Garden & Ecology Notes
- Wildlife Value:
- birds, squirrels, deer, wild turkey
- Fall Color:
- red, orange, bronze

Propagation & Germination
- Stratification:

Pre-treatment: Seeds are mechanically seeded in mid-November. Field density ranges from 81 to 97 acorns/m2. Seeds may be floated in water to determine viability. Discard seeds that float and retain those that sink for planting.
Establishment: Seeds are collected from local people or from established natural stands. There is a variation in the length of the establishment phase between the two protocols.
