I am having an ongoing problem with white flies eating up my marigolds. They are now sticks with blossoms. Every time I water or disturb the plant, a little cloud of white flies comes out of them. I have tried sprays, systemic fertilizers with the insecticide in the ground, and they still keep coming back. It all seemed to start when I planted pumpkins out there. I have since pulled up the pumpkins but the flies keep coming back.
