Adding bone meal for your plants to your garden-care regimen could be beneficial. The organic fertilizer is rich in nutrients that promote healthy growth and can even improve soil composition. However, there are some drawbacks and limitations to using bone meal in your vegetable garden or yard, so do your research before picking up a bag.

Below, learn about the composition of this soil enhancer, its benefits and risks, and the best way to apply bone meal as a fertilizer.

As with any soil amendments, make sure to get a soil test before you add any fertilizers because excess amounts of a nutrient can be just as detrimental as nutrient deficiency.

Hey there, fellow garden enthusiasts! I’ve been using organic bone meal in my garden for years, and lemme tell you – it’s been a total game-changer for my plants. Today, I’m gonna share everything I’ve learned about this amazing organic fertilizer that’s been a gardening secret weapon since forever.

What the Heck is Organic Bone Meal Anyway?

Organic bone meal is exactly what it sounds like – ground-up animal bones (mostly from cows) that’s been steamed and pulverized into a fine powder or pellets. I know it sounds kinda gross, but trust me your plants will absolutely love it! It’s basically nature’s way of recycling nutrients back into the soil.

Typical NPK ratio you’ll find is 3-15-0 meaning

  • 3% Nitrogen
  • 15% Phosphorus
  • 0% Potassium

Plus, it’s packed with about 12% calcium – bonus nutrients for your garden!

Rich in Nutrients

Bone meal is particularly rich in calcium, which is an essential mineral for plant health that helps keep a plants cell walls strong and promotes sturdy growth.

Phosphorus is another key nutrient found in bone meal fertilizer. It plays a big role in photosynthesis as well as root, flower, and seed production. Phosphorus also aids in energy transfer within the plant and other vital functions, all of which lead to higher fruit and seed yield, healthy flowering and bloom growth, and increased pest and disease resistance.

This mineral really comes in handy when fertilizing tomatoes because the more a tomato plant flowers, the more abundant fruit it produces. In root vegetables such as carrots, phosphorous encourages root growth. Finally, bone meal fertilizer is a great source of nitrogen for plants. Nitrogen aids in protein development, enzyme production, and other important aspects of plant growth and health.

Slow-Release Fertilizer

Bone meal fertilizer breaks down slowly, making it the perfect long-term fertilizer. It only needs to be applied once per year or growing season (depending on the plants life cycle), since the bone meal will continue to feed your plants as it dissolves little by little. The natural decomposition process feeds the soil and increases its microbe level.
