Buying Guide
Key considerations when choosing a weed-control and fertilization product for your lawn include lawn size, weed types, timing, and preferred application method. Consider these practical questions to guide your selection.
- What is the lawn size and shape? Choose products with appropriate coverage to minimize waste and ensure even results.
- Are you dealing with existing weeds or primarily aiming to prevent new growth? Post-emergence products kill current weeds, while pre-emergents prevent future ones.
- Do you prefer granular granules or liquid sprays? Granules require watering and can be slower to start; liquids offer quicker action and easier mixing when using hose-end applicators.
- Is a combined weed killer and fertilizer appealing or do you want to separate weed control from feeding? Singles or multi-action products can save time but may offer less customization.
- Are there any grass type restrictions in your yard? Some products list grass species they should not be used on; ensure compatibility with your lawn variety.
Practical tips for best results
- Apply when weeds are actively growing and weather is favorable, typically spring through early summer.
- Avoid applying during drought stress or extreme heat to prevent lawn damage and reduce efficacy.
- Watering after application as indicated on the product label helps activate granular formulations.
- Keep people and pets off treated areas until the product has dried as directed.
