How Banana Peels Help Cucumber Plants?

Banana peels make for an ideal gardening ingredient, mainly because of the nutrient profile they contain. They are composed of 42 percent of potassium. In fact, banana peels have very high sources of organic potassium.

Potassium helps plants to transport nutrients and water between cells. Potassium strengthens plant stems and also fights diseases. It is very important to create flowers, and even make fruit (and berries!) It tastes better.

Potassium will make your plants resistant to drought. This is important because without enough potassium content in plants, their growth reduces and becomes very poor. Banana peels even grow the protein in your plants.

The skin of bananas or leaves is rich in nutrients, making it an excellent source of natural fertilizer for your yard and garden. They are a good fertilizer because of what they do not contain. They do not contain any nitrogen at all.

Potassium-rich banana leaves are best for plants such as tomatoes, peppers or flowers. The banana leaves also contain calcium, which prevents the decaying of flowers from tomatoes. (Source for NPK ratio)

Manganese in banana leaves facilitates photosynthesis, while sodium in banana leaves facilitates the flow of water between cells. Recently, traces of magnesium and sulfur are found in peels that help elevate the chlorophyll.
