But something, I think aphids, are eating through them. Any tried and true solutions to this?
When you say "eating through", are there actually holes in the leaves? The reason I ask is that aphids do their damage by piercing the leaf surface with their mouthparts and suck out the fluids, so you won't see a whole lot of damage unless you look very closely, maybe with a hand lens. It's really important to identify the the pest you're trying to control before you take action to control it as your control measures may not work against the pest that's actually creating the problem. Kinda like a golden rule we were taught in Ag school.
Yeah, there are actually holes in the leaves. Later today I will take some pictures and post. I just kind of assumed aphids, maybe I'm completely wrong. Thanks.
