Swindon Bonsai has a nice article titled “Defoliation of Ginkgo’s” which goes into great detail about defoliation complete with nice photos of the process. Please note when using Chrome the thumbnail photos do not seem load. Please use either Firefox or Internet Explorer to view article. I have added the article to the Ginkgo Bonsai page under Deciduous Bonsai and Bonsai Tree Information pages.
