Last summer our first organic garden was quite successful. We live in northern Nevada (zone 4 or 5 - I think). We have a small backyard plot. Our garden was invaded by those catapillar worms early on. They did manage to destroy all the spinach and much of the lettuce. I tried a variety of methods to get rid of them, but basically they disappeared in their own sweet time. Is there anything I can do early this season to prepare for them? Is there any way I can make the garden less desirable for them? They were the only pest we really had to deal with, but they ate so much! Even hollyhocks! Any advice is appreciated.
