Garden cress: complete guide

Overview

Garden cress (Lepidium sativum) is a fast-growing annual leafy vegetable from the Brassicaceae family. Originally from Central Asia and the Himalaya, garden cress is now cultivated worldwide and known for its nutritious leaves with a peppery, mustard-like flavor. It grows from seed to harvest-ready in just 2-3 weeks.

The plant reaches 20-35 cm in height and produces significantly more nutrition per square centimeter than most other leafy greens. It contains vitamins A, C, and K, plus minerals like iron and zinc.

Appearance & Bloom

Garden cress forms a compact rosette of fine, green leaves. The leaves are deeply lobed to feathery, soft and airy in texture. The stems are green, leafed, and fragile.

When allowed to flower (rarely desired for consumption), small white to pale-pink flowers appear in umbels, followed by thin, round seedpods of 6-8 mm.

Ideal Location

Garden cress thrives in full sun to light shade. Perfect for balcony planters, beds, and greenhouses.

• Light requirement: Full sun to light shade (minimum 4 hours sunlight)
• Drainage: Well-draining, moisture-retentive
• Temperature: 10-20°C ideal; frost-sensitive <5°C
• Height: 20-35 cm

Soil Requirements

Garden cress grows on nearly any rich, well-draining soil. A rich mixture of compost and garden soil gives best results.

• pH: 6.0-7.5 (neutral to slightly basic)
• Moisture: Moderately moist (no waterlogging)
• Nutrition: Light feeding (5-5-5 NPK or equivalent)

Watering

Maintain consistent 2-3 cm soil moisture. Underwatering leads to sharper taste; overwatering to rot.

• Frequency: Daily in warm weather, every 2 days in cool weather
• Method: Bottom watering to keep leaves dry
• Total need: 150-200 mm during growing period

Pruning & Maintenance

No pruning needed. Harvest leaves when 5-8 cm; younger leaves are more tender. Remove wilted or yellow leaves immediately.

Maintenance Calendar

• Spring/Summer: Sow every 2 weeks for continuous harvests
• Days 7-10: Germination
• Days 14-21: First harvest possible
• Days 21-28: Full plant ready
• Fall: Slower growth (cooler weather)

Winter Hardiness

Very frost-sensitive (dies <-2°C). Protected cultivation (greenhouse, tunnel) essential in autumn/winter.

Companion Planting

Combine in wide beds with:

• Lettuce (Lactuca sativa)
• Spinach (Spinacia oleracea)
• Radish (Raphanus sativus)
• Corn salad (Valerianella)
