- Seeded or transplanted Swiss chard should be placed 6 inches apart in rows 12 inches apart.
- Dense planting will reduce weed pressure.
- Swiss chard grows best when temperatures do not exceed 75°F.
- Temperatures as low as 32°F do not seriously damage young plants.
Irrigation: Water Swiss chard regularly, applying 1 to 2 inches per week depending on the weather. Mulching around the plants helps to conserve soil moisture and reduces plant growth. For more information on watering, click here.
Fertilization: Apply ¼ cup of nitrogen-based fertilizer per 10 feet of row four weeks after planting to encourage rapid plant growth. Place fertilizer to the side of the plant and irrigate into the soil. For more information on fertilizing, click here.
Harvest: Swiss chard can be harvested when the leaves reach full size or anytime after they form. Older leaves are often stripped off the plants first, allowing the young leaves to grow. Swiss chard can be stored for one to two weeks if refrigerated.
