We have a mimosa tree in Portland Oregon. We love this tree and it seems healthy but is over 40 years old. Is this tree at a high risk for uprooting during sevee winds because of its age and type of tree? Can we cut it back 50 percent or will this damage/kill it?

Silk Tree or Mimosa (Albizia julibrissin) can be a tree that fails after a certain age. I have a friend who loves the trees so much she happily replaces it when one is lost. This doesn't mean your tree is going to fail, however. Reducing the size of trees once they are grown doesn't work because it weakens the tree, often leading to a slow and costly decline.
If you are specifically seeing signs of trouble, or the tree size itself worries you because of damage it can cause, you may need to remove the tree. Consult with a professional who can come to your site. Hire a certified arborist and find out what the consultation fees are when you shop for one.
