prafullashahi, Are the new owners willing to allow you to take the whole plant? Can you dig it up and move it?
If not that is why I recommended the side shoots off the main stalk. They would root the best in my opinion.
I don't use the rooting hormone. I just cut and put directly into the soil. When talking about soil, I do not use
any of the ones with miracle-gro in it. An all around organic potting soil should work best. You could use the
main stalk, but if you do strip it but leave the top leaves. Do try to use also the side shoots and try to root them.
I only recommend doing tip cuttings if you have a greenhouse with proper lights.
I keep a 5 gallon pot of dirt by my back door all year around and it I come across a broken
branch I will strip and recut to just put it into the pot. These will stay there for a year to make
sure they are well rooted. We have several varieties of Perennial Hibiscus which if a great
fall color in the yard. I also have some special ones growing in the greenhouse under lights.
