Neptune’s Harvest Fish & Seaweed Blend 2-3-1 is a premium organic liquid fertilizer that combines hydrolyzed North Atlantic fish with cold-water kelp to support strong roots, lush foliage, abundant blooms, and overall plant vigor. This powerful fish and seaweed formula provides a balanced mix of nutrients, trace minerals, amino acids, vitamins, and naturally occurring plant-supporting compounds for healthier growth from seedling to harvest.

Ideal for vegetables, herbs, flowers, fruiting plants, houseplants, trees, shrubs, containers, raised beds, and garden beds, Neptune’s Harvest Fish & Seaweed Blend can be applied as a soil drench or foliar spray. Its cold-enzyme hydrolysis process helps retain valuable fish proteins and oils while reducing the strong odor commonly associated with traditional fish emulsions.
