Collection: Fish Fertilizers

Support plant health, foster root growth, and enrich soil health with our selection of organic fertilizer products derived from natural fish. From fast-acting liquid fish fertilizer to slowly releasing meals, we offer solutions for both indoor and outdoor plants, and we maintain a range of fish fertilizer for sale to suit different needs.

Why Choose Fish-Based Fertilizer?

Fish fertilizer delivers nutrients such as nitrogen, phosphorus, and potassium, along with amino acids, which work together to boost plant growth and improve microbial activity in your soil. Unlike chemical fertilizers, fish-based products feed plants gently while building long-term fertility—ideal for organic gardening.

Some of our offerings carry OMRI listed status for growers requiring certified organic inputs.

Types of Fish Fertilizers We Offer

Liquid Fish Fertilizer

Our liquid fish options are highly soluble and ideal for foliar sprays or fertigation:

• Fish emulsion fertilizer: A liquid fertilizer made from fish scraps, commonly used for outdoor plants due to its odor.
• Fish hydrolysate: Cold-processed liquid fish that retains more nutrients and amino acids, providing a richer plant food.
• Dilute with a gallon of water for application.
• Available in container sizes up to 128 oz, 5-gallon, and larger formats.

Dry Fish-Based Fertilizer

For sustained feeding, our dry options are ideal:

• Fish Meal (50 lb): Made from dried fish scraps, ideal for steady nitrogen release and overall plant growth.
