put an order in with UCDavis. I got one cutting from them last year. I shared and with my half I grafted onto my tree root. I checked today and it has the cutiest green tip. Knock on wood, it survived our nasty winter, frozen ground (since it had my huge root) I also made a insulation with leaves outside of a 5 gallon water bottle with no bottom that was over the tiny tree. over the leaves,I wraped a plastic bag and pinned all in place. Since we may still get more cold weather, I am not removing the weathering aparatus yet. But it is good to see the tip is alive... not sure it will survive our weather, but again, it may. It is in the ground. I am scared of puting in a pot, since it is a graft.
