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.

I grew Rosellas for jam last year and though I am no expert, I harvested mine after they had flowered. I left some of mine too long and made more work for myself as they go hard after a while, so take them off when the flower petals have died off, not later into autumn.

I have 3 rosellas bushes about 2 metres tall and very helathy, they have been in about 5 months, but no flowers yet when should they flower and fruit?\

Coastal actually. Planting seeds before the ground has warmed up is frustrating. If you buy seeds, try planting early if you are keen. Some will do okay. Others will sit there and laugh at you before shrivelling. Simply plant another seed. In cool climates it is often pot luck, but they will eventually take off. They will survive and fruit well into autumn, especially in areas where there are no frosts. Pick them in flower daily and put them in the fridge until you have enough. Then boil them gently with a bit of sugar and progressively freeze them. At the end of the season thaw them out and make the jam. Patience is a virtue.

My rosellas have red flowers up stem and are healthy bushy plants. Will they get more flowers on the branches? The few up stems would not be worthwhile.
