New hibiscus doesn’t grow
I got 3 Hibiscus plugs about 2 months ago and they never grew anything. I repotted them and see hair like growth on them. Is this the beginning of growth?
Did the plugs not have growth when you got them? I think they should have. After two months you should have had, depending on the variety, from several inches to over a foot of growth. Hair-like growth sounds like mold - plant growth is going to be green. Here are a couple of articles on growing hibiscus: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/how-to-care-for-hibiscus-plants.htm
Remember that growing hibiscus indoors, even just starting them, requires a minimum of several hours sunlight. And keep the soil damp, not wet. If there is water there when squeeze soil between your fingers, don't put more water on it.
