Buying Guide: Key Purchase Considerations
- Weed targets and spectrum: Select a product that explicitly lists crabgrass prevention alongside other common weeds you encounter, such as annual bluegrass (poa annua) and broadleaf weeds.
- Coverage and bag size: Choose bags that align with your lawn size. Larger properties may benefit from 15,000 sq ft or larger bags, while smaller yards can use 5,000–6,000 sq ft options.
- Active ingredient: Dithiopyr and Prodiamine are common active ingredients for pre-emergents. Confirm compatibility with your grass type and consider how the ingredient interacts with any existing fertilizer programs.
- Timing: Pre-emergents are most effective when applied before weeds germinate, typically in early spring and/or fall depending on climate. Follow label timing precisely for best results.
- Application method: Granular formulations require even spreading with a spreader and may demand watering or rainfall shortly after application as directed by the label.
- Lawn type compatibility: Ensure the product is suitable for your grass species (Bermudagrass, St. Augustinegrass, Zoysia, tall fescue, etc.). Some products are versatile across many turf types, others are more region-specific.
- Long-term maintenance: Consider products that provide season-long protection and pair them with a proactive lawn care plan that includes mowing height management, irrigation, and occasional overseeding where appropriate.
- Safety and regional rules: Review any regional restrictions or safety precautions, especially if you have pets or children using the lawn area after application.
