How to Make Organic Fish Emulsion Fertilizer

1. Liquefy the fish and or seaweed by placing it in a blender with warm water and blending thoroughly until you've created an emulsion.

2. Pour the fish emulsion into a 5 gallon bucket. Be sure to use a bucket that has a lid which can be sealed tightly.

3. Add shredded newspapers, dried leaves, sawdust or brown grass clippings to the bucket to feed your fish emulsion fertilizer as it decays.

4. Pour molasses into the bucket to control odor and contribute healthy microorganisms to your organic fish emulsion fertilizer.

   Fish Heads Can Be Used As Fertilizer

   Open the bucket each day and stir the fish fertilizer. Opening the bucket also helps "burp" the fish emulsion as it's decaying.

6. Wait 2 weeks until the entire mixture has turned dark brown before using. If you want to get rid of the fishy odor, you can add brown sugar, molasses or pureed fruit to the mixture and ferment a few days longer.

Tips & Warnings

• Dilute the fish fertilizer and use a hose end sprayer to distribute it to your garden.
• Just because it's made from food doesn't mean you can eat it. Fish emulsion fertilizer is not to be consumed by humans.
