3IG – Three Interrelated Groups
3IG – Three Interrelated Groups – are the keys to successful Landscape Water Management
This Interrelated Group has components that are often overlooked for cause and effect for Landscape Water Management. Some aspects of Landscape Features are hard to change, if not impossible:
- Site grading when your home was built; the home-lots in the neighborhood are sloped toward the street.
- Your neighborhood is located in an area with uneven terrain; hillsides and valleys.
- Your landscaping has added mounding and swales.
Other aspects of Landscape Features can be changed with varying difficulty:
- Location, size and shape of turf-grass areas; related to maintenance costs and irrigation performance.
- Plant type; Arizona Friendly (desert adapted) low water use trees and shrubs , Turf-grass, medium to high water use trees and shrubs.
- The right plant in the right place; size of the plant and competition between plants and turf-grass. Related to shearing and pruning and water use.
Describes how your plants are cared for:
- Do no harm.
- Pruning or Shearing; allowing your plants to be naturally shaped (no regular shearing) promotes healthy plants that require less water. Strive to balance the need for a manicured look with a more natural appearance.
- Turf-grass; mowing height and frequency as well as dethatching and aerifying affect health and water requirements for lawns.
- Properly controlling water delivery can positively affect (slow) growth rates. Reducing maintenance costs and lowering green waste delivered to landfills.
“Performance”, the term often used to describe the combination of uniformity and efficiency.
- Sprinkler selection and placement or spacing; related to size and shape of the watered area; irregularly shaped (odd angles, not multiples of 90 degrees), curvy, narrow turf-grass areas are hard to maintain and water.
- Drip systems expanded as the landscape matures; related to properly watering trees and shrubs to encourage deep rooting, well anchored plants that require less water.
- Management; controller scheduling and monitoring.
