Granular Lawn Fertilizer

Feed your lawn the professional way. Lawn Synergy granular fertilizers deliver long-lasting nutrients, even coverage, and deep green results that liquid fertilizers can’t match.

Lawn Synergy’s granular fertilizers are professional-grade blends designed for long-lasting feeding, deep green color, and strong root development. Each product is engineered with multiple nitrogen sources, XCU® slow-release technology, potassium sulfate (SOP), ammonium sulfate, micronutrients, and balanced NPK ratios to feed lawns and plants evenly over time. Whether you’re fertilizing grass, palms, ornamentals, or correcting a deficiency, we have the perfect formula for every application.

What the Numbers Mean on Fertilizer Bags

The three numbers on every fertilizer label represent Nitrogen (N), Phosphorus (P), and Potassium (K) — the primary macronutrients your turf and plants need:

  • Nitrogen (N) – Drives top growth and deep green color.
  • Phosphorus (P) – Promotes strong root and seedling development.
  • Potassium (K) – Builds plant strength and resistance to drought, stress, and disease.

What Makes a Great Granular Fertilizer

  • Multiple nitrogen sources – A mix of quick and slow-release forms for instant and extended feeding.
  • XCU® slow-release nitrogen – Feeds for up to 10 weeks with reduced risk of burn or surge growth.
  • Micronutrients – Iron, sulfur, and other trace elements for deeper color and improved nutrient uptake.
  • Balanced NPK ratios – Tailored to specific lawn or plant needs throughout the year.
  • Professional-grade particle sizing – Ensures even distribution and consistent performance.

Why Granular Fertilizer Outperforms Liquid

While liquid fertilizers provide quick color, they’re limited by how much nutrient weight can be dissolved into solution. Granular fertilizers deliver complete nutrition that liquids simply can’t hold. A granular blend contains multiple nitrogen sources, potassium, sulfur, and micronutrients in solid form — providing a higher nutrient load, steadier feeding, and longer-lasting results.

Liquids are ideal for supplemental feeding or foliar correction, but granular fertilizers build lasting soil fertility and balanced nutrition throughout the root zone.

Ease of Use

Granular fertilizers are simple to apply. Use a broadcast or rotary spreader, apply evenly, and water in thoroughly to activate nutrients. There’s no mixing, measuring, or spraying required. For best results, see our Spreader Settings Guide for each product.

Frequently Asked Questions

What does N-P-K mean on fertilizer?

N-P-K stands for Nitrogen, Phosphorus, and Potassium — the three primary nutrients plants need for growth, roots, and overall health.

Why choose granular over liquid fertilizer?

Granular fertilizer provides more nutrients per pound, longer feeding, and complete nutrition. Liquid fertilizers are limited by how much nutrient can be dissolved and typically need frequent reapplication.

How do I apply granular fertilizer?

Use a broadcast spreader for even coverage, then water in thoroughly. See our Spreader Settings Guide for rates and calibration tips.

Which granular fertilizer should I use?

For general lawn feeding, use Almighty 20-0-10 or Emerald 10-0-20. For new seed, use Starter 15-20-10. For low-nitrogen maintenance, use NutriGreen 0-0-4 or BioBoost 5-3-0. For ornamental and tropical plants, use Palm & Tropicals 8-10-10 or Elite Plant 14-14-14.

How do I correct specific nutrient deficiencies?
