Lawn & Landscape Irrigation

The good news about lawn and landscape irrigation is that you can have your cake and eat it, too! Lawns and landscapes can be designed and maintained to be good looking and water conserving.

Soils and zones

Start by building lawn and landscape soils with sufficient water retention for plant growth, yet allow excess water to properly drain away. Once good soils are in place, create water zones. Water zones are distinct sections of your property which contain plants with similar water needs. The first unique zone is the turf which should be separate from the other plants in the landscape; further subdivisions lead to greater water efficiency.

Right plant, right place

Choose well-adapted water-saving ornamentals and turfgrasses. This is a key component of the "right plant, right place" concept of selecting plants for the growing conditions of the landscape. Other selection criteria include plant height, fall color, disease resistance, bloom color and timing, winter appeal and level of maintenance.

Right equipment

It's crucial to match the irrigation equipment with the size, shape and type of landscape being watered. Knowing when to water for best plant absorption and health is another key water-saving method.

Measurement

Water application measurement both on lawns and ornamental plantings is one of the best steps towards a water-efficient landscape. Measuring the output of your sprinklers is easy to do, and if you make adjustments based on the results, you'll save money on your water bill.

Did You Know?

When deicers and salt run off paved surfaces, they often end up in soil, ponds, rivers or lakes. In high concentrations, salt is harmful to plants and wildlife. Shovel snow before it is walked or driven on to minimize ice formation and reduce the need for deicers. When needed, use minimal amounts of these chemicals or use gravel, sand or kitty litter as an alternative. When ice melts, do not sweep these into the street where they will be carried to surface water via storm drains.
