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

Google about wilting in rosella.

I have no idea - try putting wilting of rosella into google. I would imagine they need a lot of water in the tropics. I had Chinese cabbage like that a month or so ago. A couple of days of warm weather and little water and they just wilted.

To all the questions about rosella planting - if you used this guide to look when to plant and harvest etc you wouldn't ask these questions. This website is a means for you to look up a plant (rosella) set what climate you live in and then read ALL the details about the plant. Plant time, time to harvest, if it is frost tolerant etc. Like if you are cool/mountain it says plant Nov /Dec -- so you don't plant until then.
