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 
ps 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 V 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 season 
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 cultivation. A side dressing of 
nitrate of soda, given as soon as the plants have made some growth, will 
be found beneficial.
