group being rarely so. These, like those of the Rambler class, require 

 a season of preparation before reaching the useful flowering stage, though 

 in a lesser degree than the Ramblers. In a few instances, and where 

 the plants are of good size and well rooted, the maidens may be per- 

 mitted to flower in the spring following the potting up, though the 

 quality of the flower in no sense compares with that afforded by the 

 more-established example. 



POTTING UP MAIDENS. There is no time in the year to equal the 

 first half of October for potting up all maiden plants from the open 

 ground. At the time stated the new root fibres are most active, and 

 the plants quickly take to the fresh soil. Even where the plants cannot 

 be immediately potted it were better to lift them and heel them in, so 

 that the formation of the new root fibres is retarded. 



Hybrid Perpetuals are best potted annually at about the same period, 

 whilst Teas and Hybrid Teas, being more continuous in shoot and root 

 production, and being required for autumn and winter work, should be 

 repotted or topdressed as required in August or September. Good loam, 

 with well-decayed horse dung and a little blood and bone manure, is all 

 that the Rose requires. Highly concentrated manures in the hands of 

 the inexperienced may be a source of considerable danger, and are not 

 to be trifled with. 



TEMPERATURES AND MILDEW. These are not infrequently first cousins. 

 Aided by the constant use of the syringe and the stuffiness of the 

 houses mildew will spread like wild-fire. A drier overhead method of 

 treatment, freer ventilation, the abolition of the syringe, and, finally, 

 little or no mildew. For early winter forcing, start the plants in a 

 temperature of 45 F. and increase to 55 F. for Hybrid Perpetuals and 

 to 60 F. for Hybrid Teas about six weeks later. 



LONG-STEMMED ROSES. Pot-grown Roses for market represent but 

 one phase of the subject, and thousands of long- stemmed Roses result 

 from planted-out specimens. These, however, cannot be started into 

 growth so early as pot-grown plants, and are best when given a much 

 slower treatment from the start. This applies to the Hybrid Perpetual 

 class more particularly, and always to those in beds at ground level, as 

 opposed to those on raised beds or benches receiving the benefits of the 

 applied heat. 



POPULAR VARIETIES. Were I asked to name the most popular of 

 market Roses I should say, without hesitation, Madame Abel Chatenay, 

 in addition to which one might take Niphetos, The Bride, Bridesmaid, 

 Catherine Mermet, Sunrise, Liberty, and Richmond. Of late the apricot- 

 yellow Lady Hillingdon has appeared upon the scene and it is simply 

 ideal for early work. The Hybrid Perpetuals would, of course, include 

 Captain Hayward and that lovely old and fragrant rose, General 

 Jacqueminot. A set of varieties indispensable for long stems should 

 include Joseph Lowe, Frau Karl Druschki, Captain Hayward, Mrs. 

 J. Laing, and Ulrich Brunner. [E. H. j.]
