Nothofagus X prefers consistently moist soil, especially during its establishment phase and dry periods. Water deeply when the top few centimeters of soil feel dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering frequency during winter dormancy.

Prune Nothofagus X primarily to remove dead, damaged, or crossing branches. This can be done in late winter or early spring before new growth begins. Avoid excessive pruning, as it can stress the tree.

Focus on maintaining a natural shape.

Propagation is typically achieved through grafting onto suitable rootstock, as hybridization can result in seeds that are not true to type or difficult to germinate. Cuttings can be challenging to root, but semi-hardwood cuttings taken in summer may be attempted.

Young Nothofagus X plants may benefit from repotting every 2-3 years to refresh the soil and check root health. Choose a pot only slightly larger than the current one.

Repotting is best done in late winter or early spring, just before the growing season begins.
