Hib cuttings, need help with please--
I have several cuttings of a purple hibiscus, Midnight Blue, that I am rooting. Doing well except for a yellowing of the leaves. In checking for roots I found they didn't have many yet so I'm afraid to use regular fertilizer. Any ideas on what I can use that won't hurt them? This is my first attempt at rooting cuttings so could really use some help!
