Organic Rainbow Chard Seeds

Rainbow Chard is a favorite of children and adults! Packed full of vitamins and nutrients, colorful Rainbow Chard plants are as beautiful as they are nutritious. Grown on our farm for years, these productive and hearty plants show disease resistance and can perennialize in cooler coastal areas.

Planting by Zones

Zones 9-10

• Rainbow chard is a cool-season crop that thrives in cool and moist environments; in many parts of Zones 9 and 10, it can be grown year-round.

Zones 2-8

• Sow in early March or 10–12 weeks before transplanting outdoors.

Planting Rainbow Chard Seeds

• In Zones 9 and 10, begin seeds in starter pots or direct sow in the garden. If you direct sow, be sure to keep the garden soil moist the whole time the seed is germinating. In the warm weather of Zones 9 and 10, it may be easier to start by seed in a cool and protected area.
• When planting, place seeds on top of moist high-quality seed starting soil and cover with 1/2” of finely sifted soil. Follow the same planting steps to direct sow.
• Fertilize regularly with an organic liquid fertilizer once the seedlings have germinated and have the first set of true leaves.

Growing Rainbow Chard

• Once your seedlings are 7-8 weeks old, or 5-6” tall and stocky, you can plant them in the garden. Rainbow chard is an upright plant that needs appropriate spacing. Space at least 12” apart for full plant development. If the winter remains hot, use shade cloth or row cover for protection.

Growing Rainbow Chard in Containers

• Rainbow chard is an excellent container crop. Make sure your container is at least 20” deep. Keep in mind containers will dry out faster because they have more surface area and less soil to hold onto moisture. Mulch heavily on the top layer of soil in the pot to keep the soil from drying out or heating up too much.

Harvesting Rainbow Chard

• Harvest at any length. Baby chard can be harvested for use in salads and as fresh greens. Larger leaves are tasty in soups, stir-fries, and more. Use Rainbow chard like any dark leafy green.

Southern California Pro-tips

• Can be grown year round in areas of Zones 9 and 10 but production may decrease drastically in warmer months.
• Mulch heavily around your plants to ensure the soil does not dry out or heat up too much.
• During our hottest months of August, September, and October, plants can suffer from the heat. Using shade cloth can help protect the plants from extreme heat. In particularly warm winters, you may need shade cloth all season long.

Companion Flowers/Crops

• Rainbow chard grows great between Cole crops like broccoli, cabbage, and cauliflower. Good companion flowers are cosmos, gaillardia, and borage. We love growing Rainbow chard with Fordhook chard for variety!
