95% LOSS of Concolor Fir Trees. I Think I Know Why.

A lot of trees have died since we started our Christmas tree farm a few years ago. Many of those trees were canaan and concolor fir trees that seem to dislike our climate or the soil. We planted about 200 concolor fir two seasons ago and have lost almost all of them. There were some trees planted off to the side that I left for dead. Upon further inspection, under all the weeds, there were some surviving concolor fir trees that we'll go ahead and replant in the main field.
