A fish-based organic liquid fertiliser with an NPK of 5-1-1, providing nitrogen-rich nutrition for healthy plant growth indoors and outdoors.

Arctic Fish Fertiliser is a concentrated liquid plant feed made from fish-derived organic matter. With an NPK ratio of 5-1-1, it provides a nitrogen-led nutrient profile that makes it particularly useful for supporting healthy vegetative growth.

Fish has a long history of use as a natural source of plant nutrition. As the organic matter in Arctic Fish breaks down within the growing medium, nutrients become available to plants while the organic material contributes to a biologically active root environment.

Suitable for a wide range of indoor and outdoor plants, Arctic Fish offers growers a straightforward way to incorporate a fish-based organic fertiliser into their regular plant feeding programme.

Why choose Arctic Fish Fertiliser?

  • NPK 5-1-1 – a nitrogen-rich nutrient profile suited to supporting healthy vegetative plant growth.
  • Fish-based fertiliser – supplies plant nutrition from a natural source of organic matter.
  • Supports soil biology – organic matter provides a food source for microbial life as it breaks down in the growing medium.
  • Indoor and outdoor use – suitable for feeding a broad range of plants in different growing environments.
  • Versatile plant nutrition – suitable for plants, vegetable gardens, roses, trees and shrubs.
  • 5 litre size – a practical larger-volume option for growers feeding plants regularly.

What is Arctic Fish Fertiliser suitable for?

With an NPK of 5-1-1, Arctic Fish has considerably more nitrogen than phosphorus or potassium. That makes it particularly useful during periods when plants are actively producing leaves, stems and other vegetative growth.

It can be used with a broad range of indoor and outdoor plants, including ornamental plants, vegetable gardens, roses, trees and shrubs. This versatility makes it useful for growers who want a fish-based liquid fertiliser that can be used across several different plant types.

Arctic Fish is also well suited to soil-focused growing programmes where organic matter and biological activity form an important part of the approach to plant nutrition.

How to use Arctic Fish Fertiliser

Shake the bottle thoroughly before every use. Natural separation can occur while fish fertiliser is standing in storage, so thorough mixing helps ensure the product is evenly distributed before measuring.

Dilute Arctic Fish Fertiliser with water according to the application instructions on the product label and the requirements of the plants being grown. Mix thoroughly before applying the prepared feed.

When incorporating Arctic Fish into an existing feeding programme, take the nutrients already being supplied into account rather than treating every fertiliser as an isolated addition. Its 5-1-1 analysis means Arctic Fish makes a meaningful contribution to the nitrogen supplied to the crop.

Store the container securely with the cap firmly closed and shake thoroughly again before the next application.

Ingredient separation can occur naturally while the product is standing in storage. Shake the bottle thoroughly before use so the contents are properly mixed before measuring and diluting the fertiliser.

Does Arctic Fish Fertiliser support soil microbes?

Fish fertiliser introduces organic matter into the growing medium. As this material breaks down, it provides a food source for microbial activity within biologically active soils and growing media.

Is Arctic Fish Fertiliser a flowering booster?

Arctic Fish is better described as a general fish-based fertiliser with a nitrogen-led NPK of 5-1-1 rather than a dedicated high-phosphorus or high-potassium flowering booster.
