I googled for how to start pelargoniums from cuttings. One source recommended letting the cuttings dry and callous over for a day to prevent rot, so I did that. I took the cuttings and threw them in the garage for a day. The next day they were pretty wilted and the cuts were calloused. I stuck them in barely moist (not wet) potting mix. Didn't bother with rooting hormone. After potting I misted them, put in a flat and covered with a humidity dome. They perked up and rooted pretty fast- within a week or two. I kept them under my lights and they bloomed most of the winter. Very easy.
