Why customers choose Cera Garden
Overview
Neptune’s Harvest Organic Fish Fertilizer 2-4-1 is a versatile, organic liquid plant food designed for vegetables, flowers, fruit, trees, lawns, and indoor plants. Produced through a distinctive cold‑process that preserves vitamins, amino acids, enzymes, and growth hormones drawn from clean North Atlantic fish, it avoids lake, farmed, or river fish.
Beyond simple NPK values, this fish hydrolysate delivers a broad spectrum of micronutrients, vitamins, minerals, amino acids, enzymes, and omega oils. The result is nutrition that supports plant metabolism and overall vitality while minimizing the odor often associated with other fish‑based products.
Key benefits and what you might notice
- Complete nutrition beyond NPK, including micronutrients and trace elements
- Derived from 100% ocean fish using a careful cold‑process method
- Contains omega oils, amino acids, enzymes, and growth hormones in natural balance

How to use
Mix at the recommended rate and apply as a soil drench or foliar feed. In most setups, one ounce per gallon of water is sufficient. It is suitable for indoor plants as well as outdoor gardens, trees, lawns, and vegetables, and it can act as a natural sticker and spreader to improve nutrient adherence.
- Indoor plants: dilute and spray or water into the root zone
- Outdoor spaces: apply to vegetables, flowers, fruit trees, and lawn edges
- All-in-one tool: works as a soil conditioner and plant food while supporting soil life
