Watch out for

Honey fungus: Improve drainage and remove infected plants; avoid replanting in the same spot for several years.

Root rot: Ensure well-drained soil or containers with drainage holes to prevent waterlogging.

Winter dieback: Grow French tarragon in a container and move to a sheltered, frost-free location over winter.

Slugs and snails: Use physical barriers like copper tape or organic slug pellets to protect young growth.

Powdery mildew: Ensure good air circulation and avoid overhead watering; remove severely affected leaves.
