Data Story

About Lawn Care in De Baca County, New Mexico

Middle Ground in De Baca

De Baca County holds a lawn difficulty score of 31.7, placing it just above the New Mexico state average. Maintaining a lawn in Zone 7a here requires more effort than the national average of 50.0, primarily due to extreme summer temperatures. Consistent care is the key to success in this high-plains environment.

Intense Sun and Arid Air

With 81 days of temperatures over 90°F, heat stress is a major factor for local lawns. The county receives 14.1 inches of rain annually, which meets the state average but covers only about a third of a lawn's needs. The growing season is generous, running from April 18 to October 28.

Managing Sandy, Alkaline Soils

The soil in De Baca is predominantly sandy (58.9%) with a pH of 7.63, which is more alkaline than the 6.0-7.0 ideal. While sandy soil drains well, it struggles to hold onto nutrients and moisture. Regular additions of compost are necessary to lower pH over time and improve the soil's water-holding capacity.

Navigating Moderate Drought

The county has experienced 22 weeks of drought over the past year, but currently lacks any D2+ severe drought areas. However, with 100% of the county classified as abnormally dry, water conservation remains a priority. Use the 14.1 inches of annual rain as a supplement to a focused, morning-only watering routine.

Ready for a Zone 7a Start

Bermuda grass is a top performer in De Baca, thriving in the 4,508 growing degree days available each year. Aim to seed or sod in late April after the last frost risk has passed. The alkaline-tolerant nature of warm-season grasses makes them well-suited for the local 7.63 pH soil.
