My mum has rosella bushes and they have been fully loaded with fruit and before the fruit is ready the bushes are just dying. This is also happening to her neighbour . All her vegetables and roses and gerbera are not having a problem. Any suggestions??

Ant don't like turmeric. You can stop the ant by making a circle of turmeric powder at the base of the plant where ants won't cross it. Or sprinkle turmeric powder on the affected area on the plant.

Contrary to the culinary advice, use the whole 'fruit' for jam making. Separate the lovely red calyx from the green seed pod. Cover the seed pods with water and boil for 15-20 mins then strain the pods out and use the liquid to start cooking the calyxes (you will probably need to add more water). The pods contain the fruit's pectin supply so the jam will set much better.
