Sunpatien Impatiens Stopped Flowering

Question From: L. Perry - West Branch, Michigan, United States
Q: I planted sunpatiens and they looked beautiful up until now. They have stopped flowering and I just have the green bush. They get morning and afternoon sun and then in the later afternoon (like now about 2 pm) they get some shade. Up until now they have been beautiful bloomers, but for the last 2 weeks, I have had no flowers. Can you tell me what is wrong.

A: Excessive heat would be my best guess. Now that the weather has cooled down they should pick up flowering. Best And Happy Yardening, Nancy.
