How to Plant Watercress from Seed

When to Plant Seeds

  • Indoors: Start seeds 6-8 weeks before the last frost date.
  • Outdoors: Sow directly in the garden in early spring or fall.

Preparing the Planting Site

  1. Select a container, hydroponic system, or moist garden bed.
  2. Use rich, loamy soil if planting in the ground.
  3. Ensure access to clean, slow-moving water for aquatic growth.

Direct Sowing Outdoors

  1. Scatter seeds in a shallow water source, hydroponic system, or moist soil.
  2. Press seeds gently into the surface.
  3. Keep consistently moist and provide shade if temperatures are warm.
  4. Thin seedlings to 6-8 inches apart once they appear.

Sowing Seeds Indoors

  1. Fill seed trays with moist potting mix.
  2. Sprinkle seeds evenly on the surface and press lightly.
  3. Cover with a thin layer of soil.
  4. Keep soil consistently moist but not waterlogged.
  5. Place in a warm location (65-70°F/18-21°C).
  6. Germination occurs in 5-7 days.
  7. Transplant seedlings when they are 2-3 inches tall.

Pro Tip

Watercress thrives in constantly moist soil, so grow it near a water source or in a container with shallow water. For the best flavor, harvest young leaves regularly before the plant flowers.

Bonus: Snipping the stems often encourages fresh, tender growth!

Getting to know your Watercress

Watercress is a fast-growing aquatic or semi-aquatic leafy green with a peppery flavor. It thrives in clean, flowing water or consistently moist soil in partial shade. The plant is rich in vitamins A, C, and K. Watercress spreads quickly and is often grown in shallow containers or near water sources. It requires frequent harvesting to prevent flowering, which can cause bitterness.

Our Seed Safety Promise

We do not sell genetically modified seeds — ever. And we don’t use genetic engineering to breed new varieties. Instead, our skilled breeders use traditional, natural crossing methods to create hybrid seeds that are healthy, safe, and packed with potential.

Our Seed Quality Guarantee

At Shido, we believe great gardens start with great seeds — and that means quality comes first. Every seed lot we offer is ensure to generate top-notch germination because your garden deserves nothing less.

To keep our seeds at their peak, we run thorough pathology tests at trusted outside labs. When you open a Shido seed packet, you can trust it’s been nurtured, tested, and approved to give you strong, healthy plants from the very first sprout.

Types of Seeds We Offer

Hybrid Seeds (F1)

F1 hybrid seeds are the garden’s high achievers — created by crossing two specially chosen parent plants for superior vigor, uniformity, and performance. We use only traditional breeding methods to produce these powerhouse seeds.

Open-Pollinated & Heirloom Seeds

Our open-pollinated (OP) seeds naturally reproduce through wind, insects, water, or self-pollination. When grown in isolation, they produce true-to-type plants year after year.

Among our OP seeds are treasured heirloom varieties — old favorites that have been carefully passed down for generations. While OP plants can be less uniform than hybrids, we run our Open-Pollinated Project to select the most reliable, flavorful, and beautiful strains. Many are also available as certified organic seeds.

Non-GMO: What It Means and Why It Matters

GMO (Genetically Modified Organism) is created when scientists alter a plant’s DNA in a lab — often by inserting genes from completely unrelated species — to achieve certain traits, like pest resistance or herbicide tolerance. This is a far cry from natural plant breeding.

At Shido, we believe gardening should stay as close to nature as possible. All our seeds — whether hybrid, heirloom, organic, or open-pollinated — are Non-GMO. They’re bred using traditional methods that respect natural biodiversity, giving you safe, wholesome seeds that grow into plants just as nature intended.

When you plant Shido Non-GMO seeds, you’re choosing purity, sustainability, and peace of mind — along with a garden full of flavor, color, and beauty.
