are kept cut off and the plants pruned in to induce 

 new shoots being thro^^-n out, which produces the 

 flowers. The average planter is extremely timid in 

 pruning because he is afraid of the injury- it will 

 possibly do. This idea should be discarded, because, 

 as we have said, the priming of all Roses is bene- 

 ficial. 



The different varieties of Roses differ very much 

 in habit of growth; many are neat and compact, 

 requiring little or no trinmning, while others of the 

 same class are A-igorous and straggling, sending 

 out long shoots which tend to outrun the limits 

 assigned them. Pruning, therefore, is a matter to 

 be governed by the judgraent of the possessor of 

 the plants. We will add, however, that plants of 

 persistent growth should be 

 trimmed back each fall or in 

 early spring about one -half to 

 two -thirds of the season's 

 growth. Where plants, appar- 

 ently healthy, fail to mature the 

 buds which they bear, remove 

 a large percentage of the unde- 

 veloped buds and imperfect 

 blooms and prune severely. 

 Also trim back about one-third, 

 when, after planting, they shed 

 their leaves and exhibit signs of 

 weakness; this gives the roots 

 a chance to become \'igorous. 



INSECTS AND INSEC- 

 TICIDES 



HEALTHY, ^'igorous Roses 

 are less liable to the rav- 

 ages of insects than weak 

 specimens which do not have 

 the \'itality to resist the on- 

 slaughts of the pernicious para- 

 sites. Our Roses are singularly 

 free from insects, owing to their 

 \'igor, but, should they become 

 infested, a few applications of 

 a good insecticide will extermi- 

 nate them at the outset, after 

 which ver\' little or no trouble 

 will be experienced. One of the 

 most common of insects is the 

 green-fly, wliich •will be found 

 usually on Roses of weak 

 growth. We, at times, find them 

 attacking our Roses, but they 

 are readily removed by s}Ting- 

 ing with clear water or smoking 

 with tobacco stems; but where 

 these accessories are not to be 

 had, we recommend kerosene 

 emulsion or tobacco insecticide 

 soap, which, when applied with 

 a TjTian Sprinkler, ■^\-ill usually 

 destroy them effectually. 



The red spider is an insect so 

 small that it is not discernible 

 to the naked eye, infesting the 



underside of the foliage, and turning it, as a rule, an 

 unhealthy copperv- red color. Where the plant is in 

 \'igorous gro-«^h, this insect is not to be found to any 

 appreciable extent, except on the old fohage, 

 which can be removed, but, should it attack the 

 growing foliage, frequent syringing with the insec- 

 ticides named above, should be restored to. The 

 rose hoppers or thrips are not so prevalent, and a 

 syringing ^\-ill effectually exterminate the Rose- 

 hopper, while the leaf rollers, which resemble 

 butterflies, of yellowish white color, roll themselves 

 up in the leaves of the Roses, and can be picked 

 off by hand. The Rose bug, common in some locali- 

 ties and which appears during the early growing 

 season, is one of the most pernicious insects and 



can be removed only by \'igilant and unceasing 

 syringing with in.secticidea. 



Rose grubs, which live in the ground, where they 

 hatch out innumerable offspring, are found only 

 in some localities, but they are very destructive, 

 feeding on the roots of the Rose, and before one 

 knows that the plant has been destroyed they 

 have accomplished their work. The only remedy 

 is to dig into the ground and destroy them. If the 

 soil is continuously affected with them, a good coat- 

 ing of air-slaked lime spaded in well will prove 

 helpful. We receive quite a few complaints of the 

 foliage of Roses being covered -with a white flour- 

 like substance, and asking for a remedy. This is 

 mildew, which some varieties are subject to, 



Dingee Roses in the garden. Tree Rose, Madame CaroUne Testout, 

 see page 1 of circular and page 35 of this book, in the foreground 



notably Crimson Rambler after it has finished its 

 period of bloom. Mildew does not seriously damage, 

 but makes the plant unsightly. The remedy is to 

 dust the foliage in the morning while the dew is yet 

 upon it with flowers of sulphur, which may be had 

 at almost any grocery or drug store. A few appli- 

 cations will suffice to kill the mildew effectually. The 

 following receipts and preparations are good. They 

 should be applied both to the upper and the under- 

 surface of the foliage by means of a good sprinkler. 

 We can supply the Tyrian Plant Sprinkler, the 

 Auto-Spray and New Era Sprayer, at prices given 

 elsewhere in this book. All of these are inexpensiv* 

 and very satisfactory and will add much to the joy 

 of growing healthy Roses.
