If desired, lettuce may be planted several weeks in ad- 
vance of tomatoes and the plants cut and sold at a sacrifice 
when the tomatoes must be set in the permanent beds. 
Planting distances, time of planting and size of plants 
vary greatly in the management of different commercial 
establishments.

It is an advantage to plant the lettuce several weeks in 
advance of the cucumbers, and to sell the small plants 
and replant the spaces with large cucumber plants. In 
some instances growers plant small cucumber plants, but 
small plants are usually injured by the crowding of the 
lettuce. :
