FORCING LETTUCE IN POTS. 



Sc^^ 



HE following description of a method of forciug lettuce in pots 

 that has been followed at the New York Agricultural Experiment 

 Station, may be of interest to those who grow lettuce under glass^ 

 either in an amateur way or as a commercial product. 



The seed is sown in flats as usual, that is to say in boxes 

 about twelve by ten inches and three inches deep. When the 

 plants are about two inches high they are transplanted to two inch 

 pots. The benches are filled with soil, in which the pots containing the lettuce 

 are plunged so that the top of the pots are covered with about half an inch of 

 soil. 



Preparation of Soil. 



Soil for lettuce should not be too heavy, and as the soil which we use for 

 potting is a rather heavy clay loam, sand is mixed with it in preparing it for the 

 lettuce house. The potting is composed of three parts by measure of loam, one 

 of manure and one of sand. 



The benches are six inches deep ; the lower three inches being filled with 

 well-rotted manure, and see upper three inches with potting soil prepared as 

 described above.
