|Would golden chain trees be good candidates for container planting (ie; beside a patio so that it can espalier along the patio roof), and if so, how would we decide what size container to purchase?|
|Golden Chain trees can get quite large at maturity and may become difficult to prune into an espalier shape as they grow into maturity. I think a better approach is to choose a tree that remains small at maturity. Small trees have smaller root systems and are much more adaptable to container growing. You might consider a redbud, crape myrtle, ornamental fruit tree or loquat for container planting. If the site provides some afternoon shade, one of the smaller maples would work.
The container size will depend upon the ultimate size of your new tree. Something about 30 gallon (half-whiskey barrel) size should provide adequate root space for a small tree. Best wishes with your new tree!
