If you've ever wondered if Bacillus thuringensis (BT) really works, I had an excellent demonstration today. I've been using it every week to ten days, as a drench over my garden crop plants and onto the ground around them. This weekend I have been watering some untreated potted plants from my next door neighbor's back yard. She toted them around to the side in front so I can get to them without having to unlock her gate. Yesterday I killed one hornworm on a hanging plant, and this morning was astonished to find five of them on the skeletal remains of one of her other pots that was resting on the ground. Four were full-sized, one was about half that. I've had hornworm problems in previous years, but was too frugal with the BT. This year I want to keep my plants going. I'm not spraying, I don't want to harm butterflies, but I do want to keep these garden bulldozers out of my solanaceae plants that they favor (tomatoes, peppers, eggplant, potatoes). These are about 15 feet away from my lush tomato plants. I'm planning to give her some of my overage--it's funny, because she's the one that turned me on to organic gardening.
