Red Iceberg Lettuce Conventional & Organic

Red Iceberg Lettuce Conventional & Organic

LT428

50 days. A colorful alternative to the rather ordinary green iceberg types. This attractive red, almost chocolate-colored iceberg borrows the eye-catching qualities of a red looseleaf to form a spectacular lettuce. The medium-sized heads are fairly tight and hold a long time before going to seed. Nice mild flavor.

Days to maturity are calculated from date of direct seeding.

Culture
• Lettuce performs best in cool weather, 60-70°F, and grows in a wide range of soil types
• Plant as early as soil can be worked
• For extended harvest, plant every 2-3 weeks and choose heat tolerant varieties for summer
• Lettuce seed can be sown every month from February—October
• A cold frame and cold-hardy varieties can stretch the spring and fall growing season into the winter months
• Apply 1 cup of TSC's Complete fertilizer per 10 row feet, and 1 inch of compost
• 1 gram of seed will sow 30 row feet
• Consistent, even watering is critical for best results

Direct Sowing
• Use row cover to improve germination and prevent soil crusting
• As soon as 2-3 true leaves have formed, thin loose-leaf types to 10-14 inches apart; icebergs, butterheads, and romaines to 12-16 inches apart

Transplanting
• Start indoors 4-6 weeks before anticipated transplant date

Insects & Diseases
Common pests: Aphids and slugs
Pest control: Strong spray of water for aphids or applications of Pyrethrin or Neem oil, baits, traps, or Cabbage Collars for slugs

Harvest & Storage
• While picking individual leaves helps extend the season somewhat, all eventually become bitter as they begin to bolt

What is pelleted seed?
Seed that has been coated with a clay-based material to form a larger, round shape. This makes planting by hand or mechanical seeder easier and allows for more controlled sowing of small seeds such as carrots or lettuce. All pelleted seed has a National Organic Program (NOP) approved coating.
