Water regularly during the establishment period, especially during dry spells. Once established, Quercus trojana is drought-tolerant and requires minimal supplemental watering, primarily needing moisture during prolonged periods of extreme heat and dryness to prevent stress.

Pruning should be done primarily to remove dead, damaged, or crossing branches. It's best to prune during the dormant season (late winter or early spring) to minimize stress and sap loss.

Focus on shaping the tree and improving air circulation within the canopy.

Propagation is typically done through acorns, which should be collected from mature trees in autumn.

Sow them in a well-draining medium or stratify them in a moist medium in a cool environment for a few months before sowing. Germination can be slow and erratic.

Repotting is only necessary for young saplings that are container-grown. Mature trees are best left undisturbed.

For young trees, repot every 2-3 years in early spring, using a slightly larger container and well-draining potting mix, carefully preserving the root ball.
