An Old World crop, appreciated since ancient times, that requires cooler temperatures to grow really well. Sow in place in the garden as early in spring as soil may be worked— seeds sprout and grow whenever mild weather predominates. Or start indoors and set out acclimated seedlings 2-4 weeks before last frost date. Succession plant lettuce for a continual crop, but avoid long days and heat of early-mid summer. May be grown right through the winter where the weather is mild, or under row cover, cold frames, etc. Lettuce is healthy and rich in Vitamins A & C. — http://www.rareseeds.com/store/vegetables/lettuce/

Lettuce is a cool-weather crop that thrives in the temperature range 60-65 degrees F, and if thoroughly hardened, most varieties survive temperatures as low as 20 degrees F. Cold-adapted varieties survive much lower temperatures. Seed germinates best at about 75 degrees F. Lettuce seed will germinate at a temperature as low as 40 degrees F. Early spring plantings should be made as hardened transplants from seed started one month before setting outdoors. Later plantings can be direct-seeded. Sow seed 1/4" deep and thin to 10-16" apart depending on the variety. Loose-leaf varieties may be planted more closely but good air circulation should be maintained around the plants. Soil should be cool and moist during the germination period.

Germination Notes: If the temperature exceeds 80 degrees F lettuce will often fail to germinate. Lettuce can be planted during late summer or early fall while the days are still hot provided that the seeds are germinated in the refrigerator for 4-6 days. Another method is to soak seed in 10% bleach for 2 hours at 40-60 degrees F followed by 4 water rinses. This method enhances both the speed and amount of germination. One more method is to keep soil cool with burlap or boards; remove cover promptly after germination to keep grasshoppers and other pests from enjoying the shaded tender sprouts!

Bolt Resistance: Resistance to bolting is highest with loose-leaf lettuce, followed in order by romaine, butterhead, and bibb, and crisphead. Lettuce bolts more readily if exposed to temperatures below 50 degrees F during the 2- to 3-leaf stage (the first three weeks after germination). Thus, spring lettuce is best started indoors and transplanted out at least 3 weeks after sowing. Before the days become hot, mulch the plants to keep the root temperature cool.

Extend your harvest into early summer with this technique: plant tall vegetables in north-south rows and plant heat-resistant lettuce underneath the leaf canopy so that it is shaded during the hottest portion of the day. Corn planted in rows 4 feet apart or pole beans on a fence or trellis is ideal. Interplanting lettuce with bush squash also gives good results. Mulch the lettuce well, keep well watered and enjoy!

Harvest and Flavor Notes: The glucose content of lettuce harvested in the morning may be 2-1/2 times greater than lettuce harvested in the early afternoon. For best quality and maximum sweetness harvest by 7-8 am, especially in summer.

Greenhouse Note: Use heat-tolerant, loose leaf or bibb types.

Insect Pests and Diseases: In the greenhouse, control aphids by means of ladybugs, sticky yellow traps or by insecticidal soap. Maintain good air circulation around plants to reduce disease.

Maturity Dates: Dates are from direct seeding. Subtract 15-20 days for dates from transplanting.

Seed Savers: Isolate varieties by a minimum of 12' for home use. For pure seed isolate varieties a minimum of 25-50'.



Romaine (Cos) Lettuce
Romaine lettuce produces upright, elongated tall heads with thick succulent ribs and distinctively flavored long thick crinkled leaves. Moderately tolerant of heat and shade, romaine does best in a loose fertile soil, and is the most nutritious type of lettuce. Buttercos lettuce has the characteristics of both butterhead and cos.
