Showerthought: everyone says leave the root flare buried til spring, but my maple in Dayton says otherwise
Last week I dug out a 12 inch deep volcano mulch ring a homeowner in Dayton had built around a 15 year old silver maple, against the usual talk that you shouldn't touch the root flare until spring planting season. I exposed the flare and cut two girdling roots that afternoon, and by Friday the bark at the base looked dry and solid instead of soft. Does anyone else think the wait til spring rule is mostly nonsense for established trees, or am I the only one digging in fall now?
