting mix, such as a cactus or succulent blend.

Choose a pot only slightly larger than the current one to avoid overwatering issues and encourage healthy root development.
