How Transplanting Improves a 

 Plant 



IT HAD long been a common practice among plant 

 growers to prick out young seedlings into flats 

 when they were from two to three weeks old and 

 possibly again about three weeks later before they 

 were set in the field. Some of the gardeners about 

 the city, who made it a business of growing cabbage, 

 tomato and celery plants for sale, claimed that 

 those plants which 

 had been trans- 

 planted once or 

 twice before setting 

 were much better 

 plants and, as it took 

 more labor to handle 

 them in this way, 

 they demanded $2 

 to $3 per thousand 

 for them. Other 

 gardeners claimed 

 that there was noth- 

 ing in it and grew 

 their young plants 

 entirely where the 

 seed was sown and 

 so were able to re- 

 alize a good profit 

 by selling at from $1 

 to $1.50 per thou- 

 sand. 



This caused a con- 

 siderable amount of 



discussion. Neither side had any actual data to 

 prove its beliefs in regard to the matter and, since it 

 was of far more importance to the growers of these 

 various crops, I decided last season to carry out a 

 test to determine the effect of each of these 

 methods of starting young tomato plants upon the 

 earliness of bearing and the yielding powers. The 

 variety grown was Greater Baltimore. 



The plants were started in a hotbed and handled 

 as indicated in the following table:

Those in plot No. 1 were left in the hotbed where 

 they were sown 

 until they were 

 set in the field. 

 Those in plots 

 2 and 3 were 

 t ransplanted 

 into gardeners' 

 flats and placed 

 back in the bed 

 for a week and 

 then put in

 Here they were 

 hardened off

 tirely removing 

 the sash. The
