Root
damage is one of the leading causes of tree death.
Soil
compaction is very harmful to the root system of a tree because
it reduces the amount of space in the soil that would normally
be filled with oxygen and water. Vertical mulching may be
recommended because it cuts through the soil providing a well
aerated area around the roots. This aerated area then allows
the penetration of water and oxygen into the soil thereby
strengthening the roots of the tree. A power drill or an air
spade is used to drill holes approximately 2 inches in diameter
and 12 inches deep in a grid pattern beneath the canopy of
the tree. The holes are then filled with a compost mixture.
Vertical mulching reduces stress and strengthens the root
system of the tree.
