Hi, My rosella plants were growing beautifully, they are at waist high and have now developed spots on the leaves that turn into small holes (not mildew) They are trying to fruit but are struggling, still look great. Does anyone have any ideas on what this may be and a treatment? Regards John

Oakleigh State School in Brisbane has a school fair in September to raise money for the school. The PREP parents are given the task of making products for the Pantry Stall. We are trying to source Rosella as it is a uniquely Queensland taste that is sought after and will add great value to our pantry stall by stocking products made with this fruit. Any help or comments will be really appreciated -Delene

Hi Geoff - would love some of your recipes seeing you have been growing for years. I have tried twice and both times more like cordial than jam so I am doing something wrong. I can grow them no problems at all, but I want to make, jam, wine, cordial etc with them. By the way where do you buy that book?

I have grown rosellas first time in years, thought the plants were dying off but have been flowering and have already picked some for jam, cant remember if we used save the seeds and harvest again!!! Or do the plants continue on? Thanks

Presently have 3 rosella plants in have havesred twice, both after flowering, and now noticing that the plants are re-shooting buds again, now. Last year only havested once last year and pulled the plant out. But this year I am going to leave the bushes and see what happens.

We have 4 healthy looking Rosella bushes in our garden loaded with red calixes. Are these the ones we pick and make jam with? We thought it was the fruit following. Please advise by email as soon as possible. It would really be appreciated. Many thanks, Dieter and Jeannie.

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.
