And you have predator bugs in your gardens? Dang again! The only creatures that I've ever seen here with other creatures on their backs are scorpions carrying their babies! I occasionally get some ladybugs and mantis' but not much else. And for years I have been growing lots of nasturtiums, borage, mints, dandelions, milkweeds, yellow marigolds, zinnias and goldenrod and they have never attracted good predators to help me. I have tansy all over the place along with fennel, dill, parsley and cilantro which I let flower and go to seed all summer. And I almost never see a predator! I figured growing these to attract them was just a lot of malarkey but now I'm guessing that it's because I'm in high desert country and they don't naturally live here. Color me green with envy. Happy gardening folks.
