If you can think of it what is the additive sometimes evergreens need in the ground to stay alive and perky/? I want to suggest this to my new neighbor to the North of me. she has I am told two big evergreen/ pine trees and for the first time in 13 years that tree has needles blowing some 75 feet over into my swimming pool. I always thought dead pine needles fell straight down. if you have any suggestions I would appreciate it. thanks thanks Lee -- Think honk if you're a telepath.
