Bundaberg is sub tropical climate zone, read up about climate zones in the blue tab at the top of the page. At the top of the page for Rosella you will see the months to plant, the big capital P. Just be careful with the current wet weather (14 inches for Feb so far) we are having. Maybe start them in some potting mix or a good draining soil combo. I live Coral Cove.

I have 11 big healthy rosella plants. No fruit or flowers are showing. Bit worried. Grown from seeds from last years plant as well as some seeds i bought off Ebay. Planted in trays Sept and transplanted into garden Oct 2019. Plants have grown quite big but are not flowering. Is it the extra heat this year? Will they still flower?

Things are looking up. 19/02/2020. Buds are appearing on the bushes. First flower out this morning. Awesome

Hi Clive, my Rossellas are pretty much at the same stage and I'm not expecting any flowering until the early early dry season perhaps late April.

It does say 21-25 weeks from sowing. Middle of this month would be about 21 weeks. Hope they flower soon.

You may have over fertilised them. Usually when plants are really big and strong and not flowering etc they have had too much fertiliser especially N.

Do you have Rosella seeds or plants

This website doesn't sell any seeds etc. Try a nursery, Bunnings or even facebook- market place. A person is selling seedlings in the Bundaberg area now on marketplace.

surely to goodness somebody must know the answer as to why rosella plants wilt all of a sudden,It is nice to see all the qustions mentioning the various stages of wilting all of a sudden.this is all very well and good to know that I am not the only one this is happening to.Where are all the answers.Surely their must be some experts with the solution to this problem.Or don't they want us to know for some unknown reason? Surely some of the commercial growers must know.or do they have access to the cure that the home gardener is banned from using such as fruit fly prevention is very frustrating not to know the reason why this is happening.i am trying Yates Root Rot prevention at the I on the right track?

There are no experts on this website I'm sorry to say. I'm just a home gardener trying to help genuine people. I grew parsley a few years ago and about this time of year it just died in the space of a week, very healthy plant to brown in a few days. When I have a problem I go looking on the internet. Ring up your state government agricultural department. Agricultural supply companies.

Full grown rosella bushes looking very healthy, and then suddenly wilting and dying for no visable reason. They were just starting to flower and some very starting to set fruit. Any help would be appreciated.
