How To Make Bone Meal

Bone meal is a popular fertilizer that has been used by farmers and gardeners for many years. It is known for its high phosphorus and calcium content, which promotes healthy root growth and beautiful flowers. Bone meal is also slow-release, making it easy to use and effective. In this article, we will explore how bone meal is made and how to use it in your garden.

Understanding Bone Meal

Bone meal is made from animal bones, typically from cattle but any bones can be used. The bones are cooked, boiled, or steamed and then finely ground. Bone meal is rich in nitrogen, calcium, and phosphorus, with phosphorus being especially important for plants. Plants in phosphorus-deficient soils can greatly benefit from the addition of bone meal.

DIY Bone Meal Production

Making your own bone meal is a straightforward process that involves a few key steps:

  1. Cleaning and Cooking: Start by cleaning the bones of any residual meat or cartilage. Boiling the bones for several hours is typically sufficient. Thicker bones, like those from cows, can be cooked in a pressure cooker or instant pot for a faster result. Cook the bones until they become brittle.

  2. Pulverizing and Dehydrating: Once cooked, the bones can be pulverized into smaller pieces and then dehydrated, or vice versa. You can use a blender to grind the bones into smaller fragments and spread them on a tray for dehydration. Alternatively, you can dehydrate the bone pieces first by placing them in a dehydrator for about 12 hours. After dehydration, use a mortar and pestle or a blender to grind the bones into a fine powder, similar to commercial bone meal.

  3. Final Grinding: If the bones are still chunky after dehydration, use a mortar and pestle or a blender to grind them into a fine powder. The goal is to achieve a consistency similar to commercial bone meal.

Application in Gardening

Using bone meal in your garden is simple. It can be mixed into compost, potting mixes, or used as a top dressing for garden beds. A general guideline is to use about one tablespoon of bone meal per gallon of soil. Bone meal is a gentle, slow-release fertilizer that will not burn plants, making it safe to use. For even better results, you can combine bone meal with other organic fertilizers like seaweed fertilizers and rock dust.

Making your own bone meal is not only cost-effective and easy but also a rewarding way to contribute to the health of your garden. While it is not a complete fertilizer, the high phosphorus content in bone meal is crucial for plant growth. This DIY approach to bone meal production adds a personal touch and promotes sustainability in your gardening practices. Give it a try and watch your garden thrive!
