To propagate geraniums from cuttings, first select containers three to four inches deep and fill them with moist (not overly wet) planting medium. Satisfactory rooting media include coarse sand, perlite, vermiculite or a mixture of these. Sterile commercial mixes are also available. Cut off shoot tips three to five inches in length and remove the leaves on the lower part of the stem. The use of a rooting hormone is recommended to stimulate the rooting process.
