Avoid: tomato & fennel
AvoidTomatoes with Fennel
Fennel can allelopathically stress some neighbors; tomatoes near vigorous fennel often look unhappy. Keep fennel in its own corner or container.
In the garden
- If you love both, separate by several feet or a path, or grow fennel in a pot.
Spacing & timing
Harvest bulbing fennel before it drops seed across the bed.
