Think of your garden as a family, and plant it similarly to seating guests at a Thanksgiving dinner (which will hopefully feature some of your fall harvest!). You can seat Aunt Samantha anywhere and she’ll liven up the table. You want to put Aunt Olivia near the nieces she never gets to see so they can all catch up and have the best time possible.
At the same time, you might want to seat those relatives with equally passionate yet widely different political views far apart.
It’s the same with plants. Though tomatoes and potatoes are both in the nightshade family, they should never be planted together, as they share the same pests and diseases, which can be easily spread between them and decimate both crops. In fact, they shouldn’t even be planted one after another, for the very same reason. Yet both benefit from hanging out with onions and garlic, which repel their most popular pests. Intrigued?…
