Why This Fertilizer Works So Well

• Banana peels supply potassium → essential for flowering and fruit development.
• Eggshells provide calcium → prevents blossom-end rot and strengthens cell walls.
• Coffee grounds add nitrogen and gently acidify the soil (citrus trees prefer slightly acidic conditions).

This balanced combination supports strong roots, healthy leaves, abundant flowers, and juicy fruits.
