I'm thinking ahead to the next growing season and how best to combat the flea beetles that always destroy my Brassicas. I rent a plot in a community garden, so I don't have as many options as I would on my own land. In looking at your alcohol spray, it seems a little heavy on the alcohol, and I wonder if it might burn young plants. Is there a minimum ratio of alcohol to water that would still be effective against these pests, or is it just trial and error? Also, I have heard that vinegar can help. Do you have any thoughts on this and what might be a good ratio of vinegar to water to deter the beetles but not damage the plants? Thanks.
