Gardeners who want bigger flowers and juicier crop harvests this year should start saving their banana peels now to give their gardens a natural nutrient boost. Spring is just a few weeks away, so now is the right time to start preparing fertiliser as March is when plants need plenty of nutrients, as the soil is often depleted after winter.
Holly Noakes, a gardener who goes by Sustainable Holly online, has shared that banana peels contain potassium, which is the nutrient needed to enhance flower and fruit growth, which will help plants grow as lush as possible. She said: “Banana peels have potassium, which is an essential nutrient for promoting more flowers and fruit on plants. Prioritise your dried banana peel fertiliser on your flowering plants such as Pumpkin, squash, capsicum, and fruit trees. Promoting flowers will offer more chances of fruit!”
Banana peels are best known for their potassium, but they also provide phosphorus, which promotes stronger roots to help plants take up more water and resist wilting.
They also contain magnesium, which helps the leaves grow so they absorb more energy, and can even enhance the sweetness of fruit.
Hydrangeas and roses especially love banana peels, as they boost overall health and deepen flower pigments, resulting in more vibrant blooms.
Tomatoes, strawberries, and peppers also thrive on potassium, so feeding them banana peels when they are first planted helps ensure bigger, juicier produce.
However, bananas are usually good for any part of your garden, as they are a slow-release fertiliser that can make the soil richer and healthier without needing any other products
How do you turn banana peels into a fertiliser?
If you want to use banana peels in your garden, you cannot just throw them on the ground, as that will attract pests like ants, flies, and even rats.
Instead, you need to dry the banana peels first so they do not rot, which helps concentrate the nutrients and feeds the plants for a longer period of time.
All you need to do is place any leftover banana peels on a tray and then leave them somewhere warm, like next to a windowsill.
Let them sit in the sun for around one day until the peels turn black and crispy. Then, all you need to do is chop them up into small pieces and place them in a jar.
Once they feel crumbly, you can crush them into a powder and scatter them around your garden. You can also add two tablespoons to a watering can to pour on plants.
