In March I bought a rosa sinensis at Home Depot and planted it in a large unglazed clay pot. It has done really well, growing and producing lots of blooms. It even survived our June temps of 105-110. I was watering every other day and feeding once per week. Our monsoon season began, so I cut back on watering, only watering when we'd no rain for 2 days in a row. Still the plant did well. Now that we've not had rain for 4 days, the hibicus seems to be dying. All the leaves that are left are wilted and drooping. They are not crumbly-dry. I fed and watered yesterday - but no change. What should I do?
