How to germinate Ginkgo biloba seeds
This is the guide to share our experience on how to germinate Ginkgo biloba seeds. Ginkgo seeds are like plums, but the juicy part of the fruit has such unpleasant smell that the specimens found in cities are almost all males so they don’t produce any seeds. The seed itself is the nut inside the juicy fruit.
In previous years we tested the efficiency of stratification in Ginkgo seeds. We put a group in the fridge and sown other one right after seed collection (in Autumn). We found out that the same rate of germination happen in both groups, so the refrigerator cold was “so good” breaking the dormancy as the natural winter cold. Ginkgo seeds are very reliable and since you follow some simple steps we explain next you can expect that almost all seeds will germinate.
Here is how to do it:
1. Fill the pots and place the seeds
We usually use small pots to sow Ginkgo seeds. We use trays for smaller seeds, but for ginkgo and other big seeds we sow individually or some seeds for pot. We fill 3/4 of the pot with a generic potting soil. Something that retains humidity but drains well and dispose the seeds in it as shown in the pictures below
2. Cover the seeds
Slightly cover the seeds with a thin layer of soil, just to protect them and keep the humidity around the seeds.
