Contractor planted trees too deep. Dig out and replant?
Hello all, I had a local landscape contractor plant a few trees in my backyard about a month ago. One of the trees started developing significant browning on its leaves, which led me down the rabbit hole of educating myself about proper planting techniques, and discovering that the contractor planted the trees with their root flares buried 6" to 12" below grade, with mulch piled (over landscape fabric) right up against the trunk 🤦. I also uncovered that the tree with the browning leaves also had bark damage along the trunk up to the point where it was buried.
I've already removed enough soil to expose the root flares, and removed the landscape fabric and excess mulch, but I'm looking for advice as far as asking the contractor to come back out to replant the trees at a more appropriate depth. Is that a reasonable thing to do given that the trees have only been planted a month and it's still reasonably cool? Or I am likely to damage the trees further by doing that?
