Asgrow Seeds are Well-bred 
LETTUCE 
Lettuce does not stand hot weather ivell 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 deep in the open then. Rich and well-prepared soil 
is advisable as the plants must be groivn quickly. Moisture and thorough cultivation are also 
required. Allow ^-oz. per 100 ft. of row; 3 lb. per acre.
