Drip Line

The drip line on a tree is a ring on the ground directly below the outer circumference of the tree’s branches.  Water your trees along their drip lines instead of at the base of their trunks to prevent root rot.  For deciduous trees, extend a few feet beyond the drip line.

Iron-Loving Trees

The 4% Iron in Milorganite is especially good for trees, like oaks, that thrive with iron in their diet.
