Been growing them in Florida for at least 15 years. They do fine, grow and bloom monthly through our brutal summers here. Regularly in the 90s from May through September.
The fertilizer regimen above works great and my plants are huge and healthy. The only thing that kills a brug here is if they're planted in poor, sandy soil and the nematodes get to them. Even then they decline over a couple of years. So you have time to start anew from cuttings if you see one declining.
They're very lusty plants and lots of people grow them here.
