We have 3 rosella bushes that are growing out of control. Do we need to prune them and when is best. How many bushes do you need for home use jam.

Why are my rosella plants wilting. There are no obvious signs of insect infestation. Could it be nematodes in the soil?

I am a transplanted Qld'er living in the central plateau of Madagascar, in Antananarivo. The temperatures are very much like Toowoomba, Qld. I brought Rosella seeds with me, planted the seedlings out the first week of Nov 08. They are growing vigorously and flowering nicely. Small fruit are starting to appear. Question: when should I expect the fruit crop to peak?

The NT Government has this on their Recipe Sheet for Rosella. Rosella Chutney Ingredients: ½ kg Rosella calyxes washed & dried thoroughly, ½ kg cooking apples, ½ kg onions, 2 large chillies (or capsicums), 2½ cups vinegar, ½ cup Worchestershire sauce, ½ cup raisins, 1 dessertspoon salt, 1 teaspoon black pepper, ½ kg sugar. Spice bag (1 dessertspoon whole allspice, 1 teaspoon cloves, 2 inch cinnamon stick, combine in clean muslin bag, remove before bottling). Method: Finely chop the rosella calyxes, apples, onions and chillies. Add remaining ingredients and boil together for 10 minutes. Add sugar and boil for ¾ -1 hour, stirring frequently. Bottle and seal in sterilised jars.

I plant in the first quarter nearest to 1st of Sept. I use Hibiscus fertilizer and have had great results. They are thirsty plants but don't like wet feet, and they are ferocious feeders.

The bush is quite large and looks healthy. I can see no evidence of pests but the immature fruit die off on the branch and harden. Can you please advise what I can do?

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.
