Persistent dry conditions require care
The entire county is currently experiencing abnormally dry conditions after a full 53 weeks of drought over the last year. Implementing xeriscaping or reducing lawn square footage can significantly lower your water footprint in this vulnerable climate.
Timing your Box Elder lawn
