Hello everyone,
I am working with an existing plantation of American elm trees planted on a
10x10ft spacing. The elms are several years old. We have decided that we
would like to prevent them from root grafting. We're planning on trenching
between the elms and installing some kind of barrier in the soil (metal
sheets?) to prevent them from root grafting. If you have any experience
with this kind of work, I would really appreciate your input on equipment
and methods needed to do this successfully. Thank you for your help.
Sincerely,
Kathleen S. Knight
