Why Make Dried Banana Peel Powder Fertilizer at Home?

Banana peels are rich in potassium, which is crucial for any plant’s healthy growth. They also contain 42% potassium, 3.25 % phosphorous, and some other micronutrients.

In every gram of fresh banana skin, you can find 19.2 mg calcium, 76.2 manganese, and 24.3 mg sodium. Additionally, it contains a small amount of sulfur and magnesium essential in chlorophyll production. 

Using banana peels can help in the following ways:

  • Strengthens the plant’s immune system
  • Prevents wilting
  • Improves the quality of fruits
  • Nourishes the roots
  • Helps in the flowering process
  • Give plants energy to fight diseases
  • It makes plants more drought resistant
  • Resistance against pests

Banana peels are also unique because they do not contain nitrogen, which makes them ideal for plants like peppers, cucumbers, radishes, tomatoes, rhododendrons, azaleas, gardenias, blueberries, roses, hibiscus, fruit trees, spinach, lettuce, and Swiss chard and many more.
