Most gardeners will have seen these black plastic rooting balls that seem to be suddenly very popular. As shown in the above illustration, you peel away a bit of 'bark' on the plant you wish to propagate, fill the plastic ball with compost, then wrap it around the peeled area.
Roots are supposed to form within two months.
Being an old skinflint, I thought I'd try to save myself a Euro or two, and I used one of Billy's old Tennis balls to do the same job. A small amount of cutting and trimming, and the ball was ready. I'm trying to propagate our beautiful red Oleander.
Unfortunately I shall have to wait until early October to see if it has worked.
My fingers are crossed. I'll let you know!
