Growing Tips & Guides

Get Started

Lactuca sativa

Days to maturity are calculated from date of direct seeding.

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

Culture
• 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
• 1 gram of seed will sow 30 row feet
