or even less. "When placed in a cold storage house, they 

 can be kept for a year. Unlike other bulbs that are 

 forced, they do not require to form roots before being 

 brought into heat. 



THE TUBEROSE. 



The tuberose, some ten years ago, was extensively 

 forced, but it receives little attention to-day for winter 

 blooming. For spring flowering, the first lot may be 

 placed in four-inch pots soon after Christmas, and 

 plunged in damp sphagnum or sand, in a forcing house, 

 where they will have a bottom heat of eighty degrees. 

 A succession can be secured by starting others at inter- 

 vals of three weeks. If designed for flowering in the 

 fall, the bulbs should be kept in a cool place, where 

 they will be moist enough not to dry out, until August, 

 when the first batch can be started, and with a second 

 a few weeks later, flowers can be obtained from Novem- 

 ber until January. 



call A. 



The calla is one of the easiest flowers to force, and 

 it can generally be used to good advantage. The bulbs 

 should be potted in August, having first rubbed off all 

 suckers, and after receiving a good watering should be 

 kept for a month in some cool place, where they will not 

 be allowed to dry out. It requires a richer soil than 

 most bulbs and delights in an abundance of water. A 

 seven-inch pot will answer for a large bulb, and if a 

 larger pot or tub is used, there should be several bulbs 

 placed in it. As soon as the season of growth is over, 

 the pots should be placed on their sides, and kept in a 

 cool, airy place, without water, for several months. 

 Unlike the hyacinths and narcissus, the calla can be 

 grown for several years without renewing the stock, 

 although many florists prefer to purchase each year
