Where to Water: Out on the Edge

Where to Water? Scottsdale Xeriscape Garden

Apply Water around the canopy edge where "feeder" roots absorb water and nutrients. As the plant grows, move emitters or hoses outward to keep pace with the expanding canopy and root system.

Drip Emitters
Emitters "drip" water at a slow rate, such as 1,2 or 4 gallons per hour. A 1-gallon emitter running for 30 minutes applies only 2 quarts of water - not enough to soak a root zone! Run your system as long as needed for emitters to apply sufficient water or add emitters with higher flow rates.

Seasonal Watering
Many variables influence how often plants need water, including the season. Warm weather requires more frequent watering than cool weather. Jot a reminder in your calendar to adjust the irrigation timer at least 4 times per year.
