i'm having difficult time with planted pines, white, blue spruce etc. My pines were planted 1 and 2 years ago on the boarder of a swale between property lines.

I've lost 1/2 of my 13 trees planted. Natually, I assume to rootball is remaining wet and the trees can't breathe.

I'm not sure. can anyone offer advice? I really want a privacy screen, the guy next door has the same number of trees planted and he's lost none.

is it safe to replant in the same location? Thinking of switching to water loving tree.

suggestions?
