i started to root 4 cuttings of hibiscus a month ago.....they look nice and healthy......with new leaves......in order not to reach crowdiness in the plant pot i wanted to transfer them into a bigger container......to my surprise they had no roots......they just had dark ends .....so i transplanted them......but i think i need to go back to the early stages of keeping them in artificial humidity and maybe give them some more rooting powder?
