BUYING GUIDE
Key purchase considerations
- Form and application: Choose granular vs. liquid based on your spreader or sprayer availability and lawn size.
- Concentration: Higher nitrogen percentages deliver faster greening but require careful timing to avoid overfeeding.
- Release type: Quick-release nitrogen offers rapid color, while slow-release helps maintain color over weeks.
- Grass and plant type: Align nitrogen level with lawn species, vegetables, and ornamentals to prevent excessive growth or leaf burn.
- Organic vs. synthetic: Organic options (like blood meal) suit organic gardens but may act more slowly; synthetic options provide faster results.
- Soil health: Consider products with minimal salts and additives to protect soil microbiology and existing flora.
- Safety and timing: Follow label directions for timing around heat, rainfall, and mowing schedules to optimize uptake and minimize runoff.
