March
- Mow

- Fertilize
- Weed control
Early-to-mid March is the main crabgrass pre-emergent window in the Charlotte Piedmont (NC State pins it to about March 15, when 2-inch soil nears 55F and forsythia is blooming). Get it down and watered in now. Tall fescue is greening and growing fast in the mild weather, so resume mowing at 3 to 4 inches once it's actively growing. Spot-treat early broadleaf weeds like dandelion and clover while they're small. A light spring fertilizer feeding on fescue is fine now, but keep it modest; the big fescue feeding belongs to fall, not spring.
