Latuca sativa

Culture

Lettuce is cool season annual in the Compositae family, which includes endive, escarole, chicory, globe artichoke, sunflower, Jerusalem artichoke, salsify, and burdock.

  • Looseleaf- var.crispa.  First to maturity, these fast growing lettuces do not form a head.  Good for babyleaf culture.
  • Butterhead - also known as bib, or Boston, this type forms a loose head with slightly oily leaves. Beautiful, sweet and tender, but bruises and tears easily.
  • Romaine – var.longfolia.  Romaine forms a tall dense upright head with a tender heart. It tolerates warm temperatures and is less prone to bolting.
  • Iceberg – var. capitata.  The fussiest type to grow, iceberg will form a compact round head if given a long cool season. It bolts easily if stressed.

Soil Nutrients and Requirements

Choose cool, well drained, loose soil with pH 6.2-6.8. Lettuce is sensitive to low pH.  Use 50-75lbs Nitrogen/acre, ~150 Phosphorus and Potassium/acre. Sidedress with N 3-4 weeks after planting. With transplanting, use 2lbs/50 gallons starter fertilizer, 4-8oz per plant

Plant Spacing

Mini: 6"

Row Spacing

12-18” or 3 rows/36” bed, 5’ centers.

Harvest

Cut lettuce holds best when harvested in the morning and cooled rapidly.  For salad mix or baby leaf production, harvest individual leaves when they reach desired size, or cut evenly across the bed making sure to stay above the growing tip.  For a continuous harvest, sow lettuce every 3 weeks.

Storage

Store just above freezing temperatures with 98% humidity.

Pest Info

  • Tarnished Plant Bugs cause brown scarring on stems. Romaine is especially susceptible.
  • Cabbage looper and cutworms can be controlled by Bacillus thuringiensis (such as Dipel DF, see Supplies) and/or spinosad (such as Entrust™), preferentially in rotation with one another to prevent selection of resistant individuals (check with your certifier before applying).
  • Leafminers burrow underneath the skin and leave weaving, translucent trails. They are usually controlled by natural enemies.
  • Slugs and Snails can be baited by beer traps. Practice clean cultivation and avoid mulch.

Disease Info

Many lettuce diseases are best prevented by production practices that maximize airflow around heads to stimulate rapid drying. Many varieties have been bred to have disease resistance.
