Where Should You Plant a Zempoaltepec oak?
Choose a spot with full sun and well-draining loamy soil with good organic content. Avoid low spots where water collects after rain.
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.

Zempoaltepec 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 Zempoaltepec oak?
Prune Zempoaltepec 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 Zempoaltepec oak in Winter?
Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.
Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.
