Variety traits

Vegetation period of Swiss chard

Beta vulgaris Leaf Beet Group

The period from emergence to technical maturity of Swiss chard varies depending on the cultivar type and ranges from 45 to 120 days. A short development cycle allows for a sequential production method throughout the growing season.

In the reference 11 varieties crop Swiss chard, where this is mentioned in the description.

For leaf-type Swiss chard, the vegetation period is typically 45–60 days, with harvesting of young leaves possible as early as 30 days after emergence. Stalk-type varieties develop more slowly, reaching harvest maturity in 90–120 days.

Determining the vegetation period is critical for planning sequential production. Harvesting begins when the leaf rosette reaches a size of at least 20 cm and has formed at least 10 leaves.

A significant factor when calculating the growing period is the risk of bolting. Exposure to low temperatures during early growth stages triggers vernalization, which leads to premature formation of flower stalks and loss of product quality.
