Buying Guide for Bermuda Grass Crabgrass Control
- Pre-emergent vs post-emergent: Use pre-emergents in early spring to prevent crabgrass germination. Use post-emergents to kill existing crabgrass and other weeds.
- Active ingredients: Look for products that target crabgrass while being safe for Bermuda under proper application. Avoid products not labeled for Bermuda or warm-season grasses.
- Application timing: Timing is crucial. Apply pre-emergents before soil warms to prevent germination; post-emergents should be applied when weeds are actively growing.
- Coverage and dilution: For concentrates, calculate mix rate per square foot. For ready-to-spray, ensure full coverage without run-off.
- Lawn health: Consider products that also feed or strengthen Bermuda grass to reduce stress and improve recovery after weed control.
- Safety and guidance: Always follow label directions, wear protective gear, and keep pets and children away during application as advised.
