Planting Schedule

Add Rainbow Mix to your garden to build a schedule and get reminders.

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.

Culinary Notes


Chef's Note

Rainbow Mix chard hits that rare sweet spot: tender leaf, rib still snappy, and a mild green bitterness that plays nice with bright acid. It’s built for fast heat and fast dressing—anything slow will soften the crunch that makes this one feel jewel-bright on the plate.

Best Uses

  • quick skillet sauté where the ribs stay pleasantly firm
  • chopped salad with a creamy or citrusy dressing (it holds shape)
  • silky chard purée or blended sauce for pasta
  • quick pickles—especially with the rainbow rib thickness

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.
How do I tell when my Swiss chard is ready to harvest?
Begin harvesting around 45–50 days after sowing when outer leaves reach about 8–12 inches long and are thick enough to hold upright. Pick individual outer leaves first (near the base of the leaf stalk) and leave the center crown intact for continued regrowth. For best flavor, harvest before leaves become very large and tough.
