Every season has its challenges when it comes to dealing with garden pests. We have several pests in zone 4 ranging from Japanese beetles, potato bugs, cabbage moths, flies and mosquitoes. I like to grow a combination of flowers and herbs in my garden to help keep pests at bay. Not only are these plants attractive they will help you avoid utilizing harmful insecticides. I grow Marigolds which keep certain types of beetles away and I add basil which will keep the flies and mosquitoes in check. By utilizing the right combination of flowers and herbs you are sure to have a pest free environment. Cheers
