The Weekly Florists' Review* 



JANUABT 25, 1906. 



Cannas are started iuto growth from 

 the first to the end of March. If you 

 would prefer them in flower by the end 

 of May, then start operations early in 

 March. Spread one inch of sphagnum 

 moss (cocoanut fiber will do just as 

 well) on a bench in a house where the 

 night temperature is about 60 degrees. 

 Put the roots on the material quite 

 thickly. Then cover the roots thinly with 

 the same material. If you have heating 

 pipes beneath the bench, none the worse. 

 Keep the moss or fiber slightly moist. 

 In two or three weeks the roots will 

 begin to start their leaf growth, as well 

 as make working roots. When three or 

 four inches above the moss lift them 

 out and put into 4-inch pots with a, well 

 manured compost and keep on a light, 

 warm bench. There is nothing more to 



be done, except give ordinary daily care. 

 We have often received canna plants 

 from very large firms that had evidently 

 been reared in a shady, warm house and 

 they were soft and sloppy, but we did 

 not kick, for we know how much the 

 headpiece of this firm had to think of 

 and it was superhuman to expect that 

 lie could spread himself over acres. 



The canna is a native of the torrid 

 zone and enjoys our hottest weather, and 

 if not neglected for water when their 

 avaricious roots are crowded into a 4- 

 inch pot, will endure our brightest suns 

 under glass. Don't expect all these roots 

 to start at once with the same strength 

 and vigor, but all that are sound will 

 start within six weeks and you will not 

 have wasted space, pots or soil.

BEST SIX ROSES. 



Will you kindly tell me what six named 

 varieties of roses are best for greenhouse 

 culture? I would like colors red, pink, 

 white and yellow, and what time should 

 they be set in the greenhouse to bring 

 them into bloom for the holidays? 



E. V. M. 



The best roses to grow under glass are 

 those Avhich are most in demand and 

 for a beginner easiest of culture. In 

 whites. Brides and Ivory stand at the 

 top. In pinks. Bridesmaids, Chatenay 

 and Killarney. In reds. Liberty and 

 Richmond. In yellows, Perle des Jardins 

 and Franz Deegan, Ivory, Chatenay and 

 Richmond, not being quite so susceptible 

 to mildew and other troubles, and being 

 good doers, are the varieties best suited 

 for a beginner. Golden Gate is also a 

 good and profitable rose. The usual time 

 to bench roses is late in May or early in 

 June, which gives them a sufficient 

 length of growing season to produce a 

 good crop in September and still another 

 at holidav times. Ribes. 



INFESTED WITH EEL WORMS. 



I am sending you a root of a rose 

 plant and should be glad to have you 

 state if they are aifected with club root 

 or eel worms. E. C. 



The specimen plant is badly infested 

 with eel worms, which have undoubtedly 

 caused this form of club root. Under a 

 powerful magnifier these small tubercles 

 will be found to contain from three to 

 five and frequently more small worms al- 

 most invisible to the naked eye and which 

 resemble eels in, appearance. These 

 worms by encysting themselves in the 



small feeding roots cause the tubercle 

 to form. These tubercles are constantly 

 increasing in size and becoming more 

 numerous, sapping the vitality of the 

 plants and destroying root action. 



Like all low forms of animal life these 

 nematodes are very retentive of life and 

 hard to destroy. As yet I have learned 

 of no means of destroying them without 

 also destroying the plant host. They 

 perish in solutions of acids and of most 

 metallic compounds, but, unfortunately, 

 these are also destructive of vegetable 

 life. 



If the rest of the stock is as badly in- 

 fested as the specimen sent they should 

 be thrown out without delay, as recovery 

 according to our present knowledge is out 

 of the question. It would also be very 

 unsafe to propagate from such stock, as 

 they are so reduced in vitality that the 

 young plants wouid become an easy prey 

 to the same trouble. Ribes.

FORCED CIRCULATION OF.WATER. 



[A paper by H. S. Dodson, read before the 

 Detroit Florists' Club, January 3, 1906.] 



The forced circulation consists of the 

 ordinary hot-water system in connection 

 with a pump. The ordinary hot-water 

 system is based entirely upon gravity as 

 the force which circulates the water in 

 the system, and by reason of the hot 

 water being the lighter, it is forced up- 

 ward by the descending cold water, but the 

 difference in the weight is not great 

 enough to insure rapid circulation. In 

 order that the returning water be suffi- 

 cient to cause a reasonably rapid circu- 

 lation, the temperature must fall from 50 

 to 80 degrees. 



In using the gravity system for heat- 

 ing on a large scale it is readily seen 

 that this drop in the temperature of the 

 water is something to be avoided as the 

 heat emitted from water at this greatly 

 reduced temperature has little heating 

 value.
