Q&A: Are banana skins good for my plants?

Q. I’ve heard that banana skins are good for roses. Are they good for other plants too?
Mike

A. Banana skins are rich in phosphorus and potassium, which are both essential nutrients for healthy plant growth. Phosphorus aids seed germination and root development, while potassium promotes flower and fruit production. Young plants, in particular, benefit from phosphorus while their roots are developing, and root vegetables, such as carrots and turnips, guzzle phosphorus like it’s going out of fashion. Potassium is especially good for crops or trees that bear fruit, and is used in the process of building starches and sugars in fruit and veggies. Tomatoes, peppers, apples, pears, carrots and parsnips, etc, all love it. Cut your banana skins into small pieces and mix them with fresh soil or compost when planting a new flower, vegetable or shrub. Or lightly dig it into the soil around existing plants. Jane
