Should flower beds have a bottom?
While bottomless raised beds work well in most cases, there are times when adding a bottom makes sense: Pest Control: A solid bottom can keep burrowing pests like gophers, moles, and slugs out of your garden. If you live in an area with lots of critters, this might be a game-changer. As a general rule, put tall veggies toward the back of the bed, mid-sized ones in the middle, and smaller plants in the front or as a border. Consider adding pollinator plants to attract beneficial insects that can not only help you get a better harvest, but will also prey on garden pests.
