Data Story
About Lawn Care in Duchesne County, Utah
Moderate difficulty in the Uinta Basin
Duchesne County's score of 31.4 makes it one of the easier Utah counties for lawn care, despite being below the national median. It stays within Hardiness Zone 6a, requiring turf that can handle cold winters and dry summers.
Extreme aridity with low heat
Receiving only 8.7 inches of annual precipitation, this is one of the driest counties in the state. Fortunately, only 22 days of extreme heat occur annually, which helps grass survive on very limited water supplies.
Alkaline and sandy soil challenges
The soil here is notably alkaline with a pH of 7.52, which is higher than the 6.0-7.0 ideal for lawns. With a high 41.7% sand content, the soil drains quickly, meaning you must water more frequently but in shorter bursts.
Persistent severe drought impacts
Over 41% of the county is currently in severe drought, and the entire area has faced 53 weeks of drought over the last year. Mulching clippings back into the lawn is vital here to keep the soil cool and retain as much moisture as possible.
Maximizing a dry season
Focus on drought-hardy grasses like Buffalograss or specific Fescue blends. The safest planting window begins after the May 19th frost, but you must keep new seeds constantly damp in this dry, 8.7-inch rainfall climate.
