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

Most fish emulsions use a 5-1-1 ratio, which provides a balanced boost of nitrogen for leafy growth and modest phosphorus and potassium for root development. If you need a higher nitrogen boost for fast‑growing vegetables, a 12-2-2 powder can be a better choice, while a 2-3-1 liquid is ideal for light, frequent feeding. Consider the specific needs of your plants and the stage of growth when selecting the ratio.

Liquid emulsions, such as the 1‑gallon Alaska or Liquinox products, are ready to dilute and apply, making them convenient for regular foliar sprays or soil drenches. Powdered options like the 12-2-2 fish protein powder are more concentrated, reducing storage space and odor, and can be mixed to cover large areas up to 300 gallons. Choose liquid for ease of use and quick results, or powder for lower odor and cost‑effective large‑scale applications.

Traditional fish emulsions have a strong fishy smell, but some brands add deodorizing agents, such as the wintergreen scent in Alaska Fish Emulsion. Powdered formulations, like the 12-2-2 fish protein powder, naturally emit less odor because the drying process reduces volatile compounds. If scent is a priority for indoor gardening, opt for deodorized liquids or powders.

Larger containers, such as the 1‑gallon or 32‑oz bottles, typically offer a lower cost per ounce compared to 8‑oz or quart sizes. For example, the 1‑gallon Alaska Fish Emulsion and the 32‑oz B0DQQPH29R provide more feed for the price, especially when used for multiple garden beds. Calculate the total amount of feed needed per season and compare the price per gallon to determine the most economical option.

Yes, most fish emulsions are safe for indoor, outdoor, and even hydroponic setups, provided you follow the recommended dilution rates. Products like Fertilome 5‑1‑1 and Liquinox list specific mixing instructions for containers, lawns, and trees, making them versatile. Always ensure proper ventilation when using strong‑smelling liquids indoors.

Complete fish emulsions, such as the 8‑oz B0DQR1X69R, provide a straightforward source of nitrogen, phosphorus, and potassium from fish alone. Blended formulas, like the EB Stone Fish Emulsion with Kelp, add extra micronutrients and organic matter that can enhance soil biology and improve fruiting. If your soil test shows micronutrient deficiencies, a blended product may give you added benefits.

Look for labels indicating the fertilizer is non‑burning and safe for edible plants, such as the “Will Not Burn” claim on Alaska Fish Emulsion. Products that include iron, manganese, and zinc, like Liquinox, provide additional trace nutrients without harming sensitive foliage. Always read the usage instructions to avoid over‑application, which can lead to leaf tip burn.

Fish emulsions are typically applied every 2‑4 weeks during the active growing season, using the recommended dilution (e.g., 1‑2 tbsp per gallon of water for foliage). For larger trees, a stronger mix of 4 tbsp per gallon is suggested. Regular, light applications promote steady growth and improve soil microbial activity without overwhelming the plants.
