What’s the best time of year to apply copper fungicide in my flower beds?
As someone who has been nurturing my garden for many years now, I'm always looking for ways to protect my cherished perennials. In my flower beds, I have a mix of echinacea and rudbeckia, which I've planted for their beauty and ability to attract pollinators. This year, I’ve started to notice some powdery mildew on the echinacea, and I’m considering using copper fungicide. I'm curious about timing – when is the best time in the growing season to apply it for maximum effectiveness? Should I apply it before I see symptoms, or only after they show up? I'd appreciate any insights from fellow gardeners! 😊
