Rainbow Mix

Chard

50d to harvest

Tender, jewel-toned leaves unfurl in as little as 50 days, with crisp ribs that glow in a true rainbow—creamy white, golden, rosy pink, and deep emerald green. The texture is pleasantly snappy and smooth, with a gentle, earthy sweetness that holds its character beautifully in fresh salads and quick sauté-style skillet favorites, as well as silky sauces and vibrant pickles. Grow Rainbow Mix for a garden that looks like stained glass and a harvest that stays colorful from first cutting to the next.

Frequently Asked Questions

What disease or pest is most likely on Swiss chard (Beta vulgaris var. cicla), and how can I control it?

Watch for leaf miner and aphids, which commonly show up as tunnels in chard leaves and curled, sticky growth. Remove badly infested leaves early, then spray the undersides with insecticidal soap and repeat every 5–7 days until activity drops. If you see leaf spots or powdery mildew during humid weather, water at the soil line and improve airflow by thinning plants to avoid crowded foliage.

How often should I water Swiss chard during the main growing phase?

During the 40–50 day leaf growth period, keep the soil consistently evenly moist, aiming for about 1 inch (2.5 cm) of water per week total from rain and irrigation. Water deeply when the top 1 inch of soil dries, because chard in dry spells quickly turns bitter and stressed plants are more susceptible to pests. Avoid soggy soil; chard prefers moisture without waterlogging.
