How to Grow Swiss Chard

Swiss chard seed can be sown in situ or by transplanting seedlings when it reaches approximately 2″ (5 cm) in height. We recommend using quality seeds to have a superior germination rate (Order here).

The seeds can be left in a container of water for 24 hours to facilitate germination as with beet seeds. Subsequently, the seeds should be planted at a depth of 1″ (2.5 cm) when planted directly in the soil. If rows are to be used, each seed should be planted 3″ (8 cm) apart. Since Swiss chard needs a lot of space for the roots to grow, each row should be spaced 18″ (45 cm) apart. On the other hand, if it is going to be planted in a pot, you should put one per pot with a minimum depth of 10″ (25 cm).
