Has anyone done this? Would you do it again? For those not familiar, companion planting is where you plant specific plants together in order to compliment your main crop. I've only read Josie Jeffery's The Mix & Match Guide to Companion Planting. But I had a minor disaster in the last two spring/summers and am hoping to fix my issues (mainly hornworms and deer) without pesticide or putting up a taller fence (or murdering those fucking deer).
