Why the right lawn fertilizer matters
Good lawn fertilizer is what turns your yard from meh to man, that looks good. It delivers the nutrients grass craves for stronger roots, richer color, and the kind of resilience to handle whatever summer throws its way. Whether you want fast greening or steady season-long growth, the right fertilizer makes all the difference.
What good lawn fertilizer delivers
- No pesticides
- Fast greenup and growth
- Slow release for steady feeding
- Specialized ingredients for resilience (and greening)
- Well water-friendly formula
Your lawn fertilizer questions answered
Q: When should I fertilize my lawn for the best results?
A: Fertilize when grass is actively growing and temps sit between 50–85°F. For cool-season grasses, that's spring and fall. Warm-season lawns thrive with late spring through summer feedings. Early morning or evening applications work best (your grass will thank you).
Q: What does N-P-K mean, and which ratio is best for my lawn right now?
A: N-P-K stands for nitrogen, phosphorus, and potassium. Nitrogen fuels growth and greening, phosphorus supports roots, and potassium builds resilience. Most established lawns do well without phosphorus, but new lawns can benefit from added phosphorus.
Q: How often should I fertilize, and how much do I need per 1,000 square feet?
A: Apply liquid fertilizer every 4–6 weeks during the growing season. Granular fertilizer goes down less often since it releases slowly. For granular, use about 3 lbs per 1,000 sq ft. Liquid pouches cover 3,000–5,000 sq ft depending on the formula.
Q: Are kid- and pet-safe lawn fertilizers effective, and how soon can the yard be used after application?
A: Yes, pesticide-free fertilizers work wonders. Sunday's formulas skip the harsh stuff while still delivering real results. For liquid, just wait until it dries. For granular, water it in and let it dry before the kids and pups return.
Q: Can I fertilize and seed (or overseed) at the same time?
A: You can, but timing matters. For best results, seed first and wait until about 60% of grass has sprouted (roughly three weeks) before fertilizing. This lets new seedlings absorb nutrients effectively. Fertilizer alone won't fill bare spots since it contains no seed.
Q: Should I choose organic or synthetic lawn fertilizer?
A: Both can grow healthy grass. Sunday blends nature-inspired ingredients like seaweed, kelp, and molasses with effective synthetic nutrients. No pesticides, ever. The goal is feeding your lawn and soil together for long-term health rather than just surface-level green.
