Vent: A big oak in my neighbor's yard taught me a hard lesson about soil compaction

Three years ago, I took a job to prune a mature white oak in a new housing development outside of Raleigh. The ground looked fine, just some fresh sod. I spent a whole day up there, doing what I thought was a good structural prune. Came back last week for a different job a few streets over and saw it. The tree is in serious decline, maybe 40% canopy loss. I talked to the homeowner, and it turns out the builder had parked a dump truck full of gravel right over the root zone for two months during construction. I had just looked at the tree, not the whole site history. Now I ask about soil work and equipment storage from the past five years before I even give a quote. What's the best way you all check for that kind of hidden damage on a residential call?

That "whole site history" check is smart. I read about using a simple soil probe to check for compaction layers before even looking up.

A soil probe is a solid first step. It tells you a lot about what's right under your feet before you dig deeper. Finding a hardpan layer early can save a ton of trouble later. Good call combining that with the history check.

Yeah, that hardpan layer is no joke. I hit one last year and it was a mess, lee582. A good probe saved me from planting a whole bed that would have just drowned.
