Follow Best Practices
Don't over-water. Get a custom irrigation schedule for your yard at www.TriValleyWaterWise.com.
Keep mulch at least two inches deep in all non-turf planting areas to reduce evaporation, keep soils moist, add nutrients, and discourage weeds.
Water between 6 p.m. and 9 a.m. to minimize evaporation--no longer a requirement but always a good idea.
Mow less frequently, set mower blade higher (3-3.5 inches), and mow during the cool parts of the day.
Aerate lawns and fill the plugs with compost so water can soak in deeply.
Fertilize and prune at the right time. New growth needs more water. To avoid stimulating new growth during hot months, do not user high-nitrogen fertilizers or prune after April.

Irrigate EfficientlyDry spots on your lawn mean the area is not getting water. Adjust or modify the irrigation system for better coverage instead of increasing watering duration. If unable to adjust, we recommend hand watering.
Ponding indicates over-watering or that foliage is blocking spray. Try decreasing the watering duration on your sprinkler system and trim any foliage blocking the sprinkler head.
Soil compaction can be seen in areas of high foot traffic and with clay soils. Aerate your lawn to increase air and water transfer to roots.
Thatch is the build-up of dead stems beneath the green surface of your lawn. De-thatching removes that build-up and lets water and fertilizers reach the soil efficiently.
Hydro-zoning is key to an efficient irrigation system. Set up your system so that each sprinkler valve serves plants that need the same amount of water. For example, shrubs and lawn should not be on the same valve because shrubs require less water than lawn.
Sun vs. shade - Consider sun exposure when setting irrigation run times. Decrease run times in shady areas.
Sprinkler heads - If you have brown spots or ponding, check your sprinkler heads for the following issues. All sprinkler heads connected to a single station (valve) should have the same application rate and cover the same distance to ensure proper distribution over your landscape. Heads should be straight up and down, not tilted. An efficient system should have even head-to-head spacing, meaning that the water from one sprinkler head should reach the sprinkler heads around it for uniform coverage.
Soil type is an important factor in efficient irrigation. Much of the soil in the Tri-Valley contains clay, which has a slow infiltration rate. Apply water slowly and in intervals to minimize runoff.
Check controller settings after a power outage - Some controllers revert to a default setting, such as "water every day for 10 minutes," after a power outage. Regularly replace batteries that provide backup power.
Tune Up Drip Systems
Location is important. Place emitters at the edge of the root-ball on new plantings and at the edge of the foliage of established plants.
High pressure - If compression fittings and emitters are popping off, pressure may be too high. Install a pressure regulator on the valve for all drip stations.
Broken tubing needs to be fixed immediately to save water and to efficiently water your landscape.
