70 COMMERCIAL ROSE CULTURE 



suits from leaving plants thirty inches high and just as good 

 when they were cut down to within ten inches of the ground. 

 Some growers object to cutting down Killarney. We have 

 had good results in almost every style and would cut back hard 

 any time before the middle of August. After Sept. 1st we 

 would not cut back very much. Some growers tie 

 down their old plants, others prefer to leave them 

 standing upright. There is little difference in the re- 

 sult, perhaps a greater tendency to black spot where tied down 

 as the air cannot circulate through the bushes so well in this 

 case. As a rule the earlier it is in the season the harder we 

 cut them. 



As soon as pruned we scrape off the top loose soil, sprinkle 

 with bonemeal, and then apply a good coat of loam and cow 

 manure in equal parts, about two inches thick. The beds are 

 then well watered ; this is best done by going over them two or 

 three times, as soon as the covering is on and then repeating the 

 operation the next day. After they are once soaked, no more 

 water at the roots is required for some time, but the tops will 

 require syringing several times daily to induce the plants to 

 make a new growth. As they grow they will require the usual 

 treatment. It is well, when replanting in the Summer, to pot 

 up a few of the best plants before throwing out stock from 

 benches. These will be found useful to fill in any vacant space 

 or to replace poorer plants among the stock carried over. 



The best night temperature for the general run of Roses is 

 58 to 60. Some varieties require more heat, but, as a rule, 

 these are not profitable kinds for the small grower to handle. 

 The heat should rise to 70 or 75 at noon on every sunny 

 day in the Winter. On stormy, zero days, it will sometimes 

 be impossible, nor is it desirable to increase the temperature 

 more than a few degrees by noon, and in semi-dark weather 

 68 at noon gives the best results in the long run.
