I started some tangerine seeds in February of 2010. They are the same age although one is significantly taller--5.5' tall excluding the container. I don't know how much longer I will be able to bring it indoors to protect it from zone 7 winters. If I prune down the height, I reduce thenode count and the tree will never fruit. I want to know if they are likely to fruit in the next year or two. I'm thinking of air layering a top branch on the tall plant so that I can begin a new tree yet conserve the greatest node count possible.

the plants looked like this a year ago.
