What to know about hiring a Washington pro

The transition zone is the hardest US lawn climate — too hot for pure cool-season grasses, too cold for full warm-season recovery. Brown patch fungus is common in tall fescue lawns through humid July and August. Grub pressure peaks in late summer. Several states including Virginia and Maryland restrict phosphorus fertilizer. Tall fescue is the most reliable choice because it tolerates both summer heat and winter cold without going fully dormant.

When evaluating Johnson's Landscaping Service or any other lawn care provider in Washington, ask how they handle the local timing windows above — a pro who can explain their pre-emergent schedule and seasonal approach is one who knows the DC climate.
