Buying Guide
Key questions to guide your purchase:
- What is my lawn size and how often can I fertilize? Granular options like 10-10-10 are typically better for large areas and slow-release schedules, while liquids enable quicker results for smaller patches or targeted feeding.
- Am I overseeding, seeding, or maintaining established turf? Some formulas are designed for new lawns (weed prevention, quick green-up) while others focus on maintenance and root growth.
- Should I use a balanced 10-10-10 or a higher 16-16-16? If you have diverse plantings beyond turf, a broader spectrum like 16-16-16 can simplify feeding but may require soil testing to avoid over-fertilization.
- Do I need micronutrients or additives (iron, seaweed extract, amino acids)? These can improve uptake and color but are not essential for every lawn.
- What application method fits my schedule? Liquid formulas suit calendar-based regimes with regular spraying; granular products are often easier to apply with a spreader for even coverage.
