Swiss Chard

Enjoy nutritious greens during colder weather when you’re growing Swiss chard!

Swiss ChardSunlight: Full sun to partial shade
Maturity: 50-65 days
Height: 1 to 2 feet
Spacing: 6 to 18 inches apart, 12 to 18 inches between rows

An excellent source of vitamins A, K and C, as well as several minerals, home gardeners growing Swiss chard are rewarded with its succulent, mild-flavored leaves that can either be eaten raw or cooked like spinach. Easy to grow and perfect for edible landscapes or a container. Frost and heat tolerant.

Swiss chard is a member of the beet family (Chenopodiaceae) but unlike the beet, which is grown for the edible root, chard is grown for its vibrant green foliage and colorful stalks.

Quick Guide

  • Grows spring through fall
  • Look for varieties with brightly-colored stems
  • Direct seed 2-4 weeks before last frost into nutrient-rich, well-drained soil; water regularly
  • Harvest 50-65 days after planting seeds by cutting outer leaves ½ in. above the ground
  • Very few pests, but watch for flea beetles

Site Preparation

Swiss chard is best grown in soil that is rich in organic matter, drains easily and is high in nitrogen. It requires full sun (but tolerates partial shade) and regular water. Work composted chicken manure or blood meal into the soil to boost nitrogen levels. Foliar applications with an all-purpose organic fertilizers and liquid kelp 2-3 times during the gardening season will boost production.

How to Plant

Make your first plantings directly into the garden two to four weeks before the last expected frost. Sow seed 1/2 inch deep and 1-3 inches apart. Thin rows as plants mature and eat the tender shoots in salads. Chard is a prolific grower and can tolerate mild frosts.


Harvest outer leaves 1/2 inch above the ground as plants mature (5-6 inches tall), and new leaves will form in the center of the plant. Continue harvest until plants bolt in late summer. Save seed for future crops. Chard matures in 50-65 days from seed.

Tip: Swiss chard does not store well, so keep refrigerator storage time to a minimum.

Insects and Diseases

Insects are not commonly found on chard, but keep an eye out for flea beetles early in the season. They are small (1/10 inch long), shiny, dark brown or black beetles that damage plants by chewing numerous small holes in the leaves. Occasional aphids may attack, however this will typically occur later in the summer when the vegetable turns slightly bitter and is less appealing.

Seed Saving Instructions

Biennial. Varieties must be separated by 1/2 mile when going to seed. Will overwinter in mild climates if well mulched. In northern climates, trim leaves to 2 inches and store roots in sawdust or sand in a root cellar. Roots will store 4-6 months at 32-40˚F. Replant in the spring and harvest seed heads when dry.
