Deep root fertilization, helpful or scam?
I had my tree service company look at a blue spruce that's pretty green, not as blue as the rest of them in the row. I'm aware it was a mistake to plant the blue spruce in such a wet location. We were thinking it was pest damage but here's what the guy wrote on the service paper.
"Spruce is browning due to cultural isses. Tree is located in a lower area where water tends to sit. This causes stress and could be causing root rot. I would recommend a deep root fertilization to promote as much root growth as possible to take advantage of the wet conditions."
So do you think deep root fertilization could be helpful or is it just a money making scam for these tree service companies?
