Most Trees Are Planted Too Deep in the Ground
Trees too deep in the ground, an all too common problem, have two basic problems. When the trunk flare is under ground, it stays moist and doesn't breathe properly as bark is supposed to do. Soil too high on the trunk also often hides circling and girdling roots which choke the tree and drastically slow down growth. Many trees are snapping off at the ground surface because of this problem. Trees grown in containers are highly subject to this damaging condition. To make matters worse, mulch is often piled up on trunks.
Wrong: Improperly Exposed
Right: Properly Exposed
Solution? Get the mulch and soil off the trunk and off the flare. If you do the soil removal yourself, use hand tools and gloved hands being extremely careful not to damage the wet bark tissue. Water can be used but only with a soft flowing stream. Strong water blasts can severely damage the soft bark on the base of the trees. The best route is to hire an arborist that uses the Air Spade. It is a fancy sandblasting type tool that blows air (no sand) at a high velocity and removes the soil without damaging even the smallest roots. Arborists that don’t use this tool or the Air Knife should be passed on when hiring a tree care company.
