Alaska Fish Fertilizer 5-1-1 is a fish-based fertilizer used for organic gardening, made to support plant strength and vigor in vegetable and flower gardens. This fish emulsion fertilizer brings a classic, natural source of plant nutrients into modern indoor and outdoor plant care.
Used for centuries as a plant nutrient source, fish-based inputs are valued for how they contribute to soil health over time. Alaska Fish Fertilizer provides a rich source of organic matter that breaks down in the soil and releases nutrients as it does. That organic matter focus supports a healthier growing environment, because naturally occurring soil microbes thrive and work their best in soil that is rich in organic matter. For growers who care about both plant performance and soil life, this is one of the key reasons fish emulsion fertilizer stays a staple.
This OMRI listed fertilizer is positioned for a wide range of plant types and garden spaces. It’s intended for vegetable, fruit, and flower gardens, and it’s also described as excellent for flowers, trees, and other plants. If your yard or greenhouse includes perennials, shrubs, and trees, the product is specifically called out as working best in those categories. It’s also presented as great for all indoor and outdoor plants, which makes it easy to keep one familiar organic gardening fertilizer on hand for both houseplants and outdoor beds.
The nutrient profile is straightforward: 5-1-1. The formula is derived from fish solubles and phosphoric acid, and it is stabilized with sulfuric acid and phosphoric acid. Alaska Fish Fertilizer is also described as a gentle option that won’t burn plants, which helps when you want an all-purpose fish-based fertilizer that stays practical across many plant types without feeling harsh.
Alaska Fish Fertilizer 5-1-1 is a good fit for gardeners who want an OMRI listed fish emulsion fertilizer for organic gardening that supports strength and vigor, encourages active soil microbes, and works across indoor and outdoor plants in vegetable, fruit, and flower gardens.
