grafting pelargoniums

this now is all over the internet .I got in touch with the science program naked scientist told them about grafting pelargoniums they said what I thought ,never.but when i sent them the article from the university on there experiments and how easy it was to do grafting the split method.puting two different colours on one branch they now have got this in there archives,

now I have found a new way to graft ,yes graft not bud roses

have you ever heard of stenting ,in Sweden it means grafting and rooting a plant at the same time,they fierst choose the stock .airlayering  it with a good rooting powder,after three weeks.they graft the cutting with a split graft .cut it straight across .then run a clean knife down the center the scion is cut both sides and put in the v cut of the cutting ,tied up with raffier .they say that the split graft is better and faster then the t budding.
