The challenge of organic gardening is the bugs and caterpillars. Ughhh!!! Stinkbugs. The battle has begun in earnest now. Currently I am dusting the tomato plants with diatomaceous earth. It is ground sea creature shells. The dust is harmless to animals and humans, but when it comes into contact with the exo-skeleton of insects it's sharp edges cut them and they essentially bleed to death. A very gruesome death for an insect. Really though you ought to see how gruesome some of my tomatoes look right now.
There's nothing to do for the hornworms except to pick them off. I heard chickens love them. My chickens aren't so sure. When I threw them into the coop, the chickens pecked around at them a little cocking their little heads side to side and peering at the curled hornworm with a beady eye. I'm sure LuLu thought, "She expects me to eat this ugly thing? Bring me some more bread or squash already!"
