The reason they are limp is lack of hydration and photosynthesis. My cuttings often wilt for a day or 2, when they do, heres what I do. Support them! Make little stakes to support them, especially since there is a lot of leaf material there. If you get the leaves fanned out, this allows for photosynthesis, which will help root development. Make sure you spray the tops of the leves and not the bottom with whatever you are spraying them with. Again, this helps photosynthesis and transpiration which will help the flow of water through their system. They are from a good looking healthy mom and will recover given a little time. Steak them, spray them, leave them under 24/7 lighting and in a week you should have some roots. JMO W
