What Soil Mix Works Best for a Cuban Oak?
Well-draining loamy soil with good organic content. Good drainage is essential for Cuban Oak to prevent waterlogging, which leads to root rot and fungal issues.
Where Should You Plant a Cuban Oak?
Choose a spot with full sun and well-draining loamy soil with good organic content. Avoid low spots where water collects after rain.
Cuban Oak is suited to USDA Zone 10b – 11b.
Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.
How Far Apart Should You Plant a Cuban Oak?
Cuban Oak can spread to about 60 ft (18.3 m) and reach about 80 ft (24 m) tall. Space plants about 60 ft (18.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Cuban Oak?
Prune Cuban Oak while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.
How Do You Care for a Cuban Oak in Winter?
Cuban Oak is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Cuban Oak can be propagated through acorns, grafting. Similar propagation techniques also apply to english oak plant care, which shares the same genus.
