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.

are Rosella plants able to be kept growing for a second season, our crop this year of four plants are around four foot high and seem extremely sturdy and just starting to fruit now.April, if so do they need to be pruned back to ensure a second crop.

I just read a story about a farmer who said you should never plant Roselles in the same place as last season, they dont do well for some reason
