Dirt N Grow Evolve Fish Grow 3-1-1 is a concentrated liquid organic fertilizer for soil, made to support soil micro-organisms and build a healthier soil system for healthy plants.
This liquid organic fertilizer is designed for growers who care about soil life as much as top growth. The “healthy soil equals healthy plants” idea is built into what Fish Grow is: a soil health fertilizer that focuses on nurturing the biology that supports plant performance. If you prefer a simple, bottle-based approach, this concentrated liquid fertilizer delivers a clear, no-frills role in your garden toolkit.
Evolve Fish Grow is a 3-1-1 fertilizer, stated once for shoppers who compare formulas by nutrient profile. Beyond that, the core of the product is the inputs that support soil activity. It is made from fish and vegetable proteins, described as a food source for micro-organisms. By supporting soil micro-organisms and helping increase their population in the root zone, Fish Grow is positioned to keep your soil system more active and resilient, which is exactly what many gardeners want when consistency matters.
The product is also built for real-world handling. The bottle has a flip top trap cap, a small detail that makes day-to-day dispensing cleaner and more controlled without adding extra parts or gimmicks. That practical design matches the product’s overall intent: straightforward garden support, with the focus on soil biology, not on complicated programs or extra steps.
Dirt N Grow Evolve Fish Grow 3-1-1 is a good fit for gardeners who want a liquid plant nutrient that supports soil micro-organisms, aims for a healthier soil system, and keeps the message simple: healthy soil equals healthy plants, with a concentrated liquid fertilizer format that stays easy to keep on hand.
Step-by-step mixing and feeding instructions for Dirt N Grow Evolve Fish Grow 3-1-1 - 4 Litre.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Dirt N Grow Evolve Fish Grow 3-1-1 - 4 Litre well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

Warning – Important Safety Information
This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.
General safety precautions
Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.
Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.
First aid – skin contact
IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.
First aid – eye contact
IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.
First aid – ingestion and inhalation
IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.
IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.

| Total Nitrogen (N) | 3.0% |
|---|---|
| Available Phosphate (P2O5) | 1.0% |
| Soluble Potash (K2O) | 1.0% |
| Calcium (Ca) | 0.5% |
Available Phosphate (P₂O₅) supports root development, energy transfer, and early structural growth by providing a form of phosphorus that plants can absorb and use quickly.
Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.
Fish protein provides a slow, biology-driven nitrogen supply that supports steady leaf and stem growth while also feeding root-zone microbes that unlock nutrients over time. It’s unique because plants don’t use the protein directly, so it releases more gradually than fast nitrogen sources, which can reduce sudden burn but requires an active, well-aerated root zone to work well.
Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.
Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.
Vegetable protein acts like a hybrid: it can contribute gentle organic nitrogen, but its unique value is how it supports root-zone biology and stress recovery through amino acids and peptides, which is different from purely mineral fertilizers that mainly deliver salts and quick growth.
