Simple Lawn Solutions 16-4-8 Liquid Lawn Fertilizer 32 oz — Concentrated NPK Spray with Seaweed & Fish for Greener, Healthier Turf

Simple Lawn Solutions 16-4-8 is a concentrated liquid lawn food that supplies balanced macronutrients (Nitrogen-Phosphorus-Potassium) plus seaweed and fish to support greener, healthier turf when used as directed.

Designed as an all-in-one maintenance fertilizer, this 32-ounce spray formula delivers a 16-4-8 NPK ratio in a ready-to-apply liquid. The blend is made from feed-grade ingredients and includes organic amendments (seaweed and fish emulsion) to help improve nutrient uptake. It’s produced in the United States and formulated to work on the major turfgrasses homeowners and professionals use, including warm- and cool-season varieties.

What does the 16-4-8 ratio mean for my lawn?

The numbers indicate the percentage of key macronutrients: 16% nitrogen, 4% phosphorus, and 8% potassium. Nitrogen supports leaf growth and color, phosphorus helps root development, and potassium aids overall plant function and stress tolerance. Together they form a balanced maintenance feed suitable for established turf.

• 16% Nitrogen for greening and encouraging dense turf growth
• 4% Phosphorus to support root strength and recovery
• 8% Potassium to assist water regulation and resilience
• Seaweed and fish emulsion to add organic nutrients and improved uptake

How do I apply this liquid fertilizer safely and effectively?

Apply according to label directions and ensure the lawn is adequately watered before and after application for proper nutrient movement. Because it is concentrated, measure carefully and use the recommended sprayer or hose-end applicator to achieve even coverage. Avoid application during extreme heat or drought to reduce stress on turf.

• Use the product in a calibrated sprayer or hose-end applicator for even distribution
• Water lightly after application to move nutrients into the root zone
• Follow frequency guidelines on the label for maintenance feeding schedules
• Store upright in a cool, dry place away from children and pets

Will this work on my grass variety?

16-4-8 is formulated for broad compatibility and can be used on most common turf species. The label lists warm-season and cool-season grasses such as Bermuda, St. Augustine, Zoysia, Bahia, Fescue, Ryegrass, and Kentucky Bluegrass. Always check the product label for any specific restrictions for newly seeded or recently sodded lawns.

• Suitable for both warm-season and cool-season grass types
• Appropriate for established lawns needing routine maintenance
• Check label for guidance on use with young or newly installed turf
• Can be incorporated into regular seasonal feeding programs

What additional benefits come from the seaweed and fish ingredients?

Seaweed and fish emulsion add organic-derived micronutrients and biological matter that support soil biology and enhance nutrient availability. These components don’t replace a soil test but can complement macronutrient feeding by improving nutrient uptake and microbial activity in the root zone. They are included at measured levels appropriate for a liquid lawn feed.

• Provides organic matter to support soil biology
• Helps improve nutrient absorption by turf roots
• Delivered in a readily usable liquid form for even application
• Formulated with feed-grade ingredients for consistency

Who is this for: Simple Lawn Solutions 16-4-8 is best suited for homeowners and small-property professionals who want a straightforward, concentrate liquid fertilizer to maintain an established lawn. It’s useful for property owners who prefer a balanced NPK maintenance feed that also includes organic additives, and for those managing common warm- and cool-season grasses. For newly seeded lawns, specific soil deficiencies, or professional sports turf programs, pair this product with soil testing and customized nutrient plans.
