Xeriscape Landscapers in St. George

2 companies in the St. George area advertise xeriscape, native-plant, or water-wise landscaping. Before you call one, here is what the local climate asks of a low-water yard, which rebates are open, and the questions that separate a real xeriscape contractor from a rock-and-weed-fabric crew.

Before you hire: 8 questions to ask a St. George xeriscape contractor

  1. Will you wait for rebate pre-approval before touching the lawn?

    Landscape Incentive Program (Utah Water Savers (Utah Division of Water Resources and partner water conservancy districts)) requires approval before any grass is removed. A contractor who starts early can cost you Up to $3 per sq ft (varies by district/city). Ask them to build the approval date into the schedule.

  2. Can I see a written plant list with hardiness zones?

    Every plant should be rated to at least zone 8 here. Ask for botanical names, mature size, and water use, and for plant coverage at maturity. Many rebates require 50% or more.

  3. How will you convert the sprinklers?

    Spray heads in a xeriscape waste water and feed weeds. Ask whether planted areas get drip on a separate zone with a filter and pressure regulator, how unused spray heads will be capped, and whether the controller will be reprogrammed or replaced with a smart controller.

  4. What happens to the sod, and how will you prep the soil?

    Ask whether they will cut and haul the sod, smother it, or use herbicide, and what they will add to the soil. Many xeric plants prefer lean soil, so heavy compost everywhere can backfire. Loosening compacted ground after sod removal matters more.

  5. What mulch, how deep, and is there plastic underneath?

    Rock and wood mulch both work, but depth matters: rebate rules in the West commonly call for about 3 inches. Several programs prohibit plastic sheeting, and it starves soil of air and water anyway.

  6. Will I get a first-year watering schedule?

    New xeriscapes are not no-water in year one. Ask for a written establishment schedule by season. Plant container perennials and shrubs after the median last frost (Mar 14), or in early fall at least six weeks before the median first frost (Nov 10) so roots can settle in before the ground freezes.

  7. Is there a plant warranty, and what voids it?

    Get the length (often one season or one year) and the conditions in writing, including whether it covers winter kill and what watering records you need to keep.

  8. Are you licensed and insured for this work?

    Ask for a license or registration number and look it up with the Utah Division of Professional Licensing (DOPL) before signing, and ask for a current certificate of insurance. Utah Division of Professional Licensing (DOPL) lookup.
