My new dragon fruit cuttings I got around a week ago have not been doing the best. One of them came with roots but the other two did not. The one with roots has been flourishing fine in the soil and the two that didn't have begun shriveling up in their soil (currently growing in pots) and I don't know what to do. They're in half shade and I have only been watering them when I saw the soil was dry. My soil is half and half succulent mix and gardening soil.
