People who frequently grow flowers are certainly familiar with various methods of making their own fertilizers. For example, bananas contain a large amount of potassium, making them an excellent fertilizer material. So, can a whole banana be used as fertilizer ?
Can a whole banana be used as fertilizer?
A whole rotten banana can be used as fertilizer. Although the banana is rotten, its fertilizing effect remains unchanged. It contains rich potassium, and for flower varieties such as roses, it is more effective than ordinary chemical fertilizers.

What are some methods for using bananas as fertilizer?
1. Using banana pulp as fertilizer
Soak the banana pulp in a bottle with water for about a week to allow it to ferment fully. Make sure the lid isn't completely tight; leave it slightly loose to prevent gas buildup inside the bottle.
After a week, you can use the fermented banana water to water the flowers and plants.
II. Using banana peels as fertilizer
1. Use scissors to cut the banana peel into small pieces for easier processing.
2. Find a large trash can if possible. First, put about 10 cm of potting soil at the bottom of the trash can. Put an appropriate amount of banana peel fragments into the soil, then cover it with a layer of soil, then add another layer of banana peel fragments, until it is full, and then seal it with soil.
3. The composted humus can be used directly for planting flowers or as fertilizer.

III. Other uses
After drying the banana peels, grind them into powder. You can mix the powder directly into the potting soil or mix it with water and water the plants. Alternatively, you can decompose the banana peels by sowing them. Bury the peels deep in the ground before planting the seeds. As the seeds germinate, the peels will gradually decompose, becoming nutrients for the plants.
