Essential Growing Requirements

☀️

Sunlight

4-6 hours of sun daily. Morning sun with afternoon shade in hot climates. Can tolerate partial shade.

🌱

Soil

Rich, well-draining potting mix. Keep soil consistently moist but not waterlogged. pH 6.0-7.0.

💧

Water

Keep soil evenly moist. Water when top inch feels dry. Use room temperature water to avoid shocking roots.

🌡️

Temperature

60-75°F (15-24°C) ideal. Bolts (goes to seed) in hot weather. Protect from frost below 45°F (7°C).

Planting & Care Guide

Sowing and Planting

Starting from Seed

Lettuce seeds are easy to start indoors or direct sow outdoors.

  • Indoor starting: 4-6 weeks before last frost
  • Direct sowing: When soil temperature reaches 40°F (4°C)
  • Seed depth: 1/4 inch deep, press firmly
  • Spacing: 4-6 inches between plants

Succession Planting

Plant new seeds every 2 weeks for continuous harvests throughout the season.

  • Small batches: Plant 4-6 seeds per container every 2 weeks
  • Variety mix: Combine different lettuce types
  • Season extension: Use cold frames or row covers
  • Space efficiency: Replant harvested areas immediately

Ongoing Care

Watering Technique

Consistent moisture prevents bolting and bitter leaves.

  • Frequency: When top inch of soil feels dry
  • Method: Gentle soaking, avoid overhead watering
  • Morning watering: Allows leaves to dry quickly
  • Mulching: Helps retain soil moisture

Fertilization

Light feeding supports steady growth without excess nitrogen.

  • Balanced fertilizer: Diluted half-strength every 2-3 weeks
  • Organic options: Compost tea or fish emulsion
  • Avoid excess nitrogen: Can cause bitter leaves
  • Soil amendment: Mix compost into potting soil

Harvesting Your Greens

✂️

Cut-and-Come-Again

Harvest outer leaves while leaving inner leaves to continue growing. This method provides multiple harvests from one planting.

Best for:

Loose-leaf varieties, arugula, spinach, kale

🌱

Baby Leaf Harvest

Pick young, tender leaves when they're 3-4 inches long. This produces the most delicate flavor and texture.

Best for:

Mixed salads, sandwiches, garnishes

🥬

Full Head Harvest

Wait for head formation and harvest the entire plant. Cut at soil level for crisp, formed heads.

Best for:

Romaine, butterhead, iceberg varieties

Pro Harvesting Tips

Timing Matters

  • • Harvest in the morning when leaves are crispest
  • • Pick before plants bolt (flower) in hot weather
  • • Regular harvesting encourages more growth
  • • Remove any yellowing or damaged leaves

Storage & Use

  • • Wash gently and spin dry immediately
  • • Store in damp paper towels in refrigerator
  • • Use within 5-7 days for best quality
  • • Add to salads, sandwiches, smoothies, or cooking

Common Lettuce Problems

Bolting (Flowering)

Plants suddenly produce tall flower stalks and bitter leaves, usually triggered by heat or stress.

Prevention:
  • • Plant heat-tolerant varieties
  • • Provide afternoon shade in hot climates
  • • Maintain consistent moisture
  • • Harvest regularly to reduce stress

Bitter Leaves

Leaves develop bitter taste due to stress, heat, or over-maturity.

Solutions:
  • • Harvest younger leaves (3-4 inches)
  • • Pick in the morning when sugars are highest
  • • Ensure adequate but not excessive water
  • • Protect from extreme temperature swings

Slugs and Snails

Common pests that leave irregular holes in leaves, especially in moist conditions.

Control methods:
  • • Hand-pick pests at night with flashlight
  • • Use copper tape around containers
  • • Apply diatomaceous earth around plants
  • • Reduce moisture on leaves

Tip Burn

Brown, crispy edges on leaves caused by calcium deficiency or inconsistent watering.

Prevention:
  • • Maintain consistent soil moisture
  • • Use balanced fertilizer with calcium
  • • Avoid wide temperature fluctuations
  • • Ensure proper soil pH (6.0-7.0)
