Hi there. My gran used to root cuttings of her indoor geraniums just in a jar of water. I have had success doing this with the lemon-scented ones, (which Gran never tried) but cannot seem to get the pelargonium variety to take. I use just the top 2 or 3 leaves so they are only 3 or 4 inches in size. I change the water at least twice a week and they are kept on a sunny window ledge... what am I doing wrong?

I read online that it is possible to put a load of geraniums in a cardboard box to overwinter them, so I'm giving that a try too!
