An irrigation system
is the best way to ensure adequate moisture for plants, shrubs and
trees, while reducing evaporation and other water loss.
Drip irrigation involves using flexible tubing in and around plants.
Emitters or miniature sprayers are inserted into the tubing where
needed. Most hardware stores and garden centers carry a wide assortment
of drip irrigation systems.
However, keep in mind
that as trees and shrubs become older and bigger, the drip irrigation
emitters probably will not provide enough water for them. At that point,
you'll need to set up alternative ways to help your plants get all the
water they need, perhaps with a slow-running garden hose placed under
trees, or an open furrow ditch or other system for hedge rows.
