Pignut Hickory, Carya glabra, prefers consistent moisture, especially when young and establishing. Water deeply once a week during dry periods, ensuring the soil drains well. Mature trees are quite drought-tolerant.

Avoid waterlogged conditions, which can lead to root rot. Reduce watering frequency as the tree matures.

Prune Carya glabra primarily to remove dead, damaged, or crossing branches. The best time for pruning is during the dormant season (late winter) to minimize sap loss and stress.

Avoid heavy pruning, as it can affect the tree's natural form and health. Make clean cuts just outside the branch collar.

Propagation of Carya glabra is typically done through seed. Seeds require a period of cold stratification to germinate. Sow seeds in fall or stratify them artificially for 90-120 days at 1-5°C.

Grafting is also possible but more challenging, usually performed on rootstock of other Carya species in late winter.

Repotting is generally not applicable for mature Carya glabra trees as they are typically planted as container-grown specimens or directly into the landscape.

If a young tree is root-bound in a container, repot in spring into a slightly larger pot with well-draining soil. Minimize root disturbance.
