I removed three small deciduous trees from the orchard I took over that had their roots chewed up by gophers, were topped, and had root flare because they were planted too deep. One tree had crown gall to boot. There were also these fiberglass stakes in the ground that were buried 3-4 ft deep that I took out that bend like the reed and give off fiberglass splinters. Many of the trees are diseased with bacterial spot
I'm VERY new to arboriculture (only two months into it), but in the relatively short time that I spent in diligent study I can tell you that I think I have found tree hell, but fortunately I have a place to apply what I learned from literature and lurking this site.
Hopefully, I'll have the orchard producing again.
