People grow herbs for cooking, traditional medicines, dyes, perfumes and lotions, or simply to add beauty to their garden. While generally easy to grow, some herbs should not be planted together because they emit chemicals that are toxic to another plant. Other herbs should not be planted together because they thrive in totally different conditions. Finally, some herbs should not be planted together because one will take over and crowd out the other.
According to Rodale's "Ilustrated Encyclopedia of Herbs," while there is little research to explain why certain herbs harm others, gardeners have observed the same results for generations. Rue should not be planted near basil or sage. Sage should not be planted near any member of the onion or garlic family, including chives. Coriander should not be planted near fennel.
Different herbs thrive in different growing conditions. Each herb grows best in a certain type of soil, a certain kind of light, and each needs a specific amount of moisture. Herbs like bay laurel and lemon verbena thrive in hot climates and die if there is a freeze. Others, like nasturtium, dill and rosemary, thrive in full sun, so they should not be planted with a shade-loving herb like sweet woodruff.
Some herbs grow prolifically and take over large patches of space; do not plant these herbs next to more delicate varieties. Mint herbs all spread above and below ground. Tarragon takes over large areas. These herbs will quickly overcome a smaller plant like chamomile.
