How can i root tropical hibiscus?
Take cuttings (not hard wood) remove lower leaves the hump where the leaves are is called a node. That is where new roots will grow from. Get some vermiculite, per-lite or sharp sand. I prefer them in order given. Wet the medium (vermiculite) evenly and place cuttings in it. Try to keep your fingers and contaminates out of the mix. It can be done in trays or pots or in a old aquarium. Drainage is good or just keep the mix moist not soggy. Place in warm bright spot. A green house of fruit jar or plastic tent could be used if wilting starts. Fewer leaves are better than a lot. Cuttings should be about 6. Root stimulator or hormone could be used in mix to expedite faster rooting.
I have rooted hibiscus before. Heres how I did it: first I cut the new growth. If you know anything about plants you should be able to tell. Its usually greener than the more brown previous seasons growth. Then I cut a piece that had no obvious flower blooms on it. Then I wet the end of the piece I cut and dipped it in Rootone. This can be bought a most garden centers or even a major department stores. Then I but the dipped end into some regular potting mix and place in a partial sunny spot or even in a sunny window indoors. then keep moist. I usually wait to plant it untill the following year. That way the roots have a chance to get established. Good luck. (also wash hands very well after using the rooting hormone for safety) Oh and only leave two leaves when you root. Thats how I did it.
Tropical Hibiscus is usually very easy to root. Make eight inch cuttings of the semi hardwood. Not the branch tips. Strip all but the top two leaves and put the bottom ends in a glass jar with water up about a third of their length. If you have some rooting hormone use it but if not, no problem. Keep them in a semi-sunny location and probably the most important thing is to change the water every couple of days. Otherwise it will sour and rot the cuttings.
