Growing Instructions
- When and Where to Plant: Plant oaks in early spring or fall. Choose a site with full sun and well-drained soil.

- Watering: Water young trees regularly until established. Mature oaks need less frequent watering.
- Fertilizing: Apply a balanced fertilizer in early spring if necessary.
- Pruning: Prune in late winter to remove dead or diseased branches and to shape the tree.
- Seasonal Care: Mulch to conserve moisture and control weeds.
