Biologically active with beneficial probiotics, indigenous microorganisms, and mycelium to support healthy plant growth.

Discover Fermented Fish Fertilizer by Fierce Fish

Fierce Fish Fertilizer was created to fulfill a need for a more balanced soil web. Through multiple years of experimentation, we have developed our concentrated formula soil soak. Our product is 100% natural –  if it’s not grown/caught/fermented, or foraged, it’s not included.

The Benefits

The health and wellbeing of the planet and all living things on it start in the soil.

Plant growth needs a multitude of minerals and other supports to reach its maximum health. A healthy soil web, filled with indigenous microorganisms and mycelium, support plant roots and structure, thereby increasing nutrient availability in the plant. This equals a larger, healthier plant, higher in nutrient levels to ultimately increase your own bodys health levels when you eat it. All of the fish we use is sustainably sourced wild Pacific bycatch, or other fish that cannot be marketed for human consumption. 

The Gardens & Results

Using Fierce Fish Fermented Fish Fertilizer in association with an active mulching program will increase the yields and overall health of your plants and crops. Store in a cool dark location (biologically active), and vent cap upon delivery to relieve expansion of natural gases.
