COLE CROP PROJECTS 



95 



seedlings should be ready to be transplanted in three or four weeks. 

 This will allow six weeks more before they will be wanted for field 

 planting. In the warmer parts of the North, as in New Jersey, the 

 plants may be set with safety in the open ground about April 1. 



Fig. 26. — Flat of seedlings; onions, lettuce, and cabbage plants. 



In this case the seed should be sown January 15. There should 

 be about ten weeks from seed sowing to field planting. 



The cabbage requires a lower temperature for starting the plants 

 than the tomato. A day temperature of 60 degrees and 50 or 

 even 45 at night will be found suitable for growing good plants. 

 Further instructions in W : 51 and references will be found applica- 

 ble to sowing seed for the early crop.
