Due to the nitrogen present in blood meal, plants experience robust vegetative growth. As phosphorus is present in bone meals, this nutrient is helpful in proper flowering.

Can You use Bone Meal and Blood Meal Together?

Bone meal and blood meal are both nutrient-rich soil additives that can be used together. A blood meal is dried and powdered animal blood that boosts nitrogen levels in the soil.

Bone meal is made out of ground animal bones that raise calcium and phosphorus levels in the soil. Small levels of magnesium, iron, zinc and other trace elements are also present in bonemeal. These micronutrients are also necessary for smooth plant growth.

How to Mix Bone & Blood Meal for Potting Soil?
