This Drip Line coincides with
the area where the plant is growing tiny terminal Feeder Rootlets which
absorb moisture and nutrients from the soil. When the tree canopy gets
wet, any excess is shed to the ground to the thirsty Rootlets. They absorb
this moisture for the health of the plant.
When you apply fertilizing nutrients
to a plant, it is essential that you put them within reach of the Feeder
Rootlets, or your offering will be leeched away and mostly lost. The Drip
Line is a plants dinner table; put the nutrients on the table.
Know your plants and trees; some
have shallow roots near the surface, others have deeper roots that require
more water to be able to soak down to the depth of their Feeder roots.
If your irrigation is inadequate,
you will encourage the roots of young plants to grow up near the surface,
which will make them more dependent on frequent watering to satisfy them
and give them poorer holding power in the soil, which may result in uprooted
trees and shrubs in a storm.
