This vine has spread over 2 small cedar trees and seems to be impeding their growth. I have cut it back a lot. Should I dig it out?
Trust you are well
The picture enclosed makes it hard to identify the species of vine that is effecting your cedar trees.
To the extent that you did not plant this vine and do not wish to have it, it would be a good idea to get rid of it, especially if it is affecting their growth. Additionally, it may be an invasive species such as the winged euonymus, see for example:

Cutting it back may only delay its growth and as it regrows it will effect your desirable trees. If you are able to remove it entirely with its roots that would be most beneficial.
