How to Make Fish Fertilizer

Fish fertilizer is fairly easy to make.

There are 6 steps, ranging from easy to queasy, but in the end, you will  have a super food that your plants will LOVE!

Make Your Own Fish Fertilizer

Here are the steps:

  1. Dig some worms, then grab your fishing rod and a bucket with a tight fitting lid. If you don’t fish, find someone who does and ask for their left-over fish guts.  Yes, they will look at you like you’re crazy, but carry on and skip to step 4.
  2. When you get to your favorite lake, put some lake water in your bucket, catch 3 or 4 fish (Sunfish work well in our area) and add them to the water in your bucket.  If you catch some weeds, like I usually do, put those in too.
  3. Enjoy the rest of the day fishing, listening to the birds and feeling the sun and breeze on your face.
  4. Go home with your fish bucket.
  5. Here comes the queasy part…grab a hatchet and chop up your fish.  I take the fish out of the bucket place them on the ground, near my compost heap and chop away.  Once you get past the first fish, the rest won’t seem so bad…..until you get splashed with fish guts.  Might want to wear goggles.  I’m just saying.
  6. Shovel your chopped fish back into your bucket.

Now we’re ready for the Fish Fertilizer Recipe

  • Lake water (about a gallon)
  • 3 or 4 fresh chopped fish
  • Browns…leaves, dead grass, sawdust (enough to soak up the water)
  • Molasses…about 1 cup (helps the mix ferment and keeps the stink down)
  • Epsom Salt…2 tablespoons to add some magnesium
  • Let it ferment for about 1 month, stirring or shaking the mix every 3 days.
  • After a month, it will be ready to use as a tea.
  • To make a tea, put 1 part fertilizer to 5-6 parts water in a bucket or watering can.  Let this set for about a week, stirring every day.  When you are ready to apply the fish fertilizer tea, water your plants a bit first, (just in case the tea is a little too strong) and then apply the fertilizer to the base of your plants.

After that, just set back and watch your plants grow!
