Yellow Leaves On New Guinea Impatiens In Yard
On all of my New Guinea Impatiens, they look like impatiens but can take the heat of summer, the leaves are turning yellow. They were green for most of the summer. I just fed them the Miracle Grow bloom booster liquid food. Some returned to green but the majority are still yellow. Could I be overwatering them? It's been 90 degrees every day this week and I've been watering the flower beds every morning.
