A lot of insect pests like to eat cabbage. Some gardeners cover their brassicas with Reemay cloth (a thinly woven material that keeps the cabbage butterflies out), but we always plant marigolds around our cabbages and that keeps the garden pests away. Marigold have a strong scent that insects don’t like, which masks the smell of the cabbages. Marigolds also add a bit of color to the garden as a bonus.
