My good friend Michael Feduccia of Plant City, FL has a new online shop up and running. If you're interested in top-quality bonsai, this is a site to bookmark.
Great trees presented well for online purchase. There are some exhibition-quality trees in great pots for sale right now. I'd be happy to help you in caring for, and futher developing, any of these great trees from Michael.
So head on over to his store. There are links to his Twitter feed and full website at the bottom of the page. Michael is one of the great young bonsai talents emerging in the US; keep an eye on him and his trees!
