Expert Response
The maple tree pictured is planted too deep. There should be a root flare visible. Planting trees too deep, especially maple trees can cause circling roots to kill the tree over time. And they can develop weak root structure and become dangerous because they can fall during high winds. Scraping the dirt away and raising the tree while it is adjusting is possible.
