Swiss chard

Beta vulgaris (Cicla Group)

Broad green leaves and colorful stalks bring an edible splash of color to beds and large pots.

Make it part of your growing collection.

A LITTLE EVERYDAY CARE

Help it thrive.

A few things worth knowing.
01

Pick outer leaves

Cut outer stalks near the base, leaving central leaves to grow.

02

Water for leafy growth

Water young plants and containers regularly; help established plants through prolonged dry spells.

03

Leave space around the crown

Mulch around plants to conserve moisture, keeping mulch clear of the stalk bases.

Data sources & uncertainty
Sunlight

Sun and some shade are described; 2+ hours is a broad category, not a yield guarantee.

Source · checked 2026-09-20
Moisture

Moisture-retentive soil and watering through dry spells support leaf production; established plants tolerate some drought.

Source · checked 2026-09-20
Soil pH

Numeric preferred pH range given in the growing description.

Source · checked 2026-09-27
Drainage

Free drainage is recommended; the ordinal interval is an interpretation, not a measured drainage rate.

Nutrients

No comparable numeric nutrient requirement verified; excluded from scoring.

Source · checked 2026-09-20
Soil texture

No specific soil textures verified; excluded from scoring.

Source · checked 2026-09-20
Plant spacing

RHS gives 30 cm within rows and 45 cm between rows; 40 cm is a simplified square allowance, also matching its minimum pot width.

Source · checked 2026-09-20
Growing depth

40 cm follows the RHS minimum container depth, not a measured root limit.

Source · checked 2026-09-20
Typical height

Approximate planning height; cultivar, pruning and growth stage change the result.
