Our coneflower plant is under attack by something. The leaves look like they're being eaten but I can't find anything in the act. All I've found is whiteflies and they don't look large enough to make these holes (1/4 to 1 inch i diameter).
Nevertheless, I'm trying to get rid of the whiteflies. I first tried Ecoexempt, thinking it must have been something other than whiteflies but that didn't help. Then, I tried garlic pepper tea -- with and without seaweed. That didn't seem to bother them at all. Finally, I used Greenlight Brand Rose Defense Oil of Neem and that seemed to get rid of them. It's only been a couple of days so I'll see how that goes. Given the size of the holes in the leaves though, I still have some doubts about it being the whiteflies. I'm looking for a little reassurance that I'm on the right track.
I'll try to post a picture of my coneflower later.
Update#1: Here are some pictures of our coneflower that is under attack. You might notice the dark seaweed stains on the coneflower. That's residue from my GPT+Seaweed attempt.
