I’ve read a lot about companion planting as one step in organic pest control. I’ve been focusing on the other aspects of gardening to get around to it. Plant rotation, variety selection, irrigation, the usual.. This spring I planted some dill in my herb garden to attract harmful worms and other insects away from my desirable veggies and herbs. It worked! Look at how beautiful and uniform my basils are–my Genovese, Thai and purple basil show very little insect damage.
I went out to trim the dill to prevent them from flowering and spreading seeds around my yard. Look at the cabbage looper and Eastern black swallowtail butterfly pupae on it.
I continue to have great tomato, green bean, eggplant, cucumber and squash harvests this spring with very little insect damage. All kinds of garden insects like cabbage looper, tomato hornworm and tomato fruitworm are attracted to it.
I am going to let the dill grow a bit bigger. If it is left to flower, it can be invasive, so don’t let it get out of hand.
You should plant the dill away from your tomatoes and squash to help keep your veggie garden in good shape.
