Banana Peel Water: The Zero-Waste Fertiliser Your Plants Will Love

Wednesday, October 15, 2025

Bananas aren’t just a healthy snack for us – their skins are a hidden treasure for your plants too. Instead of throwing them away, you can use banana peels to create a simple, zero-waste fertiliser that’s packed with nutrients. This guide will show you exactly how to make banana peel water, why it works, and how to get the most out of every peel.

🌱 Why Use Banana Peels for Plants?

Banana skins are rich in potassium, phosphorus, calcium, and magnesium – nutrients that support:

Stronger roots
Healthier leaves
More flowers and fruit
Improved overall growth

Best of all, they’re free, natural, and a perfect way to reduce food waste.

🍌 How to Make Banana Peel Water (Step-by-Step)

Step 1: Soak the skins

Place fresh banana peels in a jug or jar.
Cover with water and leave to soak for 24–48 hours.

Step 2: Use the enriched water

Pour the banana peel water directly onto your houseplants or garden soil.
The nutrients released into the water help feed your plants naturally.

Step 3: Refill a few times

You can top up the jug with fresh water and reuse the same skins a couple of times.

Step 4: Dehydrate and crumble

Once you’ve finished making banana water, don’t throw the skins away.
Dehydrate them in an oven, dehydrator, or warm sunny spot.
Crumble or grind the dried peels and add them straight into your plant pots for a slow-release fertiliser.

🌼 FAQs About Banana Peel Fertiliser

Q: Can I put whole banana peels straight into soil?
Yes, but it’s better to chop or dehydrate them first. Whole peels take longer to break down.

Q: Is banana peel water safe for all plants?
Most plants love it, but go easy with succulents and cacti as they don’t need as much feeding.

Q: How often should I use banana water?
Once every couple of weeks is plenty for houseplants. For garden plants, weekly use during growing season works well.

🌍 Final Thoughts

Banana peel water is a quick, natural, and zero-waste way to keep your plants healthy. With just a jug of water and some peels, you can create a free fertiliser that benefits your plants and the planet.

So next time you enjoy a banana, remember – the peel is plant food in disguise! 🌿✨
