I love gardening. But I am not really too good at it. So when the trailing rose that I bought in full flower didn't get any new blooms after the ones that came with it died, I rang my father-in-law, who grows beautiful roses.
He suggested trimming it back and putting.... a banana peel in the pot. Apparently roses like potassium, to flower well. And a great source of potassium is decomposing banana peels! I am pleased to report that my rose soon produced another flush of buds.
So, my WFMW tips are:
1. Put banana skins around your roses (or bury them near the roots, if you don't like the sight / smell!); and
2. Give even strange-sounding advice a go, if it comes from someone who has demonstrated expertise in the area!
