Waterwise gardening is a mindset, not rocket science, but simply using some common-sense methods and techniques to conserve a dwindling resource.
And expect some dramatic side effects.
One is lower water (and perhaps energy) bills.
Fewer harmful salts and minerals go onto the surface of the soil.
Waterwise gardening encourages growth of beneficial microbes, and beneficial macro-organisms (such as earthworms) that feed on them.
Finally, it helps create a bountiful and beautiful garden, healthier plants, healthier soil and ultimately a healthier environment.
You’ll find hundreds of articles and blogs about waterwise gardening and desert gardening here and a Waterwise/Desert Gardening Glossary.

These monitors not only measure rainfall, but they regulate irrigation systems automatically: all for less than $15.
The new Vigoro automatic rain monitor works in conjunction with any electronic water timer, sprinkler, soaker hose or drip watering system. In addition to measuring rainfall, it can shut off the systems when enough rain comes down.
It requires no batteries. Gravity and water pressure are the keys to operating the monitor. Gardeners can add it to their irrigation system quickly and easily.
No batteries? No external power source? What runs it?
It’s so simple, that gardeners will wonder why someone hasn’t thought of it before.
When enough rainfall occurs, a float inside the monitor lifts up and closes the water path between the water source and the system, shutting off the flow. It doesn’t need complicated adjustments or settings. In fact, it doesn’t need them.
It’s small
The rain monitor is 4.5 inches wide, 6 inches long and 2.5 inches high.
There are no replaceable parts.
Made completely of plastic, the little rain monitor and regulator will last about two years and has no moving parts except for the inside float, and the couplings at either end.
Cost? One major chain is offering the Vigoro Rain Monitor for $14.97, which is really inexpensive.
