She said: "Believe it or not, banana peels can be a terrific organic fertiliser to help your orchids bloom! Who would have thought that something we consider garbage has such great value for our plants?”

She continued: “When I first heard this idea, I was sceptical too. But after trying it myself, I’m a believer. My orchids used to bloom so sporadically, maybe once or twice a year if I was lucky. But ever since switching to banana peels as a fertilizer, they bloom like clockwork several times a year.”

This is because banana peels are extremely rich in potassium. Potassium is one of the core nutrients that plants, including orchids, need to grow healthily. It’s particularly helpful as we we enter the summer season, as it also helps plants retain water. This in turn makes them far more resistant to drought.

Aside from potassium, the peel contains a healthy dose of calcium and magnesium. These minerals help to promote root growth and assist with photosynthesis.

Banana peel also rich in sulphur, which helps plants develop strong roots and prevent pest infestations. This includes attacks from aphids, small sap-sucking insects that can stunt plant growth, damage leaves and even spread diseases like turnips yellows virus.

When placing the banana skins in your garden, ensure that you put them in a single layer on the soil. Also take care to avoid touching the plant roots.
