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 in the open then. Rich and well prepared soil is ad- 
visable as the plants must be grown quickly. Moisture and thorough cultivation are also required.
