Can U Cut A Conifer Crossways And Not Kill It

Question

I would like to cut my conifers crossways to bring the height
down; they are 7ft tall and very thick. If I cut them crossways will it kill them?

Answer 1

The answer is yes, it could kill the tree. The thicker the trunk, the larger the open wound will be, which can allow diseases to infiltrate the tree. Here's an article that suggests some alternatives to this practice:
