I have six young, 18-20 foot aspens in my front yard in Salt Lake City - I know that aspens are secondary forest trees and that they are not super happy in residential, valley neighborhoods, but I'm particularly nervous about mine. We've had an incredibly windy spring full of storms, and as a result, several of the six aspens are now leaning instead of standing straight. Is this a problem? Will they right themselves or remain permanently leaning? Do I need to help them or is leaning a normal part of their existence?
Can you post some pictures? It's hard to tell how bad the problem is without seeing pictures. First take one that shows the general angle at which they're leaning, and then one focusing on the base of the tree to see if it looks like the rootball is starting to lift out of the ground at all. If they're fairly recently planted and the rootball wasn't firmly anchored in the ground yet then you'll either need to straighten them up and stake them, or remove them if that's not possible, otherwise if you get another windstorm in it could continue to tip them over and then they could fall on something.
