drip irrigation was designed with commercial agriculture in mind, millions
have already discovered the advantages of this type of irrigation system
which applies water equally well to landscaping trees, shrubs, and container
plants. Accurate amounts of water can be applied to the root zone of
each plant. Water is kept off windows, sidewalks, and driveways, and
plants receive the water that they need to flourish. A common problem
in landscape design has been that plants with different water requirements
could not be planted together. Drip irrigation overcomes this problem
by allowing different amounts of water to be delivered to different
plants in the same area.
If the entire area being irrigated is to be set up in one system (i.e.
water will be supplied by one valve), multiple or higher output emitters
can be placed by the plants which require more water. A preferable solution
is to set-up multiple systems, with plants that have similar watering
needs being placed on the same system. This allows large plants, such
as trees, to get the deep watering they require, while allowing the
frequent shallow watering that small ornamentals prefer.
can be buried or mulched to hide them from view. Emitters, however,
should not be buried, but can be brought to the surface by either bringing
the main polyethylene hose to the surface wherever the emitters are
attached to the hose, or by attaching a small adaptor and tubing to
the main line, and inserting the emitter, leaving only the emitter above
Small “Mini-Sprays,” are also useful in mixed landscape
areas. A common design is to water the ground cover between shrubs with
“Mini-Sprays,” while adding extra water near the base of
each shrub with drip emitters. Another good use of “Mini-Sprays”
is to water small plants or ground cover growing among rocks or bricks.
The flexibility of drip irrigation allows the removal of an individual
emitter or a spray from a system and replacing it with a “goof”
plug or to add new emitters or entire lines to a system with little
worry about design. If a line is accidentally cut, it can be easily
repaired with a coupling.
