Residential Water Use Lawns, Gardens & Landscapes

Lawn and Landscape Irrigation

Lawns and landscapes can be designed and maintained to be water conserving, prevent runoff of fertilizers and pesticides and good looking. To develop a landscape that is water efficient, build the landscape with good landscape soils, create water zones within your landscape, choose well-adapted water saving ornamentals and turfgrasses, and utilize the correct irrigation equipment for your landscape. Read on for more information to help you design and manage your landscape for water efficiency.

Drought and Fall Irrigation

Currently, most of the state is in at least a moderate drought, with many areas affected by severe, extreme, and even exceptional drought conditions. The Farmer’s almanac is calling for a cold, dry winter, again, so moving into that with drought conditions already could be devastating to our plants.

Gaps and Overlaps in Lawn Irrigation

Dry spot due to lack of overlap in irrigation

All lawn sprinkler systems, whether they are in-ground or above ground, have flaws.  Some of the biggest are gaps and overlaps.

Actually, a well designed irrigation system, or the use of above ground spray heads utilizes overlaps in the form of “head-to-head coverage”.  This involves water from one head spraying all the way to the adjacent head and vice versa.  Since twice as much water is applied near the head as is at the end of the water stream, an even amount is applied if the system has good head-to-head coverage.

Irrigation Audits Helpful

Irrigation audit
Lawns need about one inch of water per week. During the hottest part of summer, they may need one and a half inches. Do you know how much water your irrigation system applies? Lawns require uniform watering so one area is not under watered while another is overwatered. Do you know if your system waters uniformly? Lawns are best watered deeply but infrequently. Do you know what this means and if you’re watering program meets this recommendation?

Winter Watering

We don’t think about our outdoor plants much in the winter months. Once plants go dormant for the year many people believe that they need nothing until spring, but that isn’t the case, especially in years with low or no snow or rain throughout the winter months. And this year it has been very dry with little snow cover. The Beatrice area has only received a little over 1 inch of precipitation since October, compared to just over 3 inches in normal years.
