Grow with confidence using Neptune’s Harvest Fish Fertilizer (2-4-1)

Designed to work with nature, this organic liquid plant food is produced through a careful cold process that protects essential vitamins, amino acids, enzymes, and growth hormones. The formula uses clean North Atlantic ocean fish and never utilizes lake, farmed, or river fish. It supports lawns, vegetables, flowers, and indoor plants throughout the growing season and remains safe for households with kids and pets when used as directed.

What makes this fertilizer special

  • Cold-processing preserves vitamins, amino acids, enzymes, and growth hormones for robust, balanced nutrition.
  • Derived from 100% fish hydrolysate, delivering a broad nutrient balance that goes beyond NPK, including micronutrients and omega oils.
  • Sourced from clean North Atlantic fish, never from lake, farmed, or river fish, for a natural nutrient profile.
  • OMRI Listed, designed to support soil health over time without harsh synthetic additives.
  • Safe for homes with kids and pets when used as directed.

How to use and what to expect

  • Mix just one ounce of Neptune’s Harvest per gallon of water, then apply as a soil drench or foliar feed.
  • Suitable for indoor plants, outdoor gardens, trees, lawns, and vegetables, acting as a natural sticker and spreader to improve nutrient uptake.

Soil health and long-term benefits

  • Aims to build organic matter and feed beneficial bacteria and microbes, helping soil structure, moisture retention, and drainage.
  • May raise Brix levels in plants and can contribute to carbon sequestration over time.
  • Could help plants become less susceptible to pests and disease through improved vigor and nutrient density.

Why choose fish-based nutrition? Plants often respond quickly to readily available nutrients from fish hydrolysate, potentially promoting greener foliage, more uniform flowering, and stronger root systems throughout the season. The product is noted for a milder odor compared to traditional fish emulsions, making it more pleasant for home gardens.
