I have been trying to take semi-hardwood cuttings of rose of Sharon (Hibiscus Syracus). I have been attempting to follow the procedure in the reference manual of wood plant propagation (M. A. Dirr, C. W. Heuser) This is the following procedure: Take current years growth and remove leaves from about 2 inches of the stem. Dip for approximately 15 seconds in diluted Dip and Grow then place in propagation bed under plastic. Bed is in light shade with no direct sunlight. Bedding mixture is 50:50 Peat and vermiculite. The problem I am having is the leaves are turning yellow and looking generally quite poor. I looked over the "quick dip method again and noticed a drying step after the 15 second dip in the rooting solution. Has anyone ever rooted this way or does anyone have an alternate method of vegetative propagation for this plant. Any help would be appreciated Dave M Zone 6A (SE PA)
