Leeks (Allium ampeloprasum var. porrum) are a hardy, cool-season vegetable from the onion family, valued for their mild, sweet onion-like flavor. Unlike onions, leeks do not form bulbs; instead, they produce long, white stems with dark green leaves. They are commonly used in soups, stews, and various culinary dishes, offering a subtle yet flavorful taste. Leeks are easy to grow and can thrive in a home garden or container, making them a popular choice for both beginners and experienced gardeners.

How to Plant Leek from Seed

Preparing for Planting

  1. Choose a sunny location with well-draining soil.
  2. Loosen the soil to at least 12 inches deep.
  3. Add compost or organic matter to improve fertility.

Sowing Seeds Indoors

  1. Fill seed trays or small pots with seed-starting mix.
  2. Sow seeds ¼ inch deep, spacing them ½ inch apart.
  3. Keep the soil moist but not soggy.
  4. Place in a warm area with temperatures around 65-70°F.
  5. Expect germination in 7-14 days.

Direct Sowing Outdoors

  1. Sow seeds ¼ inch deep in rows 12 inches apart.
  2. Thin seedlings to 4-6 inches apart once they reach 3 inches tall.
  3. Continue hilling soil around the stems to blanch them.

Transplanting Seedlings Outdoors

  1. Once seedlings reach 6-8 inches tall, harden them off by gradually exposing them to outdoor conditions.
  2. Dig trenches 6 inches deep and space rows 12-18 inches apart.
  3. Plant seedlings 3-4 inches apart, burying them up to the base of their leaves.
  4. Gradually fill in the trench as the leeks grow to encourage long, white stems.

Pro Tip

For long, tender leeks, practice blanching by mounding soil around the stems as they grow—this keeps them pale and mild in flavor. Plant them in deep trenches and keep the soil consistently moist.

Bonus: A light frost improves their sweetness!

Getting to know your Leek

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.
