Growing Lettuce The most favorable conditions for growing good 
lettuce are rich soil, plenty of moisture and 
steady growth from the time the seeds are 
planted until ready for use. Seed germinates quickly and may be 
planted as soon as the cold wet days of spring are past. Sow in 18 
inch rows, 15 to 18 inches apart to a depth of not more than y 2 inch. 
Loose Leaved Varieties may be thinned to about 1 inch apart as 
soon as a few leaves are formed. When large enough for eating, they 
may be thinned further as used. 
When growing Head Lettuce it is necessary that the heading sea¬ 
son take place during cool weather. For this reason, it is a good 
policy to sow the seed in boxes indoors or in hotbeds and set out as 
early as weather conditions permit. If this is not practical, seed may 
be sown in the open ground as early as soil and weather conditions are 
favorable. Thin 10 inches apart in the row and give thorough cultiva¬ 
tion. A side dressing of nitrate of soda given as soon as the plants 
have made some growth will be found beneficial.
