  1. 1. Waterwise Plants for Lincoln & SE NebraskaPresented byThe Mayors WaterConservation Task Force
  2. 2. Waterwise Plants for Lincoln, Nebraska As Lincoln’s population continues to grow, newpressures will be put on available public water resources. Usingwater wisely in the landscape is a vital part of waterconservation. When you plan your landscape, be sure to includespecific goals to reduce water use. Although the plants listed here are valued for their lowwater needs, they still require regular watering during the firstyear. Plants develop healthy root systems when they arewatered slowly. This allows moisture to soak into the groundinstead of running off. When planting perennials, prepare the soil beforeplanting by adding organic matter. To enrich the soil, improveaeration and drainage, spread a 2-4 inch layer of organicmatter on the soil surface. Dig this layer in to a depth of 6inches. While compost or well-rotted manure is best, choppedleaves or grass clippings can be used although they may tie upsome of the available nitrogen in the soil, making an additionalapplication of fertilizer necessary. In most instances, soilimprovement is not recommended when planting trees andshrubs. Testing your soil before planting is always a good idea. After planting, add a layer of mulch over the soil toretain moisture and reduce runoff. Mulching also helps tocontrol weeds. Three to four inches of mulch is plenty. Lincoln nursery and garden centers will carry most ofthe plants listed in this brochure. If you have questions about aplant’s suitability in your landscape, contact your nursery orthe Lancaster County Cooperative Extension Service.
