| Pre-Planting Treatments: | Soak clean seeds overnight in fresh water. Remove any floaters. Drain and rinse in a 5% bleach solution for 1 minute. Rinse. Place acorns in a plastic freezer bag with an equal amount of perlite. Keep in refrigerator at 15C. Check after 1 month for germination. Remove and sow acorns with radicles 1/4 inch long. Check weekly until all acorns germinate. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Shadehouse. Sowing Method: Direct Seeding Germinants. Acorns are sown sideways and are planted 0.5 times the diameter to depth. Containers 2"x5" tubes (Deepot 40) used are filled with standard potting mix of peat moss, fir bark, perlite, and sand. Containers are watered with an automatic irrgation system. Keep media evenly moist. Do not allow to dry out. Place containers in cages to protect acorns from birds and rodents. Germination: 90% |
