Your site is great! Full of useful information for organic garden beginners.

For cabbage worms, I use water alone to solve the problem; but you must be free to watch the butterfly from time to time. After white butterfly’s visit, pour rain water over the whole cabbage immediately; so that all the eggs will be shown; and you can whip them off before any development. If you use spray, the eggs laid in between of the heart of the cabbage will not be able to reach. Overall, it is fun to control all the organic garden pests by yourself.

Thanks again for sharing your information.
