WINTERING AND PROPAGATING 55 



blooming kinds. In February or March the 

 tuber is planted in sand and sunk in a warm 

 tank. Soon it sends out a host of shoots. 

 These mature one by one. They may be 

 broken off and potted separately as soon as 

 they have one or two floating leaves. Each 

 tuber, therefore, of the night blooming water- 

 lilies will produce enough plants to stock a 

 large pond. It is a wise precaution to keep 

 one or two plants in small pots all summer, 

 just to form tubers. The old plants some- 

 times rot completely when taken in. 



Tender nymphaeas that are to be carried 

 over the winter for another season must be 

 taken up before there is a chance of a killing 

 frost, that is between October 15th and 30th. 

 If possible, drain the pond of enough water to 

 facilitate the work, removing the leaves from 

 the plants and cutting off the roots about 

 a foot from the centre. Then take up the 

 plants with as much soil as will cling to them. 



The best winter quarters for the tender 

 nymphaeas is under the bench of a greenhouse 

 with a temperature of from 60° to 65° F.
