The droppings give them away. If I have trouble finding hornworms that I know are there, I lean over and look at the foliage from a different angle, lower if possible.We got the second planting of sweet corn in the ground today along with some Lima beans. No if the Lima beans will just pollinate. The first time we planted them here we got 3 pods out of thousands of blooms. I think the heat may have been the culprit. I may plant some more later to set beans in September and see how that works. Still need to get okra planted ASAP. Have supplies to start the fall crop of tomatoes with. I'm a bit anxious about the tomatoes that are blooming now as any day now Tomato Horn Worms may attack. I can hand pick and feed them to the chickens if they will eat them. I know that they can be picked off easier at night when they come out to eat.
