Lettuce 'Rosenkrantz'
Lettuce 'Rosenkrantz'
Lactuca Sativa
A more compact and refined crisphead with dark red blush and red splashes that blanch a tightly folded whorl of a head. Chefs LOVED this lettuce for her flavour, “sweet, crunchy, with mineral undertones that are delightful”, unique appearance, ease of washing and the way the leaves hold the dressing. This Frank Morton introduction has great downy mildew resistance even under strong disease pressure. Unique shade of red as a baby leaf.

TRANSPLANT - Sow indoors early Spring, 2 seeds per cell, barely covering seeds with fine vermiculite, 3–4 weeks before transplanting outdoors. Thin to 1 plant/cell. Shade the flats on sunny, warm days if necessary to keep the soil surface cool, below 24°C, until germination. Harden seedlings by reducing water and temperature for 2-3 days before planting outdoors. Properly hardened transplants can survive temperatures as low as 0°C.
DIRECT SOW - Lettuce is hardy and can be planted as early as the soil can be worked. It is a cool weather crop and grows best at temperatures of 16-18°C. Seeds germinate even at low, 4°C, soil temperature, but poorly above 24°C. Sow seeds 2.5cm apart in rows 25-30cm apart. Lightly cover and keep moist. Enjoy thinnings ultimately leaving 25cm between plants. Ample water grows the sweetest lettuce. Careful variety selection is important for hot weather plantings. Sow every 3 weeks for a continuous supply of fresh lettuce.
