Using bone meal regularly can significantly improve the chances of healthy and consistent flowering, especially in plants that are struggling to bloom.
Fertilizer #2: Vegetable Charcoal – A Soil Enhancer Rich in Nutrients

The second ingredient is vegetable charcoal—but it’s very important to use the correct type. This should be raw vegetable charcoal, not the type used in barbecue grills, which usually contains grease, chemicals, and salt. These substances are harmful to plants.

Vegetable charcoal, in its pure form, is a natural source of:

Carbon – Improves soil structure and promotes beneficial microbial life
Magnesium and Boron – Essential for chlorophyll production and nutrient absorption
Organic Matter – Helps retain moisture and improve soil aeration

Together, these nutrients work to enhance plant development, especially when paired with the phosphorus-rich bone meal.
