Planting 



As soon as the plants are roceivcd it is best to 

 immediately plant, yet if it is impossible to do this 

 the plant should be placed in a cellar or moderately 

 warm place and protected from the sun. Set them 

 ' upright to admit the free circulation of air. When 

 I you receive them they will be wrapped in Sphagiuim 

 ! Moss, which should be removed before plant inji, as 

 j it is used only foi- pi-otection. Water fie(^ly fioni time 

 to time. The I'oots should be coveied with soil or 

 [ burlap and never allowed to become dry. Soaking 

 I the roots in lukewarm water or thin mud for an hour 

 or two before planting to restore their vitality is 

 ; beneficial. Do not set the plants too shallow. They 

 j should be planted deeper than they were glowing in 

 I the pots before shipping. This can easily be de- 

 termined by an examination of the plant. If you le- 

 ceive them with the soil on the roots in which they 

 have been growing, do not remove this soil. Give 

 them as near a natural position as possible. Use 

 plenty of water after planting and shade for a few 

 ! Jays, if the sun is hot, with newspaper or similar 

 I material, and if the season is a dry one an occasional 

 i watering will be beneficial. The best time to plant 

 Roses such as we send out, being pot-grown, own 

 : root stock, is in early spring. This refers entirely to 

 pot-grown plants and not dormant plants. By dor- 

 I mant plants we mean field-grown ; that is, lifted from 

 I the field and have not made any growth whatever. 

 ; Such plants as these should be set out earlier than 

 i pot-grown plants. Instructions for planting dormant 

 [)lants sent with each order of such. 



Cultivation 



Cultivate top soil about 2 inches deep every week 



M after every hard rain. Do not cultivate when w^et. 



; This may be discontinued after the blooms come, 



I when a good mulching of Peat Moss, cow manure, 



I tobacco stems, buckwheat hulls, are left aro\md the 



bushes the balance of the season. In dry weather 



water throughly at least once a week, and in the 



morning. 



Pruning 

 As soon as the winter covering is removed, first 

 •ut away all weak stems and leave three or four of 

 the strongest. Prune these down to at least six inches 

 high with the Hybrid Teas. Hybrid Perpetuals or 

 the June Roses do not need as close pruning. Bushes 

 that are 2 to 4 feet in height should be cut back 

 I bout 1-2 or 2-3 of their growth. The Polyantha and 

 Baby Ramblers need just the tips cut. Climbing 

 Roses should be pruned after blooming, cutting out 

 dl shoots and allow the new ones to develop and to 

 train. Keep all weak lower side stems cut away 

 throughout the season. When several buds appear 

 Dn one stem the smaller buds may be pinched ofT to 

 make one fine large rose. 



Winter Protection 



The protection needed varies according to the 

 •limate and varieties of roses. After a few hard frosts 

 lave stopped the growth throw up a mound of earth 

 I bout a foot high around the plant. In cold sections 

 ifter the ground has frozen put straw or other coarse 

 itter in between the mounds built up around each 

 )lant. The tops of the bushes sticking out above 

 nounds may be covered with evergreen boughs. Do 

 lot remove this covering until spring has come to 

 j 5tay and remove gradually. 



Selection of Roses Important 



One of the most diflfi(!ult pr()l)lems that presents 

 itself to the amateur about to start a rose garden, 

 is the very first that he has to solve, the selection 

 of the best varieties of roses for the purpose foi' 

 which he intends them. The success he will have 

 with his roses depends very laigely on intelligent 

 selection of adaptable vaiietic^s. ^I'lie rnattei' of selec- 

 tion is one that should be left to the i)urchaser. 

 Many of our customers gi'ow 100 or more difTei-ent 

 kinds and they find exquisite beauty in each. At the 

 modest price asked for them any one can enjoy 

 many sorts. 



Dwarf Baby Ramblers 



These are a type of Polyantha Rose but more 

 dwarf in habit, 12 to 18 inches. Hardy and suitable 

 for beds or borders along walks, etc. Small blooms 

 in immense clusters. Always blooming. Thost^ offered 

 in catalog are the standard sorts, all good. 



Climbing or Rambling Roses 



The climbers are not so susceptible to mildew and 

 disease as the Ramblers, therefore much to be pre- 

 ferred. Some of the Hardy Chmbers resemble the 

 Ramblers so closely that any one wanting them will 

 find a great improvement in such Climbers as Ex- 

 celsa, Tausendschon and Aunt Harriet. 



Chmbing Roses should all have some support such 

 as a pergola or arch. A wire fence, where convenient, 

 may be utilized with splendid effect. They also make 

 a good hedge. 



For pillars, roses like Paul's Scarlet, Birdie Blye, 

 Dr. Huey, Mary Lovett, Chmbing American Beauty 

 are good. They may also be used as individual speci- 

 mens by pruning to a shape and size desired. 



Insects and Diseases 



For insects and diseases of all kiuds we recommend 



TRI-OGEN 



Combined Spray Treatment 



Fungicide — I nsecticide — Plant Stimulant 



Complete Protection against Plant 

 Insects and Diseases 



In the past. Mildew and Black Spot have been most 

 difficult to combat. However, these diseases are now 

 easily controlled with the Tri-ogen Spray Treatment, 

 which gives COMPLETE protection against all diseases 

 and insect pests. It is easily applied and also acts as 

 a plant stimulant — producing vigor in growth with 

 resultant luxurious blooms, heretofore considered im- 

 possible. The Tri-ogen Spray Treatment applied weekly, 

 from early season until late frost, makes it possible 

 for the amateur to achieve the success, in many cases, 

 comparable to the professional grower. 



TRI-OGEN was officially adopted for the exclusive 

 protection of the Garden of 6000 Roses, at the 

 CENTURY OF PROGRESS, Chicago World's Fair.
