How To Make Bonemeal

If you’re looking to make your own fertilizer for your garden, bonemeal may be just the thing for you. Bonemeal is a nutrient-rich substance that is made from ground-up animal bones. It is an excellent source of phosphorus and calcium, which are both essential nutrients for plant growth. In this article, we will show you how to make bonemeal in a few easy steps.

What You Will Need

To make bonemeal, you will need a few basic supplies. These include:

  • Bones (chicken, beef, or fish)
  • A large pot
  • A grinder or blender
  • A fine mesh strainer
  • A baking sheet
  • An oven

Step 1: Collect Bones

The first step in making bonemeal is to collect bones. You can use bones from chicken, beef, or fish. If you are using bones from chicken or beef, you can collect them from your local butcher or grocery store. If you are using fish bones, you can collect them from a fish market or seafood restaurant.

Step 2: Clean the Bones

Once you have collected your bones, you will need to clean them. Rinse them thoroughly under running water to remove any dirt or debris. If you are using fish bones, you may want to soak them in water for a few hours to remove any fishy odor.

Step 3: Boil the Bones

Next, you will need to boil the bones. Place them in a large pot and cover them with water. Bring the water to a boil and let the bones simmer for about an hour. This will help to soften the bones and make them easier to grind.

Step 4: Dry the Bones

After the bones have boiled, you will need to dry them. Preheat your oven to 200 degrees Fahrenheit. Place the bones on a baking sheet and put them in the oven for about 3-4 hours, or until they are completely dry. You can also let them air dry, but this will take longer.

Step 5: Grind the Bones

Once the bones are dry, you will need to grind them. You can use a grinder or blender to do this. Grind the bones until they are a fine powder. This may take a few minutes.

Step 6: Strain the Bonemeal

After you have ground up the bones, you will need to strain the bonemeal. Use a fine mesh strainer to remove any large pieces of bone that may be left. You want the bonemeal to be a fine powder.

Step 7: Store the Bonemeal

Finally, you will need to store the bonemeal. Place it in an airtight container and store it in a cool, dry place. It will keep for several months.


What plants benefit from bonemeal?

Bonemeal is a great fertilizer for plants that need a lot of phosphorus and calcium, such as tomatoes, peppers, and squash.

Can you use bonemeal on indoor plants?

Is bonemeal safe for pets?

Bonemeal is generally safe for pets, but it can be toxic in large amounts. Be sure to keep it out of reach of pets.


Now that you know how to make bonemeal, you can create your own nutrient-rich fertilizer for your garden. It’s a simple and cost-effective way to give your plants the nutrients they need to grow strong and healthy. So give it a try and see the difference it can make in your garden.
