Yates have a product called Natures Way Caterpillar Killer - Dipel. This is a natural bacteria spray that is absolutely harmless to everything except caterpillars. It works by disrupting the digestive system in the caterpillar which then dies.

I've started my seeds in a pot..can you tell me about how long until they sprout

From my research Rosella takes 8-10 days to germinate and, as it is sub-tropical, needs warm soil.

I have five bushes.Two are growing well and have produced fruit but not enough for jam.Does anyone know if picked fruit stores well in a fridge until there is enough? And does picking fruit encourage more fruit to grow?

Rosella is an annual plant. You could save some seed for next season. All the best.
