As a new plant mom I didn’t realize the importance of fertilizer, and once I did realize how important it was, I hated the price tag. We always try to recycle, reuse, and compost whatever we can. When I saw you could use banana peels for plant fertilizer I had to give it a try. It was the easiest thing to do and it gives your plants great nutrition- all for free! Plus you probably have everything you need already.

Best mason jars!

Make your fertilizer with these mason jars that Amazon reviewers swear by!

What you’ll need:

banana peel


Glass jar (we used a mason jar)

Put your banana peel in your jar and fill it up with water. We used plan tap water.

After a few hours the water will start to discolor. We let ours sit for about 24 hours before using it.

After a day had passed, we watered all our plants with it!

Again- it can’t get easier?!

Once we were done, we composted the banana peel and just continued to repeat the process! We’ve been doing this for some time now and our plants are loving it, and if you’ve been here for a while, you know I love a free and easy project.

Try it out and let me know what you think!

    Do you put the lid on the jar or just let the jar sit uncovered?

    I also use onion peels (discourage pest), potato peels, apple peels, and so many other vegetables are beneficial as a fertilizer.

    I put in a plastic jug 1 gallon size or larger. I put peels banana or shredded carrot or both let soak in closed container for about two weeks then pour on your plants like you normally water. It's not going to smell good but plants love this about once a month. I use on my outside crown of thorns cactus loves it.
