Water: Gray oak flourishes in balanced sunlight and moisture, demonstrating moderate drought tolerance. Weekly watering is essential for its health, while indoor cultivation requires sufficient humidity, especially during the active growing season when water uptake is heightened.

Fertilize: Gray oak thrives without added fertilization but can benefit from a 12-6-6 (N-P-K) fertilizer for extra nutrients. Additionally, spreading mulch around them mimics their natural habitat, providing valuable organic matter and enhancing their growth.

Pruning: Gray oak has strong branches and thick foliage. Prune in early spring to remove dead or crossing branches, improving air circulation and light access. Regular thinning supports tree health, aesthetics, and longevity while reducing pest risks, ensuring vigorous growth.

Propagation: Gray oak is a resilient tree that can be propagated through semi-hardwood cuttings from healthy branches. Use rooting hormone and plant in well-draining soil. Regular watering and partial sunlight promote root development, allowing cuttings to mature into robust saplings for transplanting.
