I have yet to see what is eating the leaves off my potted hibiscus plants, trumpet plant and a few other plants I have on my patio that are in pots! I have use the "home remedy" insect spray that was suggested on an earlier forum and it did absolutely no good. Today I bought a bottle of "Seven" insect killer. I feel helpless trying to fight something I can't see! I've staked out the plants in the morning, late evening and mid-day trying to get a glipse of what is eating my darn leaves! I've seen an worm on one plant which I promptly killed; but the next day more leaves were completely eaten. My trumpet plant is almost "leafless". Help!!!!!
