How to Germinate an Acorn a Video Tutorial
1. Choose a batch of acorns that are healthy looking. Avoid acorns that are cracked, wrinkled, mouldy or with holes. For best results, we recommend sprouting several at once. Remember that we are dealing with nature and not all acorns germinate.
2. Soak the acorns in water for 48 hours. Discard any that float as they will not mature.
3. After soaking, wrap the acorns carefully in a damp paper towel and fold with the acorns tucked inside. Place the folded towel into a ziplock bag. At this point, you are encouraging the acorn to sprout, through a frequently practised method in horticulture called stratification. Stratification is tricking an organism into thinking it has just spent a cold wet winter outside in the ground.
4. If using a North American variety place the ziplock bag inside a refrigerator for germination. Be patient as the germination can take up time, anywhere from 2 days to 8 weeks. For British varieties keep ziplock bag out and keep it at room temperature. The correct level of temperature and humidity needs to be reached for the acorn to begin to grow.
5. Inspect the ziplock bag every few days to monitor the moisture level and the progress of the acorn. It is important that the towel remains wet. Once the taproot appears, it has germinated. Wait for the root to grow at least 1.5 cm before inserting on the open chamber of the Acorn Vase with root submerged in water.
