Plants that assist each other to grow well, repel insects or even other plants when grown next to each other is called companion planting and can be a sustainable and eco-friendly way to improve and protect your garden against unwanted pests and disease.
Chervil is one of the few herbs that grows better in shade, so planting it among taller plants is beneficial. It does not take well to being transplanted, so pick your spot and direct seed it in the spring. It is a good companion plant to radishes and will improve their growth and flavor.
The leaves resemble parsley in appearance and taste, with delicate overtones of anise. Sow seeds directly into the gardenabout three to four weeks before the last spring frost and again in late summer; thin seedlings to 6 to 9 inches apart.
