Advice from the seed producer and author

Yves Gagnon

Growing conditions for spinach

Spinach is frost-resistant. It produces well in cool spring and fall conditions. With the heat of summer, it stops its vegetative development and flowers. It thrives in well-structured, humus-rich organic or clay soils. It is best suited to sandy soil amended with mature compost and irrigated as needed. Spinach is demanding. Its soil should be amended with 1 t of mature compost per 100 m2. A pH between 6 and 7.5 is ideal for it. It is best to avoid using young compost, fresh manure, and nitrogen fertilizers when growing it.

Spinach Crop Rotation

Spinach 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, provided that fertilization is adapted to its needs.

Companion planting of spinach

Since spinach is sown early in the spring, it can be planted with late-season crops, such as cabbages, to save space. It also combines well with lettuce, chicory, lamb's lettuce, and arugula. It can be grown between rows of asparagus.
