New Seeds: Ginkgo – Ginkgo biloba

Ginkgo Seeds

Last weekend, I wanted to order some pine seeds from Ebay, because my last attempt to get them to germinate failed epically. To make the shipping costs more worthwhile, I checked out this guy’s shop and found Ginkgo seeds. I didn’t have Ginkgo biloba on my wishlist, but this is such a cool tree and I think the oldest species around. So why not? I was curious what the seeds would look like, but didn’t really have a mental image or something. This living fossil was declared Tree of the Millenium in Germany, but I couldn’t find which millenium. Too bad.

I had ordered 10, but there were 11 in the bag, probably because one of the shells was already broken so much that the seed almost fell out.

Sowing Ginkgo Seeds

It said on the instruction that came with the seeds to put them in the fridge for 4 weeks at 4-5°C (39-41°F). I think I measured once that my fridge has 8°C. Anyway, I cracked the quite soft and thin shells a bit with the back-end of a knife and put half of them into a wet paper towel and into a plastic box with a lid and into the fridge. (I will read my fridge manual tomorrow, if I can find it.) The other half I put into warm water and will let it soak for 24 hours. That was also suggested in the instruction, but for after the 4 week period of stratification.

That was the day before yesterday. Today I put the six seeds having been soaked overnight into soil. Yesterday, I put them into the egg carton nursery pots I had come up with yesterday. The minute I had put them in, I remembered that I had just 5 minutes earlier thought it a stupid idea to put them into a bio-degradable pot because of their long germination period. Well, too late. I will be more considerate with the ones in stratification. The instruction doesn’t say anything about the germination period and temperature, but I read in another blog that the ideal temperature is 21-24°C (70-75°F). It suggested sand, so I will hopefully remember to use a mixture of sand and potting compost. (I forgot about that yesterday…)
