Trunk bends or leans
Trunks that bend are not necessarily weak and ready to fall. The tree in the right photo has a huge bend in it but the tree appears to be sound. On the other hand, a leaning trunk can be concerning, especially if the base of the trunk is leaning because roots are defective or were severed (see trees below).
The tree below-center snapped off at the point where the two main stems joined because it began to lean dramatically. Treatment: Small trees (less than about 4 inches trunk diameter) that are leaning can be staked in the upright position (See: details). Larger trees with bends or leans that are concerning can be reduced on the side of the lean or the tree can be removed from the site. Evaluation by a professional arborist is the best way to deal with this situation. Click here for more on bends and leans.
