Hi, I would like to know if it is possible to root ginkgo biloba leaf, I would be grateful if you could help me
No you can't. I've reproduced Ginkgo by air-layering, and I heard it can be done by cutting in late winter under a cold frame (haven't done it) , but not by "leaf cutting", sorry.
A few days ago, when watching Youtube videos fom my TV, I noticed a video in the suggested videos list, that had title like "Propagating Gingko Biloba from leaf", or something similar. I thought that this would be interesting to watch, but as I was currently looking for different topic, I watched some other wideos first, but could not find this video later.
