How to Plant Green Leaf Lettuce from Seed

When to Plant Seeds

  • Spring planting: Sow seeds 2-4 weeks before the last frost date.
  • Fall planting: Sow seeds in late summer, about 8 weeks before the first frost.
  • Can also be grown indoors year-round in containers.

Preparing for Planting

  1. Choose a sunny location with well-draining, fertile soil.
  2. Loosen the soil to a depth of 6-8 inches.
  3. Mix in organic compost or aged manure for added nutrients.

Sowing Seeds

  • Scatter seeds ¼ inch deep in rows 12 inches apart.
  • Lightly cover with soil and water gently.

Thinning Seedlings

  • Thin seedlings to 6-8 inches apart once they sprout.
  • For continuous harvests, succession plant every 2 weeks.

Pro Tip

For crisp and flavorful green leaf lettuce, plant in cool weather and provide consistent moisture to prevent bitterness. Use rich, well-draining soil and space plants 8–10 inches apart for good airflow. Harvest outer leaves frequently to encourage continuous growth, or cut the entire plant just above the base for regrowth.

Bonus: To extend the harvest, plant in succession every 2–3 weeks and provide light shade in hot weather to prevent bolting.

Getting to know your Green Leaf Lettuce

Green Leaf Lettuce is a cool-season, loose-leaf variety with vibrant, tender, ruffled leaves. It grows best in moist, nutrient-rich soil with ample sunlight and moderate temperatures. Unlike head-forming lettuces, green leaf lettuce does not develop a compact core, making it easy to harvest continuously by picking outer leaves. It requires consistent watering to maintain crisp texture and prevent bitterness. The plant grows 6 to 12 inches tall and is ideal for succession planting. Green leaf lettuce is widely used in fresh salads and sandwiches due to its mild, slightly sweet flavor and crisp texture. It is susceptible to pests like aphids and slugs, but row covers and companion planting help protect it.

What it's used for

1. Culinary Uses:

  • Commonly used in salads, wraps, sandwiches, and burgers.
  • Can be used as a garnish or in smoothies for extra nutrition.
  • Pairs well with a variety of dressings and toppings.

2. Companion Planting:

  • Grows well with carrots, radishes, onions, and cucumbers.
  • Avoid planting near brassicas like cabbage, which can compete for nutrients.

3. Soil Improvement:

  • Acts as a great cover crop to help reduce soil erosion.
  • Enhances soil fertility when composted after harvest.
Growth Requirements

Light:

  • Prefers full sun to partial shade.
  • In hot climates, partial shade helps prevent bolting (premature flowering).

Soil:

  • Requires well-draining, loamy soil with a pH of 6.0-7.0.
  • Adding compost or organic matter improves nutrient content and moisture retention.

Watering:

  • Needs consistent moisture, about 1-2 inches of water per week.
  • Avoid overwatering to prevent root rot and fungal diseases.

Temperature & Climate:

  • Thrives in temperatures between 55-70°F (13-21°C).
  • Bolts quickly in high temperatures above 75°F (24°C).

Fertilization:

  • Benefits from light applications of balanced fertilizer (10-10-10).
  • Too much nitrogen can lead to excessive leaf growth but poor flavor.
Maintenance

Watering:

  • Keep soil evenly moist, but avoid overwatering.
  • Use mulch to retain moisture and suppress weeds.

Weed Control:

  • Hand-pull weeds carefully to avoid disturbing the shallow roots.
  • Apply a layer of organic mulch to prevent weeds from growing.

Harvesting and Seed Collection

1. When to Harvest:

  • Ready for harvest in 30-50 days after planting.
  • Pick outer leaves first for a continuous harvest.
  • Harvest entire plants before bolting for the best flavor.

2. Collecting Seeds for Future Planting:

  • Allow some plants to bolt and produce yellow flowers.
  • Collect dry seed heads and store seeds in a cool, dry place.
Pests and Diseases
  • Common Pests: Aphids, slugs, and leaf miners.
    Use floating row covers or companion planting (e.g., marigolds) to deter pests.
  • Common Diseases: Downy mildew and rot.
    Improve air circulation and avoid overhead watering.

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

A 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.

Vacuum-Sealed for Freshness — Good for 10 Years

Every Shido seed packet is vacuum-sealed to lock in freshness and protect your seeds from moisture, air, and pests. This careful packaging not only preserves their quality but also extends their shelf life dramatically. Stored properly in a cool, dry place, our seeds remain viable for up to 10 years — so you can plant them now, next season, or even years down the road. Whether you’re planning a garden this spring or building a long-term seed stash, Shido seeds are ready when you are.
