LETTUCE - BLACK SEEDED SIMPSON

  Organic Lettuce Black Seeded Simpson

        150 Seeds Pack    

Black Seeded Simpson lettuce is a classic variety that has been cultivated for over 150 years. Known for its resilience, it is more heat-tolerant than many other lettuces, although it will bolt in hot summer conditions, producing a tall central stalk with yellow flowers. This hardy variety can also withstand light frosts and mild drought. A fast-growing lettuce, Black Seeded Simpson can be harvested for baby greens as early as three weeks after planting. Suitable for cultivation nine months out of the year, it produces beautiful light green heads with firm, crinkly leaves.  

    PLANTING & GROWING

Lettuce is a versatile and easy-to-grow crop that thrives in containers or garden beds. It can be grown in plant containers on a balcony or indoors near a sunny window. Use a pot that’s at least 20cm (8 inch) wide with drainage holes to ensure proper growth, as lettuce has sensitive roots and does not respond well to repotting. 

If starting seeds indoors, disinfect all pots, trays, seed cells, and covers to prevent damping off.

Lettuce tolerates a wide range of soils but grows best in well-drained, cool, loose soil with plenty of moisture and a pH between 6.2 and 6.8. If the pH is too low, add lime to raise it to at least 6.0. Seeds germinate in 7 to 14 days, with optimal germination temperatures of 4 to 16°C (40 to 60°F); rates decrease above 20°C (68°F). Ideal growth occurs between 16 and 18°C (60 to 65°F).

Lettuce can be sown almost year-round. Start seeds under protection from February to March and transplant outdoors in April, or sow directly outdoors from March to August. For overwintering, sow in early autumn. For the best harvests, sow in succession every 14 days from spring to mid-summer. Butterhead varieties mature in about 72 days and are more drought-tolerant than most salad greens.

To plant, sow seeds at a depth of 6 to 12 mm (¼ to ½ inch) in rows spaced 30 cm (12 inches) apart. Create shallow trenches with a cane, spacing rows about 20 cm (8 inches) apart. When seedlings reach 2 cm (1 inch) tall, thin them to 15 to 20 cm (6 to 8 inches) apart to allow proper growth. The lettuce flower, called a capitulum, is hermaphroditic and self-pollinating, but cross-pollination by insects can occur, especially in hot climates.

Lettuce pairs well with root crops like radish, carrot, parsnip, and beets, as well as taller plants, aromatic herbs, and alliums (onions, leeks, garlic). Alliums also repel caterpillar pests attracted to leafy greens. In fall, planting lettuce alongside root or allium crops can help maintain healthy greens through winter.

Avoid planting lettuce near cabbage, kale, broccoli, Brussels sprouts, cauliflower and mustards, as they are incompatible companions.

Avoid planting lettuce in the same location for consecutive growing seasons.
