Grafting Ginkgo cultivars. (1 Replies) Tweet paulhondorf Posted January 16, 2018 at 6:34 pm I have some Ginkgo seedlings and would like to try grafting some of the cultivars from my garden. When is the best time and proper technique? Thanks for any advice. Cancel Edit Save sampratt Posted January 25, 2018 at 2:16 pm Hello Paul. Ginkgo graft fairly readily, and now is the perfect time. It is important to graft them before the new leaves appear. Good luck! Cancel Edit Save You must be logged in to reply to this topic.
