Managing Heat in the Little City
Falls Church faces 40 extreme heat days per year, which is significantly more than the 23 days seen in surrounding Fairfax County. With 41.8 inches of annual rain, the city is slightly drier than the state average, meaning irrigation is more important here.

This high-quality soil structure means that with minor lime adjustments, lawns can thrive with minimal specialized prep work.
Navigating Extended Dry Periods
Over the past year, the city has experienced 32 weeks of drought, necessitating a focus on water conservation. Although the entire city is currently abnormally dry, there is no severe drought present (D2+). Implementing water-saving habits like morning-only irrigation will help maintain turf through these frequent dry stretches.
Selecting Resilient Grass for Falls Church
Given the 40 days of extreme heat, a heat-tolerant fescue blend or a warm-season grass like Zoysia is recommended. While specific frost dates are not provided for the city, following a late September seeding schedule is typically the best path for success in Zone 7b. Focus on varieties that can withstand the city's unique urban heat island effect.
