Hello VeryCherry:
It sounds like something was 'off' with your first attempts. Somehow your parameters need to be altered. If the cuttings are actually drying out, you might try increasing the humidity. Professional growers will use a misting bench for this, but you could try by spraying water from a spray bottle and/or covering the cutting pots with a clear plastic bag. Doing this correctly is a balancing act. If conditions become too stagnantly damp, you will get rotting instead of rooting. Perhaps try bagging the cuttings during the day, but letting them have more air flow at night. I would still use rooting hormone, and making sure the cuttings are properly trimmed and set, with one node above, and one node below the soil.
