If hey get too wet they can die suddenly. I've just had a couple die off quickly.

My rosella plants don't seem to be fruiting is there something wrong or is it to early for them to fruit

I'm having having the same trouble. They would have normally flowered by now. The plants are looking healthy, just no flowers. Have you managed to find anything else out as to why? I'm also in Brisbane.

Do some research on the internet about it.

My rosella seems to be dying, do they die off and come back later or just die or is it just asleep. I live at Fitzgibbon Brisbane, thank you

It's an annual so it may have just died. Google and read about growing it.

My rosella bush leaves are being eaton by something I can't see anything on them but it is leaving small holes in them. What is a safe spray to use on the rosella bushes.

I use a neem oil spray on my bush. That's non harmful to the beneficial insects and only harms the things which eat the leaves.

Look up an organic spray.

I have rossella growing and in the past have been successfull however the last two times i have tried to grow these they get to a height of say 400mm and they start a dieback with a white sap like liquid coming out of the bottom of the plant eventually killing it.Any help would be much appreciated we live up in the mountains west of Sarina yes we get frosts however the last rossella plants die back in late summer.
