Sprayed bug spray for Roses on Knockout rose, Hollyhocks and Zinnias about a week or so ago.
The Hollyhocks at the side of the house were too far gone and will likely die. But the ones at the garden and by the side garage started getting better immediately. Hollyhocks leaves were turning yellow with brown bumps. And their were bug eggs on them, that when hatched devoured the leaves. Make sure to do this earlier next year!!
Spray also halted leaf problems that had begun on the Knockout as well as on the Zinnia starts.
