I am fairly new in the gardening business and have sunflowers, primroses, morning glories, zinnia’s, and hollyhock’s. Unfortunately, bits of the leaves on my hollyhock’s keep going missing when I wake up in the morning. None of my other flowers have been getting eaten. I have thoroughly looked at the leaves and find no bugs, and all my plants are in a pool cage. At first I thought maybe the sun was burning the leaves because they need mostly shade, so I moved it to a shadier area, but to no avail. I believe it to be the work of japanese beetles or something similar because it happens at night. I am going to examine them tonight to test my theory. If I do find beetles on the plant, how do I get rid of them without hurting the plant besides picking them off? Thanks, Jeremy.
