Comparison: Best Fish Emulsion For Grass (Updated | Dec 1st)

For grass, a balanced ratio like 5-1-1 or 2-3-1 provides enough nitrogen for vigorous green growth while keeping phosphorus and potassium low enough to avoid excess root growth. Higher nitrogen ratios, such as 12-2-2, can boost rapid greening but may lead to nutrient imbalances if over‑applied. Choose a formula that matches your lawn’s soil test results and desired growth speed.

Liquid concentrates, like the 1‑gallon Alaska Fish Emulsion or Liquinox, are easy to mix and apply with a garden sprayer, making them convenient for frequent, light feedings. Powdered options, such as the 12‑2‑2 fish protein powder, are highly concentrated and can cover up to 300 gallons of water, which is cost‑effective for extensive areas. However, powders require thorough mixing to avoid clumping and may have a milder odor than some liquids.

Yes, traditional fish emulsions can have a strong fishy smell, which some homeowners find unpleasant. Products like the Alaska Fish Emulsion are deodorized with natural wintergreen, while the powder formulation advertises reduced odor. If scent is a concern, opt for a low‑odor or deodorized liquid, or use the powder and dilute it well before application.

Kelp provides additional micronutrients, hormones, and trace minerals that enhance root development and stress tolerance. The EB Stone Fish Emulsion with Kelp combines these benefits with the nitrogen boost from fish, offering a more comprehensive feed for lawns. This blend can improve overall plant vigor, especially in soils that lack organic matter.

A 5‑1‑1 ratio emphasizes nitrogen, ideal for lawns that need rapid greening and thickening. A 2‑3‑1 ratio supplies more phosphorus, supporting root growth and overall plant health, which can be advantageous for newly seeded or stressed lawns. Consider your lawn’s current condition and soil test results to choose the most appropriate balance.

Most fish emulsions are organic and non‑burning, making them safe for edible gardens and lawns when used as directed. Ensure proper dilution—typically 1‑2 tablespoons per gallon of water for lawns—to avoid over‑application. Keep children and pets off the treated area until the solution has dried, especially with liquid concentrates that may be slippery.

For a medium‑sized lawn, the 1‑gallon Alaska Fish Emulsion provides a good balance of concentration, deodorization, and price per gallon, covering regular feedings without excessive odor. The 32‑ounce Fertilome 5‑1‑1 offers a lower upfront cost but requires more frequent refills. If you prefer fewer purchases, the 12‑2‑2 powder, which stretches to 300 gallons, delivers the highest volume per dollar, though it needs careful mixing.

Yes, most fish emulsions are versatile and safe for lawns, garden beds, and vegetable crops when diluted correctly. Look for products labeled safe for edible plants, such as the Fish Hydrolysate Fertilizer (2‑3‑2) or the complete fish emulsion options. Always follow the manufacturer’s application rates to avoid nutrient excess that could affect vegetable flavor or yield.
