Guioa coriacea prefers consistently moist soil but dislikes waterlogging. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering slightly during cooler months, allowing the soil to dry out a bit more between waterings to prevent root rot, especially if grown in containers.

Prune Guioa coriacea to maintain its shape, remove dead or damaged branches, and encourage bushier growth. Light pruning can be done at any time of year.

For more significant shaping, prune in late winter or early spring before new growth begins. Use clean, sharp tools.

Propagation of Guioa coriacea is typically done through seeds or semi-hardwood cuttings. Seeds require warm temperatures and consistent moisture for germination.

Cuttings should be taken in spring or summer, treated with rooting hormone, and placed in a moist, well-draining medium in a warm environment.

Repot Guioa coriacea every 2-3 years, or when the plant becomes root-bound. Choose a pot that is one size larger than the current one. Use a well-draining potting mix.

Repotting is best done in spring, just as new growth begins, to minimize transplant shock and allow for quick recovery.
