how do you get the green seed out of the calyx without cutting the calyx? I want to do some in syrup but can't seem to get the "flower" whole

To remove the seed leaving a full fruit you should take a thin slice from the base of the fruit and push the seed out with a chopstick from the thick end to the pointy end. The seed will gently part the petals and pop through. Easy as! I can seed a bowl of fruit in less than five minutes.

It's fussy work for you and very tedious but if you'd like to try this method. My wife, Janine and I were shown the following: Get the stem of a broken umbrella; push that up through the petals; the seed pod (calyx) will pop through.

When I was a child my father made a "Rosella de-leafer" by attaching an empty bullet casing to a handle - it worked well & I still have it. Maybe you could try an apple corer?

My dad did the same for my mum out of a piece of metal gal tube or stainless tube (I think it was out of a bicycle pump??) He put a bit of tube over it so it wasn't sharp for a handle, works a treat. I still have the one that he made for me as well.

We found that around September was about the best time.

Just had my wilting rosella plants diagnosed by the nursery where I bought them. They said it was typical of too much rain/water - so grow them high and don't mulch during heavy rainy periods like - A nematode or two on roots but not enough to kill a plant starting to flower like mine - suggested to water with a weak solution of condies crystals and interplant with marigolds to discourage nematodes. Bought 4 new plants to try again now that the big wet seems gone.

Trying to find a cure for my rosella plants wilting - we have had very very wet and humid weather, so put it down to that and have been trimming back the wilted leaves and cultivating around the roots to aerate them, seems one plant has new shoots. Or could it be nematodes - don't understand much about them - then again the scrub-turkey and quail scratching around them could have exposed the roots ??? Any advice welcome. Cannot seem to find anything helpful in the myriad of books and web-sites I have been scouring over the last week.

I live at Kilcoy QLD (Somerset Council area) & I always plant my Rosella seeds in seed trays 2nd week in August & raise under black plastic.. They germinate pretty quickly this way which allows me to have them high enough to transplant into raised beds before end of September. This way I can usually start harvesting the rosella pods by end of Dec. They keep bearing until the first hint of winter (temperature drop or cool winds) they then turn up their toes & I pull them out..I rest my beds & grow a green manure using cheap canary seed which I trim back with whipper snipper to break down in to the soil.
