Advice from the seed producer and author

Yves Gagnon

Growing conditions for Swiss chard
Swiss chard withstands light frosts well. Unlike spinach, it responds well to heat. It prefers clayey, well-drained soils rich in humus. It still grows well in light, well-amended soil; however, soil moisture must be constant. The species is demanding. The soil can be amended with 500 kg to 1 t of mature compost per 100 m2. Nitrogen fertilizers should be avoided.

Swiss Chard Crop Rotation

Swiss chard is grown in the second year of rotation after a crop requiring young compost. However, it can be grown at the head of the rotation with appropriate fertilization.

Companion planting of Swiss chard

Swiss chard is usually combined with other leafy vegetables.
