Making fertilizer from banana peel: DIY instructions and other ideas for uses in the garden

Garden and indoor plants need water, fresh air and nutrients to grow magnificently. It is therefore advisable to fertilize the flowers and shrubs regularly, especially in spring and summer. There are many variants to choose from in stores. A special fertilizer is offered for almost every plant family. But it doesn’t have to be that complicated: in most cases you can do without special fertilizers and even make the fertilizer yourself. In this way you can reduce the negative effects on the garden soil and biodiversity and at the same time enjoy high yields and flowers. In today’s article we explain how you can make fertilizer from banana peel and tell you what other uses organic banana peel can have in the garden at home.

Making fertilizer from banana peel: Only use bananas from organic plantations

Buy organic bananas and process them into fertilizer

The banana is one of the most popular fruits among Germans. A family of four eats an average of around 400 bananas a year, which is around 14.5 kg per person. About a fifth of it – around 3 kilograms of banana peel ends up in the organic waste. It’s a shame, actually, because the peels of the exotic fruits are rich in nutrients such as potassium, magnesium and calcium. That makes them the perfect ingredients for a liquid fertilizer. You can make fertilizer from banana peels only, or you can combine them with other materials like coffee or eggshells. Above all, it is important that you only use bananas from organic farming. Conventionally produced bananas from the supermarket can contain pesticide residues. The plantations are treated with anti-mold agents before harvest so that the fruit does not rot on the long way to the supermarket. In addition, the bananas are very susceptible to certain types of mushrooms and are therefore watered with special mushroom agents during the ripening period. All of these harmful chemicals build up in the shell. If you use it to make fertilizer, the pesticides get into the soil and garden plants and can damage them. So if you want to make fertilizer from banana peel, you should use organic products.
