Using the skin of a banana is cheap, easy, and convenient. I love making homemade fertilizer from things that would otherwise be thrown in a bin. The idea of getting a second use makes it all the more rewarding.
Banana peels are rich in potassium and magnesium; using the skins is an excellent way of adding these nutrients to your plants.

What does potassium do for plants?
It helps plants to manage periods of dryness as it regulates the uptake of water;
Necessary for activating plant enzymes;
Regulates CO2;
It is needed to make Adenosine Triphosphate (ATP), which is necessary for photosynthesis and the activation of chemical processes in the plant.
Potassium is the most essential nutrient for a plant, second only to nitrogen.
2. What does potassium deficiency look like in plants?
The leaves are turning yellow. Please take a look at the pictures.
3. What does magnesium do for plants?
Magnesium helps plants make chlorophyll, which is responsible for green leaves.
Chlorophyll is needed for photosynthesis, allowing plants to get sun energy.
4. What does a magnesium deficiency look like in plants?
If your plants are magnesium deficient, they will be yellow on the edge of the leaves. Have a look at the examples below:
5. How to use banana skins to prevent deficiencies
Take a bottled, distilled, or rainwater glass and soak the banana skin overnight.
The banana skin will turn slightly darker; the water will be slightly brown.
Use this water directly on your plants.
