How to Grow Cress

Cress

Cress

Lepidium sativum

vegetable

Cress is a fast-growing, peppery-flavored leafy green that can be harvested in just 1-2 weeks from seed. Also known as garden cress, it produces delicate, feathery foliage and small white or pale pink flowers if allowed to mature. It's an excellent choice for quick harvests, microgreens, and container gardening.

Growing Conditions

☀️
Sun: Full sun to partial shade, 4-6 hours of sunlight daily; tolerates some shade, especially in hot climates
💧
Water: Keep soil consistently moist but not waterlogged; water regularly to prevent bolting; shallow, frequent watering works well for microgreens
📏
Spacing: 3-6 inches apart for mature plants; closer spacing acceptable for microgreens inches
📅
Days to maturity: 10-21 days
🌱
Planting depth: Surface sow or press seeds lightly into soil; barely cover with soil as seeds need light to germinate

Soil

Type: Light, well-draining loamy soil
pH: 6.0-7.0
Amendments:
Compost aged manure peat moss for moisture retention

Growth Stages

1

Germination & Seedling

3-7 days

Seeds sprout in 3-5 days; tiny seedlings with cotyledons (seed leaves) emerge, followed by the first true leaves

Keep soil moist; provide indirect light once sprouted; thin seedlings if crowded to prevent damping off

2

Vegetative Growth

5-14 days

Feathery, finely-divided true leaves develop; plant grows compact and bushy with delicate foliage

Water consistently; maintain cool temperatures (50-70°F ideal); provide good air circulation; avoid high heat

3

Maturity & Harvest Ready

2-3 days (optimal harvest window)

Plant reaches 4-8 inches tall with full, tender foliage; leaves are crisp, peppery, and at peak flavor

Monitor for early flowering signs in warm weather; harvest promptly before plant becomes too tall or bolts

4

Flowering

7-14 days

Tall flower stalks emerge with small white, pale pink, or purplish flowers; leaves become tougher and more bitter

Can allow some plants to flower for seed collection; flowering indicates plant is past prime culinary stage

5

Seed Production

14-21 days

Small seed pods (silicles) develop; plant becomes woody and inedible; seeds mature for collection

Allow pods to dry on plant before harvesting seeds; store in cool, dry location for next season

Common Pests

  • Use row covers; spray with neem oil or insecticidal soap; ensure adequate moisture to reduce stress

  • Hand-pick caterpillars; use Bt (Bacillus thuringiensis); apply row covers to prevent egg-laying

  • Spray with water to dislodge; use insecticidal soap; introduce beneficial insects like ladybugs

  • Improve drainage; ensure good air circulation; avoid overwatering; use sterile seed-starting mix

Uses

🍳

Fresh salads & garnish

Culinary

Cress adds a peppery, mustard-like flavor to salads, sandwiches, and soups. It's commonly used as a delicate microgreen garnish for upscale dishes and provides a nutritious crunch to fresh preparations. [source]

🍳

Watercress substitute

Culinary

Garden cress provides a similar peppery punch to watercress and can substitute in recipes when watercress is unavailable. It's less watery than watercress but offers comparable flavor and nutritional benefits. [source]

💊

Nutritional supplement

Medicinal

Cress is rich in vitamins A, C, and K, plus minerals like iron and calcium. Traditional herbalism values it for supporting digestion, respiratory health, and providing antioxidants. [source]

🏠

Fast-growing indoor crop

Household

Cress is ideal for indoor microgreen production on windowsills or under grow lights, providing fresh greens year-round with minimal space and effort. It's perfect for teaching children about growing food. [source]

🦋

Pollinator support

Wildlife

When allowed to flower, cress produces small white or pale flowers that attract bees and other pollinators, supporting garden ecosystem health. The flowers are also edible with a mild peppery flavor. [source]

Harvest Tips

Harvest when leaves are 2-4 inches tall, usually 10-21 days after sowing. For microgreens, cut just above soil level with scissors when cotyledons are fully expanded (5-7 days). Cut outer leaves continuously for repeated harvests, or cut the entire plant at soil level. Best harvested in the morning for maximum crispness. Use immediately or store in refrigerator in a plastic bag for up to 5 days.

Fun Facts

  • 🌱 Cress is one of the fastest-growing edible plants, ready to harvest in as little as 10 days, making it perfect for impatient gardeners and children's projects.
  • 🌱 In traditional European cuisine, cress was historically served as a spring tonic and was believed to have medicinal properties for blood purification and respiratory health.
  • 🌱 Garden cress seeds are mucilaginous, meaning they develop a protective jelly-like coating when moistened; this is why they were historically used in herbal medicine preparations.
