Herbs are the easiest companion plants to intersperse between food plants in order to increase yields. It can be done within the rows or between the rows of vegetables without harming the vegetables themselves. Herbs are strongly scented to attract beneficial insects or repel and confuse harmful pests. They are generally light feeders, so they won’t deplete the soil which robs the nutrients that vegetables need.
