Introduction to Garden Cress: What It Is
Garden cress (Lepidium sativum) is very easy to grow and can be harvested just two weeks after sowing. The annual crop plant belongs to the cruciferous family (Brassicaceae) and originates from the Near East. It is an undemanding plant that grows between 12 and 20 inches (30 and 50 centimeters) high. It grows from a spindle-shaped root. The stems are glabrous, bluish green and branched at the top. Pinnate, light green, alternate leaves are attached to them. From June to August, the tiny white flowers appear. The seedlings contain high levels of vitamin C, carotene and mustard oil glycosides, which are responsible for the spicy-hot flavor. Garden cress is a popular kitchen seasoning that is good on breads, in salads, soups and cut into cottage cheese. It is also an ingredient in Frankfurt green sauce.
Getting Started: Tools, Supplies, and Soil Preparation for Growing Garden Cress

Once you have prepared your soil, it’s time to start planting your garden cress seeds. Here’s what you need to know about selecting, sowing, and spacing your seeds:
- Choose high-quality garden cress seeds from a reputable supplier. Look for seeds that are fresh, plump, and uniform in size.
- Consider buying organic seeds if you’re looking to grow it without pesticides or other harmful chemicals.
- Sow the seeds directly into the prepared soil in rows or scattered across the planting area.
- Sow the seeds thinly and evenly, spacing them about 1/2 inch (1.3 cm) apart.
- Cover the seeds with a thin layer of soil, about 1/4 inch (0.6 cm) deep.
- Water the soil gently but thoroughly to ensure the seeds make good contact with the soil and have adequate moisture to germinate.
- Garden cress can be planted in rows or scattered across the planting area.
- If planting in rows, space the rows about 6-8 inches (15-20 cm) apart.
- If planting in clusters, space the clusters about 4-6 inches (10-15 cm) apart.
- Thin out seedlings once they emerge so that they are spaced about 2-3 inches (5-8 cm) apart. This will give each plant enough room to grow and develop.
With the right seed selection, sowing, and spacing, you’ll be on your way to a successful harvest in no time.
Watering and Fertilizing: Tips for Optimal Growth and Yield
- Garden cress needs consistent moisture to grow and thrive, so it’s important to water your plants regularly.
- Water deeply and thoroughly once or twice a week, depending on weather conditions and soil moisture levels.
- Avoid overwatering, which can lead to waterlogged soil and root rot.
- Water in the morning or early afternoon to allow the leaves to dry before evening, which can help prevent fungal diseases.
- Garden cress is a fast-growing plant that benefits from regular fertilization.
- Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium, or a fertilizer specifically formulated for greens and herbs.
- Apply fertilizer once a month during the growing season, following the package instructions for the correct amount and application method.
- Avoid over-fertilizing, which can lead to excessive leaf growth and poor flavor.
Other Tips for Optimal Growth and Yield
- Garden cress prefers cooler temperatures and partial shade, so consider planting it in a spot that gets morning sun and afternoon shade.
- Watch out for pests like aphids, slugs, and snails, which can damage or kill the plants. Use organic pest control methods like handpicking or using insecticidal soap or neem oil.

Troubleshooting Garden Cress Problems: Common Issues and Solutions
While garden cress is a relatively easy plant to grow, it can still face some common issues that may affect its growth and yield. Here are some of the most common problems that you may encounter when growing it indoors or outdoors, and some tips on how to address them.
- Poor germination: If the garden cress seeds are not germinating, there could be a few reasons for this. One possibility is that the seeds are old or have been stored improperly. Make sure to use fresh, high-quality seeds and store them in a cool, dry place. Another reason for poor germination could be that the soil is too dry or too wet. The seeds require moist soil to germinate, so make sure to keep the soil evenly moist, but not waterlogged. Finally, the temperature may be too low or too high for optimal germination. Garden cress seeds germinate best at temperatures between 55 and 70°F (13-21°C).
- Slow growth: If your garden cress is growing slowly or not at all, there may be several reasons for this. One possibility is that the soil is not rich enough in nutrients. It requires well-draining soil that is rich in organic matter. If your soil is lacking in nutrients, you may need to amend it with compost or fertilizer. Another reason for slow growth could be that the plants are not getting enough light. The plants require at least 4-6 hours of direct sunlight per day or 12-16 hours of artificial light if growing indoors. If your plants are not getting enough light, consider moving them to a sunnier location or investing in grow lights.
- Bolting: Bolting is when a plant produces flowers and seeds prematurely, usually due to stress such as high temperatures or insufficient water. Garden cress is a cool-season crop that prefers temperatures between 55 and 70°F (13-21°C). If the temperature gets too high, the plant may bolt. To prevent bolting, make sure to keep the soil evenly moist and provide shade during the hottest parts of the day. If bolting has already occurred, it’s best to harvest the plant and start over.
- Pests: Garden cress can be susceptible to several common garden pests, including aphids, slugs, and snails. To prevent these pests from damaging your plants, make sure to keep the garden area clean and free of debris, which can harbor pests. You can also use insecticidal soap or neem oil to control aphids, or handpick slugs and snails and dispose of them in a bucket of soapy water.
- Diseases: They can be susceptible to several fungal diseases, including damping off and leaf spot. To prevent these diseases, make sure to plant it in well-draining soil and avoid overwatering. You can also use a fungicide to treat any fungal infections that may occur.
By addressing these common issues, you can help ensure that your garden cress plants grow healthy and strong, and produce a bountiful harvest. With a little care and attention, you can enjoy fresh garden cress year-round, whether grown indoors or outdoors.
