Irrigation Effectiveness
Overhead (Sprinkler) Irrigation vs. Soil Applied (Low Volume) Irrigation
The method in which irrigation is applied greatly affects plant growth and appearance. While most landscape plants show little to no aesthetic damage due to recycled water, a few plants are sensitive to recycled water when applied with overhead irrigation. Leaves of some sensitive plants tend to burn. This occurs when there is direct absorption of sodium and chloride into the leaves and is most likely to occur during hot, dry weather.

Smart Watering
Some of the benefits of good water management include:
  • More effective use of dollars spent on irrigation water
  • Improved landscape appearance with fewer wet or dry spots
  • Reduction of runoff to streets and over sidewalks
  • Reduction of water lost below the active root zone
  • Reduced fertilizer and other chemical requirements

Irrigation System Performance
Whether watering with overhead sprinklers or a low-volume system, keep in mind the following simple rules:
  • Water early in the morning when temperatures and winds are low and humidity is high.
  • Avoid watering during the heat of the day, when water will evaporate quickly, often leaving a white residue on the foliage.
  • During the summer, occasionally water 10 to 15% more than is usually required. The extra water carries the dissolved salts safely below the active root zone and prevents harmful salt accumulations.

Smart Watering Tips
Use best management practices (listed above). Evaluate the optimal irrigation method for your landscape. Leach landscapes occasionally to avoid salt accumulation.
