Bone Meal is used as an organic fertilizer or amendment and is a great source of Phosphorus to ensure the plants flowers grow bigger and more plentiful. Most Bone Meal has a NPK of 3-15-0 and can be used to increase the amount of Phosphorus in your grow medium. Phosphorus is essential for plants to start their flowering process and will help you flowering plants to grow bigger and more plentiful flowers.
It is important to have your soil tested before you add Bone Meal as it's efficacy will drop significantly if your grow medium's pH is above 7. If you find you have a grow medium higher than 7 rather correct your pH first and then add Bone Meal. You can then add about 4.5kg's of Bone Meal per 9 metre squared area. It will release Phosphorus into the medium for up to 4 months after being applied.
It can also be used to balance out high Nitrogen, organic amendments for example manure tends to provide a great source of Nitrogen but is normally lacking in Phosphorus so introducing Bone Meal will help to create a perfect balance.
