What plants should never be grown near tarragon?

Tarragon will not do well when grown in the vicinity of incompatible companions that will affect its growing environment. Plants that require moisture can create humidity problems, while those that are heavy feeders can disrupt soil balance. I learned this firsthand when I planted tarragon alongside basil, and the tarragon developed mildew. Careful spacing avoids these types of problems.

Mint is the worst neighbor for tarragon. Its voracious roots rob tarragon of its nutrients and space. Mint requires constant moisture, which can cause root rot in tarragon. Keep them at opposite ends of the garden. My tarragon did much better after moving my mint containers away.

Basil has a covert compatibility issue. Both herbs appreciate sunshine, but basil's water requirements create humid microclimates. The humidity produced powdery mildew on tarragon leaves. Keep them at least 3 feet apart. My plants did not show any white spots after that change.

Soil nutrients essential for tarragon are depleted by heavy feeders like tomatoes and corn. They also require fertilization, which alters soil chemistry and reduces tarragon's flavor intensity. Keep them apart in separate beds or with a barrier plant. I solved this by planting chives in between.

Instead, opt for compatible herbs. Rosemary and thyme prefer the same dry conditions. Garlic repels pests by nature. Lavender promotes airflow. These companions will produce healthier tarragon. My herb spiral currently successfully groups these Mediterranean plants.
