I live in the Atlanta area and have had Purslane plants throughout my garden for over 15 years. For the first time ever my plants stopped blooming. It's not just mine but the same thing is happening with my daughter and sister. Also the plants in the stores are not blooming so there is no need to buy new ones. They were beautiful when planted in the Spring and stopped blooming about a month ago. I have tried feeding every two weeks for six weeks. We have had 30+ days of temperature over 90 degrees so that is very hot for a long time. But this plant likes the heat so what could be the problem?
