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.

I have several rosella plants growing and now starting to flower with a yellow flower and a red base. I am not sure what the fruit looks like, does the fuit form after the flowering and when should it be picked?

HI! I am a bit confused about when to pick the fruit off my Rosella bush, to make jam, at present I have the red pods and now some of them are getting flowers do I pick them before they flower or after. Thankyou

Rosellas are best picked after they flower and when the red fruit/pods are large (around 2-3cms in length) but not too old. If they snap off the bush, that indicates that they are not too old and stringy - though if you do have to cut them off, they can still be successfully used for jam and other recipes.
