I have 30 plants that I started in October. I have just harvested about 50 rosellas and made 5 jars of jam. My soil is not that great but since giving the plants a good feed they have perked up. They do not like wet feet. I have lost 1 plant due to my accidentally disturbing its roots. I have thousands of little holes in the leaves which I think are grasshopper nibblings. I have noticed some grubs in the last 2 days and have 1to identify. It has yellow stripes longways and black dots side by side across its length with white hairs. Does anyone know what they are?

Same here - in fact we have lost a few really healthy Rosella bushes - think it was the excessive rain - the trunk of the plants went black

Hi there, we have just been initiated into the art of growing the wonderful Rosella plant as my hubby was presented with one for Christmas. We have limited space but would like to know what postion in sun or shade or semi shade it favours. we don't want to kill it. it is about 3 ft tall in a pot and its little leaves are curling up already. Any hints much appreciated.

Eden Seeds have Rosella seeds available at present and you can order online. I grew them in my hydroponics last year and made my first rosella jam since I left the tropics. You need to get them started as soon as possible to allow enough time to fruit before it gets cool.

hello i would like to hear about your hydrponics set-up. we are hoping to get students growing rosellas in individual hydrponic pots made from recycled plastic bottles, but not sure how to start. did you raise your seeds in soil first, then transplant into the hydroponics? thanks

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.
