Are there any problems with using photinias as a foundation planting? I am aware of the leaf spot problem but can they be pruned to a round shape and be kept at 3-4 feet? Thank you in advance. Chris in Maryland.
Would be hard to keep them that short for a long period of time, I would think. Sure, the first few years would be fine, but those things get 40+ feet tall. Imagine the trunk system that would evolve after time, you'd have a huge base on a very small tree. I could be wrong, but I think, after maybe a decade or less you'd have a funky tree.
Thought about Indian Hawthorns? Very low maintenance, hardy, easy to keep small and shaped.
