Pruning pyramidal arborvites

Asked June 9, 2020, 6:19 PM EDT

We have approx. 50 pyramidal arborvites bordering our backyard. They are 18 years old about 15 ft. High but we have had them trimming twice over the years. There is a lot of dead wood inside the trees some measuring an inch or more in diameter. There is no growth on these branches. Is it a good ideas to cut these branches off. We thinking that with these branches gone the live branches will receive more nutrients. Thank you.

Those look great. Here are some resources about caring for your arborvitae. It looks like they do NOT recommend cutting those branches in the dead zone. I’ve also included a resource about nutrients for your trees.
