Billings County is a tough environment for lawns, with a difficulty score of 44.7. This is nearly 10 points lower than the state average, requiring specific strategies to maintain a green yard in zone 4b.
Struggling with Aridity and Heat
Low precipitation of 16.6 inches and 23 extreme heat days create a high-evaporation environment. Lawns require supplemental irrigation to survive these conditions, as the rainfall sits well below the 30-50 inches needed for natural lushness.
Neutral pH Meets Sandy Soil

Surviving 22 Weeks of Drought

Tough Turf for a Late Season
