Growing Tips

  • Sow seeds directly outdoors during cool weather.

  • Make successive sowings every few weeks during suitable weather for continued harvests.
  • Provide afternoon shade in warmer climates to help reduce heat stress.

Seed Storage

Store unused seeds in a cool, dry, dark location. Keep them sealed in their original packet or an airtight container away from moisture, heat, and direct sunlight.

Unique Facts About Seeds

  • Purple lettuce belongs to the Asteraceae family, which includes sunflowers and daisies.
  • Purple and burgundy lettuce leaves get their distinctive color from naturally occurring plant pigments.
  • Lettuce is a cool-season crop that generally performs best in mild temperatures.
  • Lettuce seeds are tiny and should be planted shallowly rather than deeply buried.

Growing Instructions

Planting Season: Sow seeds during the cooler parts of the growing season. In mild climates, lettuce can be grown during fall, winter, and early spring.

Sowing: Prepare loose, fine soil and scatter seeds evenly over the surface. Cover lightly with fine soil or seed-starting mix.

Depth: Plant approximately ⅛ inch deep.

Spacing: Thin seedlings to approximately 6–12 inches apart depending on the variety and desired harvest size.

Sunlight: Provide full sun to partial shade. In warm climates, afternoon shade can help extend the growing season.

Soil: Use fertile, loose, well-drained soil enriched with organic matter.

Watering: Keep soil consistently moist but not waterlogged. Regular moisture supports tender leaf growth.

Germination: Seeds commonly germinate within approximately 2–10 days under favorable conditions.

Thinning: Thin crowded seedlings after they develop their first true leaves. Young thinnings can be used as salad greens.

Fertilizing: Add compost or a balanced vegetable fertilizer if needed. Avoid excessive fertilizer.

Care: Keep weeds controlled and monitor plants regularly. Mulching can help maintain consistent soil moisture.

Flowering/Maturity: Lettuce develops leafy growth before producing a flowering stalk when exposed to heat or allowed to mature. Harvest before significant bolting for tender leaves.

Harvesting: Pick outer leaves as needed or harvest the entire plant once it reaches the desired size. Harvest in the morning for crisp, fresh leaves.
