If you’re a salad lover, you’re probably familiar with the peppery, fresh taste of watercress. While this leafy green thrives in clear, slow-moving water, making it seem challenging to grow at home, watercress is actually a versatile plant that can adapt to many growing conditions.

In this guide, we’ll go over some simple methods to grow watercress successfully in your garden or containers, so you can enjoy a fresh supply of greens all season long.

However, with proper care and moisture, watercress can be grown in soil, containers, or even in shallow water settings.

This plant can be grown from seeds, cuttings, or transplants, so there’s flexibility depending on your preference and resources.

Growing Watercress from Seed

Growing watercress from seed is a popular method and allows you to control the entire growing process from start to harvest.

Step 1: Preparing the Soil

Choose a sunny spot in your garden and amend the soil with 4-6 inches (10-15 cm) of composted organic matter. Dig the compost to a depth of 6-8 inches (15-20 cm) to improve moisture retention and nutrient content, creating an ideal growing environment for watercress.

Step 2: Sowing the Seeds

Watercress seeds are very small, so you only need to lightly sprinkle them over the prepared soil. Sow seeds three weeks before the last frost date in your area, as watercress germinates best in cool temperatures between 50-60°F (10-15°C).

Keeping Moisture Levels Right

Since watercress loves moisture, it’s essential to keep the soil consistently moist. Avoid letting it dry out, but also ensure it’s not waterlogged, as overly wet conditions can harm the plant.

If growing watercress in containers, place them in a shallow saucer filled with water to help retain moisture, making it easier to keep the roots hydrated.

Growing Watercress in Containers

Growing watercress in containers is a practical option, especially for those without garden space. A wide, shallow container is ideal, as it allows water to spread evenly around the plant.

Simply fill the container with rich potting soil, sow the seeds, and place the container in a sunny location. Keeping the container in a saucer with water is beneficial, as it mimics the plant’s natural habitat and ensures consistent moisture.

Transplanting Seedlings

Seedlings should appear within five days of planting. When the seedlings are ready to be repotted, wait until all risk of frost has passed. Space plants about 8 inches (20 cm) apart to allow for healthy growth and airflow.

Growing Tips for Healthy Watercress

Sunlight: Ensure watercress receives plenty of sunlight, as this promotes faster growth and a stronger flavor.
Cool Temperatures: Watercress thrives in cooler conditions, making it a great option for early spring or fall growing.
Consistent Moisture: Regular watering is key. For soil-grown plants, check daily to ensure the soil is evenly moist, especially in warmer weather.

Harvesting Your Watercress

Watercress grows quickly, and you can start harvesting within a few weeks after planting. Simply snip the stems and leaves as needed, cutting above the soil level to encourage more growth. Regular harvesting helps maintain the plant’s health and promotes continuous production.

Growing watercress at home provides a fresh, peppery addition to your meals and is an enjoyable project for gardeners of all levels.

With the right care, you’ll have a reliable supply of flavorful greens from your own garden or container. Enjoy the freshness of homegrown watercress!
