Planting, Growing, and Harvesting Swiss Chard

Catherine Boeckmann

Learn how to grow Swiss chard鈥攐r simply 鈥渃hard鈥濃攁 member of the beet family. It does well in both cool and warm weather. It is a nutritional superfood, high in vitamins A, C, and K, as well as minerals, phytonutrients, and fiber. Plus, its rainbow of colors is beautiful! See our Swiss chard growing guide for information from planting to harvesting.

About Swiss Chard

Similar to beets, Swiss chard’s stems and leaves can be eaten cooked or raw. It is prolific鈥攍eave plenty of room in the garden bed! Its mild flavor adds nutrition and color to salads, pasta, pizzas, quiches, sandwiches, and more.

Swiss chard is very easy to grow, incredibly hardy, and a great choice for beginner gardeners. And it looks beautiful in the garden, with broad, thick stems available in colors ranging from pure white to golden yellow and even hot pink! 

Typically grown as a cool-season crop because it grows quickly and easily during the cooler temperatures of spring and fall, chard is quite tolerant of hotter temperatures, too. Its growth will slow down in summer, but chard’s higher heat tolerance makes it a great salad green to grow when it gets too hot out for the others.

Chard is a superfood, high in vitamins A, C, and K. It doesn’t have the bitter taste that many other greens have, and it makes a good substitute for spinach or kale if you’re not a fan of those superfoods. 

On top of all its virtues as a garden vegetable, chard is a lovely edible ornamental plant, coming in many different colors to mix with landscaping or in containers. Why, you could even use chard in a vase or bouquet, mixed with flowers, or on its own. Why should flowers have all the fun?

Planting

Chard will tolerate partial sun, but grows best in full sun. It prefers a location with moderately fertile, well-draining soil and a soil pH between 6.0 and 7.0 (slightly acidic to neutral). Before planting, mix aged manure and/or compost into the soil to boost soil fertility. Scatter a general-purpose organic fertilizer on the soil one week before sowing, then rake the soil to a fine tilth.

When to Plant Swiss Chard

  • For the spring season, plant chard seeds 2 to 3 weeks before the last spring frost date.
  • For a fall harvest, plant chard seeds about 40 days before the first fall frost date. (Many varieties will tolerate a light frost.)
  • Soak seeds in water for 24 hours before planting to speed germination. 

How to Plant Swiss Chard

  • When ready to plant, apply 5-10-10 fertilizer to the area.
  • Sow seeds 1/2 to 1 inch deep, 2 to 6 inches apart, in rows 18 inches apart.
  • Continue planting seeds at 10-day intervals for a month.
  • You can also start chard off in pots for transplanting later, which has the benefit of helping to prevent slugs from eating the young seedlings. This is also useful for succession planting, while you wait for space to become available in the garden. Once you鈥檝e cleared out the previous crop, transplant the sturdy chard seedlings in the garden one foot apart, leaving 16in between rows.

Growing

  • When plants are 3 to 4 inches tall, thin to 4 to 6 inches apart, or 6 to 12 inches if plants are large.
  • Use scissors to avoid disturbing nearby plant roots. You can eat the cuttings.
  • Chard usually does just fine without the use of fertilizer, but if yours seems to be staying small, consider applying a balanced fertilizer halfway through the season.
  • Water evenly and consistently to help it grow better. Water plants often during dry spells in the summer. Water regularly to promote plenty of fresh leafy growth and to stop the plants from running to seed, or 鈥榖olting,鈥 in dry weather. If they do bolt, they鈥檒l no longer produce new leaves, so dig them up and add them to your compost pile.
  • Mulch the plants to help conserve moisture and suppress weeds. Keep your chard weeded using a hoe. 
  • When plants are about 1 foot tall, cut leaves back to 3 to 5 inches to encourage new tender growth, if chard plants become overgrown, they become less flavorful.

Types

  • 鈥楤right Lights’: Dark green leaves on multicolor stems; bolt-resistant but less frost-hardy.
  • 鈥楩ordhook Giant’: Dark green leaves, white stems; compact plants.
  • 鈥楲耻肠耻濒濒耻蝉’: Green leaves, white stems; heat-tolerant.
  • 鈥楶别辫辫别谤尘颈苍迟’: Green leaves, pink-and-white striped stems; bolt-resistant; good for containers.
  • 鈥楻补颈苍产辞飞’: Red, pink, white, yellow, orange, and striped leaves and stems.
  • 鈥楻丑耻产补谤产’: Dark green leaves, deep-red stems; sow after risk of frost has passed or it may bolt.
  • 鈥楻uby Red’: Green leaves, bright-red stems; sow after risk of frost has passed or it may bolt.

Harvesting

  • Begin to harvest when the plants are 6 to 8 inches tall, depending on which size leaves you desire.
  • Cut off outer leaves 1-1/2 inches above the ground with a sharp knife. Avoid damaging the plant’s center. Eat what you cut.
  • Harvest regularly, and the plants will produce continually. Use the 鈥渃ut-and-come-again鈥 harvesting technique, taking the largest, oldest leaves and leaving the young ones to continue growing. 
  • In fall, position row covers over the plants to keep the harvests coming for longer.
  • To extend the harvest, lift the plant, with roots in the soil, and transfer to a container in a greenhouse. Maintain the temperature at around 50掳F. Initially, the chard will appear limp, but it should rebound.

How to Store Swiss Chard

  • Rinse off Swiss chard leaves and store them in the refrigerator in ventilated plastic bags.
  • To use, draw a sharp knife along the ribs to separate the leaves.
  • You can cook the ribs like asparagus (steamed, roasted, saut茅ed).
  • Cook chard leaves just like spinach. Strip the leaves away from the central stems, chopping them up and steaming or wilting them in a pan. The central stems can be cooked in the same way but take a little longer. They can be served with salt and melted butter, a rich hollandaise sauce, or dipped into the yolk of a soft-boiled egg.

Wit and Wisdom

  • Swiss chard originated in鈥攜ou guessed it鈥擬editerranean Europe! Oddly enough, chard is not native to Switzerland at all. According to legend, a Swiss botanist was responsible for determining chard’s scientific name, and the 鈥淪wiss鈥 just stuck!
