Making Liquid Fertilizer from Banana Peels
Liquid fertilizer can be made quite easily from banana peels. There are two methods.
Making Liquid Fertilizer from Banana Peels Without Boiling
For this, you need a banana peel, a container, and a liter of water. The banana peel is chopped and placed in the jar. The whole thing is topped up with water and stored in a dark place for about a week. Occasionally, you can shake the jar. The finished fertilizer is mixed with water at a ratio of 1:3, and then you can water the plants with it.
Boiling Liquid Fertilizer from Banana Peels
For this, simply boil the chopped peel with ten times the amount of water—100 grams of banana peel in a liter of water. Then let the brew rest overnight, dilute it with water at a ratio of 1:5 the next morning, and strain the peels. Now the plants can be pampered with it.

Making Dry Fertilizer from Banana Peels – Here’s How
To make dry fertilizer from banana peels, you don’t need much:

The banana peel is best chopped as finely as possible with a knife or blender. The small pieces can then be worked directly into the plant soil. Whether fresh or dried—it doesn’t matter for the effect. If you want to store the peels for later, make sure they can dry thoroughly. Airtight storage is not recommended, as mold can easily form.
