Like most other vegetables, swiss chard is started from seeds. Swiss chard seed is actually a cluster of seeds. When sowing swiss chard, if more than one germinates, it is good to thin them to just one. But if you are growing them thickly, it is ok to put two to three in a bunch. I had always sown 3-4 plants in one place and had no problems.

Swiss chard seeds are buried about ½ an inch deep. They usually germinate in a week. They take longer to germinate during colder weather and shorter in summer. Use a good quality seed starting mix for starting your seeds. Alternatively, you can also use products like seed starting plugs to germinate seeds.
