Possible Replacement and/or care for Winter damaged Columnar Trees
Our Columnar trees are older. They were there when we purchased the house 20 years ago actual age is unknown. They were damaged with the heavy wet snows in April. Our thoughts are to plant 6 or so new trees 5' to 6' high of the same species of tree interspersed with the existing trees so that we have some new growth if we loose one or more. Would you identify the species of the trees. In addition what can we do to help save the existing damaged trees. Thank You,
Hennepin County Minnesota
The columnar trees in the photo are arborvitae. Given their age and condition, it's probably best to replace them. Many varieties are available. A number are listed here: https://hortnews.extension.iastate.edu/2004/6-25-2004/arborvitae.html

If your aren't sure how to proceed, consider asking a certified aborist or forester to assess the trees' condition onsite and recommend a course of action.
