Fish emulsion is a liquid fish fertilizer made from byproducts of the fishing industry. It is beneficial for leafy vegetables and fruits that we grow. It is high in nitrogen and sold as a concentrated liquid which gardeners dilute and use. It has a typical fishy smell but now-a-days, deodorized versions are available easily.

What Ingredients and Nutrients Are In Fish Emulsion?

We all are aware that the fertilizers have the ingredients Nitrogen, Phosphorus and Potassium and is denoted in ratio of number N:P:K. This ratio tells the percentage by weight of each of these three elements.

Generally, fish emulsion fertilizers have a ratio of 5 :2:2 or 5:1:1. These liquid fertilizers may provide the ingredients which your soil might lack and are necessary for a rich and balanced growth in your garden.

Fish emulsion also provides:

  • Calcium
  • Magnesium
  • Sulphur
  • Chlorine
  • Sodium

… which plants require in micro quantities.

How Do You Use Fish Emulsion In The Garden?

You’ll need:

  • A bottle of fish emulsion (either store bought or home-made)
  • A clean bucket

The procedure is very simple. For every 1 gallon of water mix 3 tablespoons of the fish emulsion concentrate. Increase this quantity with the number of gallons water you will be using.

That’s all there is to it. Your fish fertilizer is ready to go.

In the garden, apply the fertilizer as you would a liquid fertilizer by watering plants with the solution. It’s recommended to use around 1/2 gallon per tomato plant for example. [source]

As simple as the process is of using fish emulsion, there are reasons for using organic fish emulsion fertilizer over other fertilizers.

  • Organic fish emulsions are produced from unused fish parts, and are natural resources which will otherwise be wasted.
  • They contain ample Nitrogen- Phosphorus- Potassium which are essential plant elements.
  • The micronutrients like Calcium, Magnesium, Sodium etc. which are constantly replenished and needed by plants.
  • Fish emulsion can be used at any point of time as an all-purpose fertilizer.
  • They are mild and there is less chance of damaging/ burning the plants.
  • It can be used as a soil drench as well as a foliar spray.
  • They are beneficial to the plant but do not cause any harm and contamination of the environment like the chemical varieties.

The nutrients supplied by fish emulsions make the plants stronger and pest resistant. The addition of lavender oil has helped take the fishy smell out with a deodorized option is available.

One additional benefit of fish emulsion is, that plants will not be overfeed.

The nutrients help increase soil health and soil microbes.


How Often Should The Fish Emulsion Be Applied?

Since the fertilizer acts fast on providing nutrients, more frequent applications are required.

Many plants grown outdoors are watered twice per week. Research has shown, that the application of half ounce of fish emulsion mixed with one-gallon water applied twice weekly helped plants grow vigorously.

Check The Percentages

Before feeding plants with fish emulsion, always check the nutrient levels currently present in the soil to avoid over feeding. Follow the instructions on the packet, if using store brought emulsions.
