Asgrow Seeds are Well-bred 
LETTUCE 
Lettuce does not stand hot weather well but is not harmed by mild frosts; the earliest sorts can 
therefore be transplanted from cold frames to the rows, after hardening by gradual exposure, in the 
first weeks of spring and the later sorts sown x /±' deep in the open then. Rich and well-prepared soil 
is advisable as the plants must be grown quickly. Moisture and thorough cultivation are also 
required. Allow V2-0Z. per 100 ft. of row; 3 lb. per acre.
