Buying Guide
- Weed type and season: Select a product that matches your target weeds (broadleaf vs. grassy) and apply timing (spring for active broadleaf growth; fall for pre-emergent prevention).
- Pre-emergent vs. post-emergent: Pre-emergents block weed germination, while post-emergents kill actively growing weeds. Some products combine both benefits; choose based on weed pressure and lawn health.
- Lawn size and coverage: Check square footage coverage to ensure you don’t over- or under-apply. Some bags cover up to 5,000 sq. ft., others are more limited.
- Safety and environmental impact: Consider products with no glyphosate if you prefer an alternative. Read label directions for safe use around children, pets, and gardens.
- Grass health and fertilizer components: Some granules include fertilizer to promote turf growth; this can influence feeding schedules and mowing plans.
- Application method and weather: Dry or slightly damp conditions can affect effectiveness. Avoid applying before heavy rain unless the label allows it.
- Longevity and season-long protection: If ongoing prevention is needed, choose products advertised for season-long control, and follow reapplication intervals per label.
- Safety notes: Some products are more suitable for residential lawns than ornamental landscapes. Always read label warnings and keep away from non-target plants.
