Make Each Plant Individual and Important!
Minimize the number of big
plants in a landscape. Water is a scarce resource in the desert. Its price will
always increase. Lowering landscape temperatures and irrigation go hand in
hand. If water is used wisely, temperatures will decrease where water is
applied. Plants always require water when growing in the desert. Wherever
plants are planted in the landscape, water is needed. As they get bigger, they require more water applied further from the plant. Large mature sized plants
require more and more water as they grow bigger and bigger.
 |
| Every plant needs water. As plants get bigger, they need more water. Can you accomplish the same purpose by using fewer plants? |
Do Three Things
Do three things to your landscape
to become efficient in its water use; preserve only the plants that provide you
and your home the most cooling and pleasure, improve the irrigation system, and
learn how to water. The last one, “learn how to water”, should be first.
Learning how to water landscape plants enlightens the others.

| Shade from a small deciduous tree falling on the south windows and walls of the home can reduce energy costs for air conditioning by 20 to 25%. |
Shade South and West Sides
Shade the south and west sides,
walls and windows of your home and outside sitting areas. This type of
irrigation creates “oasis landscapes”, perfect for the desert. Plan to apply the
most water to “oasis” areas. Trees and shrubs provide the most cooling for
homes and sitting areas. There is nothing wrong with open areas, but they will
be hotter. Make these open areas interesting to look at.

| Sometimes being creative in your design can save water. Here a trellised plant provides shade on the opening of a door. |
Make Shade from Nonplants
Shade doesn’t have to come from
plants. Shade also comes from man-made structures. Concrete and steel
structures are the best choices for desert climates and don’t use water. There
is nothing wrong with artwork in landscapes. Consider man-made structures in
combination with vines or smaller plants instead of trees. Small plants use
less water than big plants. Where are large plants found in the desert?

Drip Irrigation May Not Be for YOU
Drip irrigation is among the
most efficient ways of irrigating plants. But if you don’t know how to use it,
it’s no better than flooding the landscape with water. Plants growing above 3
feet tall should be watered less frequently. Roots of tall plants will find
water applied to the smaller plants and adjust their root growth to where water
is applied in these areas.
 |
| Basin irrigation can be just as efficient as drip irrigation. Keep the floor of the basins flat and the sides in repair. |
Take Charge of Watering!
A well-designed irrigation
system and the knowledge how to use it puts you in charge of watering rather
than the landscape telling you when it needs water.

| Take charge of your irrigation and plant growth and you can have what you want and afford it. |
