Chervil, a delicate and aromatic herb, thrives in outdoor plant boxes when paired with the right companion plants. To create a flourishing chervil garden, consider these top plant choices:

1. Lettuce: A perfect companion, lettuce provides shade to chervil’s shallow roots, keeping the soil cool and moist.

2. Radishes: These fast-growing vegetables help break up compact soil, improving drainage for chervil’s sensitive roots.

3. Chives: Their strong scent deters pests that might otherwise target chervil, making them an excellent protective neighbor.

4. Spinach: Like lettuce, spinach offers shade and retains soil moisture, creating an ideal microclimate for chervil.

5. Parsley: Sharing similar growing conditions, parsley and chervil complement each other without competing for nutrients.

Avoid planting chervil near strong-scented herbs like mint or basil, as they can overpower its subtle flavor. For optimal growth, ensure your outdoor plant boxes have well-draining soil and partial shade, as chervil prefers cooler temperatures.

By selecting the right companions, your chervil garden will not only thrive but also enhance the flavors and health of your entire herb collection. Happy gardening!
