Description
The marigold is a friendly companion in the vegetable bed. Its bright orange flowers attract beneficial insects, and its roots repel nematodes through root exudates. The petals are edible and give salads and soups a sunny color.
Care instructions
Sow from April directly into the bed; it germinates reliably and blooms all summer. Pinch out faded flowers regularly, then it will produce new buds tirelessly. It is tolerant, withstands drought well, and often self‑seeds.
