Buying Guide: Key Purchase Considerations
- Lawn size and coverage: Match product coverage to your yard’s square footage to minimize waste and ensure even feeding.
- Application method: Choose granular products for slow release or liquid formats for quick color response and easier spread via hose-end sprayers.
- Soil and existing conditions: If your soil is phosphorus-sensitive, a 29-0-3 option helps limit phosphorus input while providing nitrogen for growth.
- Environmental impact: Some formulations use iron to boost color without excessive application; consider slow-release options to reduce runoff and frequency of applications.
- Safety and pets: Check directions for pet safety and wait times after application before re-entering the treated area.
- Availability and storage: Bagged granular fertilizers are vehicle free for storage, while liquids require proper sealing and upright storage.
- Brand reliability: Reputable brands such as Jonathan Green, Scotts, and Lawnifi provide consistent results and clear instructions for best results.
- Lawn goals: Choose a product based on goals—quick greening vs. long-term color maintenance—and consider whether you need a supplemental iron boost.
