Question:
Does anyone out there know how to or if it is even possible to root a hibiscus from a large hibiscus that I have?

Answer:
Barbara,
Not only is it possible, but some varieties actually root quite easily.
- Start with woody cuttings that are about the size of a pencil in both length and diameter.
- Remove all but one or two of the leaves at the top - these leaves will help with the transpiration process as the roots develop.
- At the bottom of the cutting either scrape away some of the bark or simply make a small slanted cut through a leaf node (eye). This will make it easier for developing roots to emerge.
- When taking your cutting from the mother plant, it is a good idea to cut it at an angle above a leaf node that is facing out so that when new growth resumes, it does so in an outwardly direction.
- Hibiscus cuttings seem to root better when crowded together in a pot, so I encourage you to find a gallon - sized pot and try rooting several at one time. This will also increase your chances for success.
- Use a lightweight mixture of moist perlite and sand as your medium.
- Before inserting your cuttings into the pot, use a pencil to 'pre - drill" holes. Then dip the bottom of each cutting in some rooting hormone and insert them into the holes.
- Optimum temperatures for rooting are 60 - 70ºF. Hibiscus like a high degree of humidity so either mist the cuttings regularly or cover the pots with plastic bags. Just be sure not to bake them in the sun.
- Keep the pot of cuttings moist and in partial/filtered sun for about 6 - 8 weeks.
- Once the roots have developed, remove the cuttings carefully and repot in single pots.
Good luck!
