6 Best Fish Fertilizers For your Garden

Rich in organic matter and essential oil, fish fertilizer can be moderately used at almost any stage of plant growth. It packs a lot of bacteria and fungi compared to chemical fertilizers that help to boost the content of Nitrogen, improve soil health, and increase its fertility. Unlike chemical fertilizers, fish fertilizer prevents soil from hardening and losing essential oil after each use.

You can mostly find three different types of best fish fertilizer in the market.

• Fish Emulsion
• Fish Meal
• Hydrolyzed Fish Fertilizer

Fish meal is a slow-release fertilizer compared to Fish emulsion and Hydrolyzed Fish fertilizers. The latter two are liquid-based fertilizers.
