Columnar Oaks top branches are bending away from tne trunk. Are they growing too fast? Should we prune them?

Question

Have 3 trees. One is upright. Other two are collapsing at the top and getting tangled.

Answer 1

It would be hard to say without photos. The problem is likely on the opposite end of growing too fast, though. Usually fungal infections are the cause of trees collapsing, but it can have other factors, such as too much shade, or even down to a lack of silica in the soil.

Please provide some photos, and I will be more than happy to help diagnose your tree.
