Lawn and garden

Lawn care, planting dates and water-wise yards for Utah's growing zones.

Utah is one state with half a dozen gardening climates. St. George averages 205 frost-free days a year and Lake Town averages 87, and a good plan for one yard can be a bad one for the next valley over.^[1] This guide pulls the answers from the people who measure them: USU Extension, the USDA hardiness map, the Division of Water Resources, Slow the Flow and Localscapes.

60%of municipal and industrial water goes to outdoor landscaping^[2]

4 to 9USDA hardiness zones across Utah^[3]

35%most lawn a northern Utah Localscape allows in front and in back^[4]

$3per square foot, the top turf-removal rebate^[5]

Start with Zones and frost dates to learn your climate, then use the lawn calendar and vegetable planting dates for your town. The region guides below pull the numbers for your corner of the state and link every city page we have. If you are thinking about replacing grass, read Waterwise landscaping and Rebates before you rip anything out, because most rebate programs require you to apply first.^[5]
