There’s very few pest problems in the square foot garden. I do have issues with snails and slugs because of the many greens I grow year round. I have methods to take care of those and they work, but it does take a little bit of time. Truth be told, I spend more time controlling slugs than I do weeding. The basic rotation of root/fruit/leaf is not only a good way to get lots of variety, but its a great way to cut down or eliminate garden pests. I had radishes (root) in the front squares during the early spring, followed immediately by transplanted lettuce(leaf), and now beans(fruit). No bug issues here! Growing in the back of the box is my favorite variety of spaghetti squash. And there’s lots of them!
