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.
