How to Crush Bone to Make Bone Meal


Bone meal is a popular organic fertilizer for gardens and flower beds, consisting of the ground-up bones of livestock. It contains nitrogen and phosphorous to nourish plants, as well as calcium, an important mineral for perennials. In addition, it is a natural slow-release fertilizer, releasing nutrients into the soil as the bone decomposes. It is a relatively simple task to make your own bone meal using leftover bones from cooking.

Things You'll Need

  • Oven
  • Heavy canvas bag
  • Rolling pin or meat tenderizer
  • Blender or coffee grinder
  • Clean the meat and fatty tissue from leftover bones. If you can't remove all the tissue by scraping, boil the bones until they are clean.

  • Bake the bones at 400°F until they are thoroughly dry and brittle, about an hour for most small to medium bones. Set aside until cool.

  • Place the bones in a heavy tear-proof sack, preferably canvas. Using a rolling pin or meat tenderizer, smash the dried bones into fragments no larger than 1 inch.

  • Grind the bones in a coffee grinder or blender set to pulse.

Tips & Warnings

  • A coarse bone meal will release its nutrients more slowly, while a fine powder will break down more quickly, providing a more powerful but short-lived nutrient boost.
  • Bone meal may be added to your compost heap or mixed directly with the soil around the base of your plants.
  • Poultry bones are easier to crush and grind than beef or pork bones. Keep this in mind if you lack a powerful blender or grinder.
  • Don't attempt to smash or crush bones without enclosing them in a tear-proof sack. Flying bone fragments can cause serious damage to the eyes and can even nick unprotected skin.
