Cutting back my Hibiscus
I have hibiscus. It's about 6-7 years old and is around 7 foot tall. I need to cut it back and transplant it. How far back can I cut it and when is the best time to do it? I have 5 hibiscus plants and they all have yellow leaves, some normal green ones and the leaves are small. What can I do to help them? Thanks. Jenny Ogilvie in west Footscray Melbourne Victoria

You can generally prune back the plant by 1/3.
Yellowing leaves can be a few different reasons. May indicate a watering issue, to much or to little.
Pests and disease also can cause yellowing leaves, as well as just normal leaf aging.
Neem Oil is a good treatment as this works as both an insecticide and fungicide.
