says"
The use of a rooting hormone increases rooting uniformity. Apply 1200 - 1500 ppm IBA (indole-3-butyric acid) in powder or liquid form to the bottom one-eighth to one-fourth inch of cuttings before sticking. An alternate method is to spray cuttings after stick with 200 ppm IBA. If spraying IBA, stick cuttings, water in, mist, and spray after dark or in early morning and resume mist after cuttings begin to wilt.
