Choosing the right variety for planting chard
Varieties of chard cultivated in France
Several types of chard are commonly grown in France, adapted to local climatic conditions. Chard with broad white stalks is prized for its vigor and good cold tolerance. Green chard with white stalks offers regular growth and a staggered harvest. Chard with colored stalks, with red, yellow, or orange petioles, is the result of horticultural selections. Beta vulgaris and exhibit good resistance to temperature variations. These varieties are available as standard or improved seeds, selected for open-field cultivation.
Choose a variety according to the climate
Variety selection depends heavily on the regional climate. In temperate or oceanic zones, most chard varieties thrive. In warmer regions, varieties tolerant to bolting are preferable to extend the production period. In areas with harsh winters, hardy varieties capable of withstanding temperatures close to -5°C allow for extended cultivation into autumn and early winter, with light protection if necessary.
Adapt the variety to the soil and available space
Soil type also influences the choice of variety for planting chard. In deep, loose, and rich soil, varieties with large stalks fully express their potential. In more compact soil or when grown in narrow beds, varieties with a more compact habit make maintenance easier and limit competition between plants. In containers or raised beds, varieties with moderate growth allow for reduced spacing, generally 30 to 40 cm between plants, while ensuring even growth.
Where to plant chard in the garden
Ideal location for planting chard
Swiss chard thrives in a sunny to partially shaded location. Six to eight hours of direct sunlight per day promotes steady growth and good leaf development. In warmer climates, light shade during the hottest hours reduces water stress and slows seed production. A sheltered spot, protected from prevailing winds, reduces evaporation and protects the foliage, while also maintaining a more stable temperature around the plants. Beta vulgaris.
Planting in open ground
Planting directly in the ground is suitable for most situations. The location must be well-drained to prevent root asphyxiation. A flat or slightly sloping plot facilitates water runoff. Chard integrates easily into a crop rotation, following undemanding vegetables. A spacing of 40 to 50 cm between rows allows for good foliage development and simplifies maintenance and harvesting.
Growing in containers or raised beds
Planting Swiss chard in containers or raised beds is possible provided you have a container at least 25 cm deep. The volume of soil must be sufficient to ensure proper root development and a stable water supply. Containers should have drainage holes to guarantee effective drainage. A spacing of 30 cm between plants is recommended to avoid competition and promote balanced growth, even in limited spaces.
Prepare the soil before planting chard.
Recommended soil type
Chard thrives in deep, loose, and well-drained soil. Overly compacted soil restricts root development and slows growth. The ideal texture is balanced, neither too sandy nor too clayey, with good water retention. A slightly acidic to neutral pH, between 6,5 and 7, promotes the absorption of nutrients necessary for plant development. Beta vulgaris.
Soil amendments and enrichment
Before planting Swiss chard, adding organic matter improves soil structure and fertility. Mature compost or well-rotted manure can be incorporated to a depth of 20 cm, at a rate of 3 to 5 kg per square meter. This amendment promotes steady growth without excess nitrogen. In poor soil, a supplementary application of balanced organic fertilizer can be considered to support foliage development.
Soil preparation and drainage
The soil should be prepared several weeks before sowing or planting. Digging or loosening the soil to a depth of 25 to 30 cm aerates it and removes stones. Leveling the surface promotes even germination. In heavy soils, installing raised beds improves drainage and reduces waterlogging, which is particularly harmful to the root system at the beginning of the growing season.
Sowing, planting and taking cuttings to grow chard
Sowing to plant chard
Sowing is the most common method for planting chard. It is done directly in the ground, once the soil is sufficiently warm and loose. The seeds are sown in clusters of 2 to 3 seeds, 2 cm deep, with a spacing of 30 to 40 cm between clusters and 40 to 50 cm between rows. After germination, thinning is necessary to keep only one vigorous plant per location, ensuring good foliage development. Beta vulgaris.
Planting chard from seedlings
Planting young plants saves time in the growing cycle. The plants are planted at the same spacing as for sowing seeds. The crown should be level with the soil surface to prevent rot. Thorough watering after planting encourages root development and reduces water stress during the first few days.
Cuttings and division of clumps
Cuttings are not commonly used, but dividing established clumps can be used to renew a crop. This operation is carried out on well-developed plants, by taking rooted sections. Each section is replanted immediately, watered generously, and monitored until fully established, thus ensuring consistent production on the same plot.
Regular maintenance is essential for successful chard planting.
Suitable watering
Regular watering is essential for the continued growth of Swiss chard. The soil should remain moist but not waterlogged, especially during dry periods. Moderate but frequent watering promotes leaf development and reduces water stress, which causes the stalks to harden. Watering at the base of the plant, preferably in the morning, reduces the risk of moisture-related diseases affecting the foliage. Beta vulgaris.
Weeding and mulching
Weeding should be carried out in the first few weeks to limit competition for water and nutrients. Light hoeing improves soil aeration and promotes water infiltration. Applying a 5 to 8 cm layer of organic mulch helps retain moisture, reduces weed growth, and stabilizes soil temperature around the roots.
Thinning and maintenance of plants
After sowing, thinning is essential to maintain sufficient spacing between plants. Only one plant should be kept every 30 to 40 cm to avoid excessive competition. Regularly removing damaged or yellowed leaves stimulates the growth of new shoots and helps maintain vigorous plants throughout the growing cycle.

Planting Swiss chard: preparing the soil and choosing the location
Where to plant chard
Swiss chard thrives in a sunny or partially shaded location. Avoid consistently damp areas to minimize the risk of root diseases. Choose a spot sheltered from strong winds to prevent the broad leaves from being blown off.
Soil preparation
Chard prefers light, deep, well-drained soil rich in organic matter. Before planting, loosen the soil to a depth of 30 cm and incorporate 3 to 5 kg/m² of mature compost. Check the pH and adjust it to between 6,0 and 7,0 for optimal growth.
Rotation and companionship
Avoid planting chard after vegetables of the same family such as Beta vulgaris to limit soil depletion and the spread of disease. Combine them with vegetables like carrots or onions for better nutritional balance and natural protection against certain pests.
Planting Swiss chard: sowing, planting and propagation by cuttings
Sowing in open ground
Chard seeds can be sown as soon as the soil temperature reaches 10-12°C, usually in spring. Sow in rows spaced 30 cm apart, with 5 cm between seeds. Lightly cover the seeds with 0,5 cm of fine soil and keep the soil moist until germination, which generally occurs in 10 to 15 days.
