The info here says plant Oct to Dec and it takes 21-25 weeks - so you have planted out of season maybe. Maybe you used too much fertiliser. Plants will go to seed or fruit when the nutrient has been used up or when the season is right. Most vegies are seasonal to each climate zone.

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

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.

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.
