New! Neptune's Harvest Hydrolyzed Fish Fertilizer 2-4-1

Contains all the micro and macro nutrients naturally found in fish.

This organic fertilizer is made from fresh North Atlantic fish using a unique cold process that protects the vitamins, amino acids, enzymes and growth hormones. The nitrogen and other nutrients are chelated, so they are readily available for plants consumption.

Unlike fish emulsions, Neptune's Harvest retains the fish proteins and oils and has no unpleasant odor. University studies have shown Neptune's Harvest to outperform chemical fertilizers.

Tested and proven with excellent results by many gardeners. Neptune's Harvest All Natural Organic Fertilizers and Amendments are OMRI listed for use in organic growing.
