I planted my rosellas in August '20 then potted up into half wicking pots and half hugelkultur pots, some in small plastic garbage bins. I have 10 plants. Of these, 4 started as seedlings from Bunnings, the rest were seeds I'd saved from previous years. Only 1 of these plants is flowering and fruiting. All look very healthy. I thought to give the non flowering ones some potash to help them flower. Will this encourage them?

A bit of potash shouldn't hurt, but I've found that mine don't start flowering until the days start getting shorter, no matter what I do! It should just be a matter of time for the rest of yours to start. Your precocious plant might be getting just a tiny bit less sun than the others due to placement in the garden. The end of my row that's closest to the house always starts flowering first, because it gets an hour less sun than the other end of the row.

when should you pick your rosella fruit?

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 recently met a gent who told me that rosellas make a beautiful chutney. Would there be a grower who could share a recipe? With thanks,in anticipation,Lynne

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.

After a lovely harverst, I cut down the plant and a few of them look like as if they are dying. How do I look after them after flowering and seeding as this is my first year. Comment for jam making, you do not have to boil the seedpods, there is enough pectin in the fleshy part to set and it is a cleaner taste. I have been making jam for years.
