Neptune’s Harvest Fish Fertilizer 2-4-1 Organic Fertilizer

Neptune’s Harvest Fish Fertilizer 2-4-1 is an OMRI Listed organic fertilizer made from dock-fresh North Atlantic fish using a cold-process hydrolysate method. Unlike traditional fish emulsions that are often heat-processed, this premium liquid fish fertilizer helps preserve naturally occurring proteins, amino acids, vitamins, oils, trace elements, and plant-supporting compounds for complete organic plant nutrition.

This concentrated 2-4-1 formula is ideal for vegetables, herbs, flowers, fruiting plants, seedlings, transplants, houseplants, trees, shrubs, lawns, containers, raised beds, and hydroponic or soil-based gardens. Neptune’s Harvest Fish Fertilizer can be used as a soil drench or foliar spray to support strong roots, healthy foliage, improved soil biology, and vigorous overall plant growth.
