Did you know that you can make a really easy, all-purpose garden fertiliser from your banana skins?
Just grab a container and soak two or three skins in around 600ml of water for a few days (or you can put about a litre of water in a bucket and just add your banana skins daily).
The minerals will leach into the water and then you can pour this liquid directly onto your plants - no need to dilute.
To complete the cycle, give the soaked peels to your worms or add it to your compost. Easy!
