Dahlia Leaves Are Lighter Green Than Normal

Question From: Milton, New Hampshire, United States
Q: my leaves color is different its green and lighter green i dont see any insects.it does look as pretty as it was.

A: Dahlias are not happy in excessive heat. Keep the plants watered but the soil should not be sodden. The plants should begin to thrive when the temperatures cool a bit. Best And Happy Yardening, Nancy
