At a total loss!!
I'm at a total loss! I've been trying to propagate dahlias using tip cuttings and my success rate is less than 20%. I've tried everything that I can think of and what drives me crazy is that people say its so easy. I've tried a peatmoss/perlite/compost mix and oasis cubes. I've tried high humidity and low humidity; with a dome and without a dome. I've disinfected my tools, trays and anything else that might come into contact with the cuttings...including my hands. I've tried a rooting hormone with and without a fungicide. I'm trying to root them indoors under artificial light and maintain a temperature of 68 - 70 degrees. I really don't know what else to try. Does anyone have suggestions? I keep looking for new information that I might have missed. Any help would be greatly appreciated!! Thanks, Henry
