On the ground, the line that marks the outer edge to which a tree's (or other plant's) branches spread. The drip line usually signals a change in microclimate, where the area under the tree, which sees less precipitation, sunlight, and wind and may also be subject to competition from the tree's roots (see root zone), meets an area that isn't sheltered by the tree.
The circumference around a plant formed by water that drips off its outermost leaves or branches.
a line around a plant directly under its outermost blanch tips: Roots seldom grow beyond the drip line.
the circle that could be made on the ground around a tree below the tips of the outermost branches of the tree.
the perimeter of the area under a tree's branches.
The area under the outermost branches of a tree or shrub.
The outer edge of a tree or shrub, the point where water would drip to the ground from the outer leaves of a plant. Often used as a reference point for feeding plants.
An imaginary circular line on the soil around a tree that mirrors the circumference of the tree's canopy. The tree's roots usually extend well beyond this line.
The circle which would exist if you drew a line below the tips of the outer most branches of a tree or plant.
Perimeter of the area under a tree delineated by the crown.
