Neptune's Harvest Hydrolyzed Fish Fertilizer

• OMRI Listed 2-4-1 Organic
• From North Atlantic Fish
• Low-Odor Formula 
• For Houseplants, Gardens, Lawns, And Compost

Neptune’s Harvest Hydrolyzed Fish Fertilizer 2-4-1 is an all-in-one natural liquid feed for steady growth. It’s made from fresh North Atlantic fish using a cold process that helps protect naturally occurring compounds like amino acids and enzymes, and the nutrients are in forms plants can take up readily. Unlike many fish emulsions, it retains the fish proteins and oils and is known for being far less offensive in odor, which makes it easier to use around patios, greenhouses, and indoor plant areas. Our growers use it on new transplants, aged containers, or beds that need consistent nutrition.

This fertilizer is flexible. Use it as a soil drench to feed roots and support the soil biology, or as a foliar spray when you want quick uptake during active growth. The 2-4-1 analysis gives a balanced approach for greens, roots, and overall plant performance across vegetables, flowers, fruit, trees, and container gardens.
