Lettuce Germination Information

Lettuce Seed Germination How to Sow Lettuce:

  • Best sown outdoors
  • It is a cool season crop that should be sown as soon as the soil can be worked in early spring or in late summer for a fall crop.
  • In Zones 8 and warmer, seeds may be sown in early fall for winter crops
  • Make successive sowings for as long as the temperature is below 80°
  • Seeds can also be sown indoors, 4 weeks before planting out, at a temperature of 65-68°
  • Indoors and out, sow with no cover as light aids in germination and expect germination in 7-10 days
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Lettuce:
Transplanting: Transplant when there are at least two sets of true leaves, doing so very carefully so as to avoid inducing shock.

Spacing: Space leaf types 4-6 inches apart and head types 10-12 inches apart. Plant both in rows spaced 12-18 inches apart

Soil: Site in full sun in a neutral, light, rich, moist, well-drained soil. Keep well watered and feed lightly every 3-4 weeks

Appearance and Use:

There are four basic types: Crisphead (not grown in home gardens, rather a product of mass production for grocery stores) forms a round, firm, tight ball. Butterhead forms a more open head of crisp, fleshy leaves. Romaine forms a tall, slender, open, vase-shaped head that is taller than wide. Leaf lettuce types form round, loose, rosettes of leaves. Harvest the heading types when the center is firm; harvest the outer leaves of the leaf types first, then harvest the entire head when it is mature
