Marigold Companion Planting Guide
tips for growing marigold in your garden
Marigold Enhances.
Marigold, when planted nearby will help asparagus, basil, broccoli, cabbage, cucumbers, eggplant, gourds, kale, potatoes, squash and tomatoes. Marigold also makes a good companion plant to melons because it deters beetles.
Bad Companions for Marigolds.
Beans and cabbage are listed as bad companions for marigolds.
Marigolds, Cabbage & Broccoli.
Cabbage and I suspect it's fellow Brassica broccoli appear to be questionable companions. Since neither of our conflicting sources mentioned why they felt positively or negatively about cabbage as a companion, it might be best to assume the worst and consider both broccoli and cabbage as bad companions for marigolds.
Marigold attracts.
Unfortunately, marigolds attract spider mites and slugs.
Marigold repels many harmful insects.
Scented varieties of marigold will deter beetles, beet leaf hoppers, Mexican bean bettle and nematodes. Pot marigold repels asparagus beetle and tomato worm and Mexican marigold is thought to repel rabbits.
Marigolds as a pesticide.
The roots of French marigolds produce a chemical that is so strong it is an effective pesticide for years after the plants are gone.
Mexican marigolds produce a stronger version of this chemical which has the potential to inhibit the growth of some of the more tender herbs.
