Simple Lawn Solutions 15-0-15 Liquid Fertilizer 1 Qt — Phosphate-Free Lawn Food with Humic Acid & Kelp for Faster Greening

Simple Lawn Solutions 15-0-15 is a concentrated, phosphate-free liquid fertilizer formulated to quickly boost turf color and vigor using a 15-0-15 nitrogen-potash blend plus humic acid and kelp extracts.

This one-quart liquid lawn food supplies readily available nitrogen and potassium to support greener blades and improved turf hardiness without adding phosphorus. It combines fast-acting nutrients with humic acid derived from leonardite and kelp seaweed to promote nutrient uptake and help lawns recover from deficiencies. Suitable for all grass types and usable with common sprayers, the formula is produced in the USA and crafted for both residential and commercial turf care.

How does this fertilizer improve color and growth?

The 15% nitrogen component feeds chlorophyll production to intensify green tone and encourage shoot development, while the humic acid helps roots access those nutrients. Applied correctly, you'll see quicker color response than with many granular products because liquid nutrients are immediately available.

• 15% nitrogen for rapid greening and lush leaf expansion
• Humic acid to enhance root nutrient absorption
• Liquid form provides faster uptake than many granules

Will this product help my lawn handle stress and poor soils?

Potassium (15%) supports physiological functions that aid plant endurance under stress, and the formula's humic and kelp components improve soil conditions and microbe activity. It's especially useful on sandy or low-organic soils where nutrient retention is limited.

• 15% potassium to support stress resilience and enzyme activity
• Humic acid improves soil structure and microbial interactions
• Good option for sandy lawns that need quicker nutrient replenishment

How should I apply it and what equipment works best?

Simple Lawn Solutions 15-0-15 is designed for versatile application. Use a hose-end sprayer, pump-up sprayer, backpack sprayer, or watering can; dilute and apply according to label directions for lawns, ornamentals, or potted plants to ensure even coverage and avoid runoff.

• Compatible with hose-end, backpack, or pump-up sprayers
• Can be used as a supplement to granular programs for quick uptake

Is this safe for all grass types and compatible with existing programs?

The phosphate-free 15-0-15 formula is suitable for a wide range of turf varieties including Bermuda, St. Augustine, Zoysia, Bluegrass and more. It can be integrated into an existing fertilization schedule as a liquid supplement to address nitrogen or potassium deficiencies quickly.
