Germination Information

Pre-treatment: Seeds are stratified naturally by planting them in the fall in a thin layer of sand on mulched field beds. Some acorns may require cold to overcome epicotyl dormancy. Cold moist storage immediately after collection may be beneficial.

Establishment: Seeds are wild collected during fall months and are kept separated according to site, elevation and source. Some seeds were collected in Mesa Verde National Park, Colorado and Grand Canyon National Park, Arizona. There is some variation in pre-treatment and establishment protocols.
