Related question: do you know of any systemic miticides that would work? In addition to the mites being all over the phlox, they seem to have attacked the creeping charlie (ground ivy?) weeds in my lawn. Now, I really don't care about the weeds being harmed. But I do worry that all those weeds are a reservoir for the mites.
Any ideas?
I have lots of tall phlox all around my property & have sharred with many neighbors. With all my perennials, as soon as they don't look nice, I cut them back. It will not hurt them & they will come back fine next spring. I have so many now that I try to cut them back before they go to seed I use a combination "Insect & Disease" control product - this year was a Spectracide product.
