At the xeriscape show last week, I picked up a nifty new rain gauge, courtesy of the Albuquerque Bernalillo County Water Utility Authority, with this helpful advice:
Skip one watering when you receive at least a quarter of an inch of rain.
The last time that happened at my house? September.
The other irony is that little gauge goes up to four inches. When is the last time you saw any accumulation above an inch?
Around here, they collect dust and sand.
