How to Grow Garden Cress Seeds: Step-by-Step Instructions

Start with fresh, organic garden cress seeds from a reputable supplier. High-quality seeds ensure better germination rates and healthier plants.

2. Select the Right Growing Medium

Garden cress grows well in:

Potting soil: Light, well-draining soil rich in organic matter.

Hydroponic mats or cotton wool: Ideal for indoor microgreens.

3. Prepare Your Container or Garden Bed

Use shallow trays, pots, or garden beds with good drainage.
Fill containers with soil or growing medium, leveling the surface.
Lightly moisten the soil before sowing.

4. Sow the Seeds Correctly

Sprinkle seeds evenly over the surface; do not bury them deeply.
Cover lightly with a thin layer of soil or press gently to ensure contact.
Garden cress seeds require light to germinate, so avoid covering them too thickly.

5. Provide Optimal Growing Conditions

Light: Place in a bright spot with indirect sunlight or under grow lights.
Watering: Keep soil consistently moist but not waterlogged.

6. Germination and Growth Timeline

Seeds typically germinate within 2-3 days.
Thin seedlings if they become crowded to prevent stunted growth.
Maintain moisture and light; seedlings will grow rapidly.

Harvest when seedlings reach 5-7 cm (2-3 inches) tall, usually after 7-14 days.
Use scissors to cut above the soil level.
For continuous harvest, sow new seeds every 1-2 weeks.

Tips for Growing Healthy Garden Cress

Use filtered or room-temperature water to avoid shocking seedlings.
Avoid overwatering, which causes root rot.
Rotate trays or pots to ensure even light exposure.
