What plants can I use to create a physical barrier against hornworms?
I've read about using certain plants as barriers to deter pests, and I'm keen on trying that in my garden to protect my tomatoes from hornworms. I have space for companion planting, and I’m curious which specific plants can serve as effective physical or aromatic barriers. Growing in a community garden in a temperate area means I have a mix of sun and partial shade. Can anyone suggest the best plant combinations or placements that can help? I’m ready to get creative with my gardening strategy! ✨
