Gevuina avellana prefers consistent moisture but dislikes waterlogged soil. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly during winter dormancy.

Ensure good drainage to prevent root rot, especially in containers. Avoid allowing the soil to dry out completely during the growing season.

Prune Gevuina avellana primarily to shape the tree, remove dead or diseased branches, and improve air circulation. Light pruning can be done in late winter or early spring before new growth begins.

Avoid heavy pruning, as it can stress the plant and reduce fruit production.

Gevuina avellana can be propagated by seeds, which require stratification (cold, moist treatment) for several months before sowing. Softwood cuttings can be taken in early summer and treated with rooting hormone.

Grafting is also an option for specific cultivars or faster establishment.

Repot young Gevuina avellana plants every 2-3 years in spring before active growth starts. Choose a pot that is one size larger than the current one, with adequate drainage holes. Use a well-draining potting mix.

Mature plants may not require frequent repotting and can be top-dressed instead.
