Homemade banana fertilizer | DIY the easiest recipe

  • DIY, Eco

Hey guys! Today I have something completely new for you: a recipe for homemade banana fertilizer, the first recipe in a new series of eco-gardening tips.

It is definitely the cheapest, the fastest and the easiest in the world to make specific for indoor plants and others, which will certainly work for everyone. To make it, you only need a fruit peel and a container, and it’s ridiculously easy to make, so it’s definitely worth a try. In addition, there is no fear of overdoing when fertilizing with such natural eco-agents – unlike in the case of purchased, expensive and chemical-laden typical fertilizers. Therefore, I heartily recommend this long-known invention to everyone – my flowers grow on it (almost) like yeast.

Banana fertilizer is the cheapest way to feed your plants with phosphorus and potassium, especially beneficial to garden flowering plants, but it also has a great effect on indoor plants and can even improve the flavor of vegetables, especially tomatoes, at times.
Banana fertilizer can also be used as a remedy for plants attacked by aphids.
I invite you to my (tried and used for years) recipe for home and simple plant fertilization.

Recipe for homemade banana fertilizer


  • fresh banana peel
  • jar or other glass container
  • boiled, cooled water

Manufacturing method:

  • First, a necessary step: we buy and eat bananas 😋 They are not only delicious, but also very filling and healthy. They have many vitamins and minerals, including a lot of potassium and phosphorus. These elements will be useful to our muscles and home flowers. Fortunately, they are also contained in the peel of the fruit.
  • Then we collect the skins, after ourselves or other household members. However, it is best not to keep them for too long, they are best for us fresh.

  • Then we cut the skins into smaller pieces. Pour them in a jar with boiled water, just enough to cover them.
  • We put the jar in half the sun, shake it from time to time. It is enough once a day, or even once every few days.
  • After a week-two, the fertilizer should be ready. You have to check it from time to time – I use mine when the water in the jar becomes a little cloudy, and the skins show darkening.
  • Drain the skins and throw them away (you can still throw them on the compost) and dilute the cloudy water.
  • It’s best to use banana fertilizer right away, or maybe a day or two in the refrigerator.

How to use homemade banana fertilizer?

We dilute this ready- made banana fertilizer with a little stagnant water and we can easily pour it directly into the flower pots. The potassium and phosphorus contained in this cloudy liquid is exceptionally well absorbed by the roots of our home (and not only) plants.
The fertilizer does not smell too bothersome and the flies do not fly down to it, especially when we make small portions – peel – two of the fruit into a small jar and use it to water home flowers.

Of course, there are other ways to make banana fertilizer, but this one is the fastest and least troublesome in my opinion – anyone can make it in a small jar and make extra money as needed.
You can also collect the skins in a bucket, add and add water and then water the whole garden with this dissolved pseudo-compost. The greengrocer will surely benefit from it. If you eat so many bananas of course …
