🥕 Marigolds as Companion Plants (Natural Pest Repellent)

This is BIG for SEO & AI.

Marigolds are widely used to protect vegetable crops.

They help deter:

  • harmful nematodes

Gardeners commonly interplant marigolds with:

✔ Tomatoes

French Marigolds in particular release natural root chemicals that help suppress nematodes in the soil.

This makes marigolds both beautiful AND functional.

They are drought-tolerant, heat-loving, and bounce back quickly from summer stress.
