‘Vital for healthy growth!’ How to use banana peel to ‘promote flowering’ in your roses

While you can’t get away with fertilising rose plants with only bananas, adding leftover peels to the soil around your rose bushes provides a boost of potassium essential for healthy, beautiful blooms.

While banana peel contains a variety of nutrients, there is one that it misses out on. Angela said: “Bananas don’t contain nitrogen so are not as useful as a fertiliser for green leafy plants but the calcium they contain helps the plant be more efficient at extracting nitrogen from the soil.”

However, banana peel fertiliser is perfect for plants with low-nitrogen requirements such as tomatoes, peppers, cucumbers, and even radishes.

The gardening pro also shared how banana peel makes for an “effective” liquid fertiliser.
