The Florists' Review 



n 



COVERED WITH BED SPIDEB. 



Enclosed you will find two rose plants 

 that have some kind of root disease. I 

 shall be thankful if you can tell me 

 what is wrong with them and what I 

 can do to remedy the trouble. I have 

 handled roses for several years, but 

 have never seen the roots act in this 

 way before. The soil that I used was 

 new soil, with a little rotted cow ma- 

 nure in it. The plants are in a good 

 house, with a temperature of 60 degrees. 



C. K. 



The two plants received were care- 

 fully examined and, as far as I could 

 see, there was absolutely nothing the 

 matter with the roots; they were as 

 healthy as they could be for plants of 

 that size, from 2-inch pots. One of the 

 stems had been bruised when the cut- 

 ting was made and the surface had 

 turned black, but this would not affect 

 the growth. The other plant was green 

 to the roots and the roots were perfect. 



There was one serious defect in the 

 condition of the plants and this, no 

 doubt, was the cause of the whole 

 trouble; the plants were completely cov- 

 ered with red spider. They were so 

 badly injured by this pest that even 

 the youngest leaf had started to turn 

 gray. It will take a continuous appli- 

 cation of water under high pressure, for 

 some time, to get the plants clean again, 

 but if this is done I can see no reason 

 why the plants should not make a good, 

 healthy growth. As long as the spider 

 sucks the sap out of the plants, how- 

 ever, they cannot make much growth.

EXPEBIMENTAIi ROSE GARDENS. 



The American Eose Society, through 

 its committee in conjunction with a 

 committee appointed by the Society of 

 American Florists, now feels ready to 

 launch the establishment of two experi- 

 mental rose gardens, one in connec- 

 tion with the Department of Agricul- 

 ture at Washington, D. C, and one at 

 the College of Agriculture, Cornell 

 University, Ithaca, N. Y., and in this 

 connection they ask the cooperation of 

 rose growers throughout America. 



Appended to this invitation will be 

 found statements from both these in- 

 stitutions, indicating their readiness to 

 proceed with this proposition. 



It is proposed that credit shall be 

 given in each garden to all firms con- 

 tributing to its success, but it is not 

 proposed to make public any statement 

 showing which varieties were contrib- 



uted by any firm. In this way it is 

 hoped that all rose growers in America 

 may be placed on the same footing, 

 without favoritism being shown to any- 

 one or any group of growers. 



Rose growers everywhere will be 

 quick to see the advantages likely to 

 spring from these experimental gar- 

 dens. We are fortunate to have one 

 in a district representative of the 

 colder sections, while results in the 

 other may be taken as a criterion for 

 the warmer sections of our country. 



We are fortunate in each case to have 

 the backing of institutional care that 

 shall be impartial in its cooperation 

 and insure the continuity of effort so 

 essential to an enterprise in which real 

 success can be measured only after a 

 term of years. Furthermore, both in- 

 stitutions are in position to issue bul- 

 letins, and, for the benefit of all con- 

 cerned, spread dependable information 

 regarding roses. 



Therefore, the American Rose Soci- 

 ety and the Society of American Flo- 

 rists, through their committees, hereby 

 appeal to the rose growers of America 

 for (Contributions of all such varieties 

 as they are willing to present for these 

 two gardens. The committee asks that 

 each firm furnish a list of such varie- 

 ties as can be supplied this spring, such 

 list to be in the hands of Alex. Gum- 

 ming, Jr., chairman of the Eose So- 

 ciety's committee, not later than March 

 15. The committee requires good, strong 



dormant stock where available, other- 

 wise stock well established in not less 

 than 4-irch pots. Dormant stock must 

 be in Washington not later than April 

 1, and at Ithaca April 15; roses from 

 pots, not later than May 1 at Wash- 

 ington, May 15 at Cornell. There will 

 be required eighteen (18) each of the 

 bedding types of roses, including the 

 HjpP. 's, P. 's, H. T. 's, bourbons, Chinas, 

 polyanthas, etc., and of the rugosas, 

 sweet briars, or any of the climbing 

 types, five (5) each. 



Delivery instructions will be issued 

 later. It is the earnest desire of the 

 committee, if possible, to have every 

 firm of rose growers in America repre- 

 sented by plants in these gardens.

FROM U. S. DEPARTMENT OF AGRICULTURE. 

 Bureau of Plant Industry. 



Washington, D. C, Feb. 14, 1914. 



With further reference to the letter of the act- 

 ing secretary to your committee, addressed to 

 W. F. Gude, under date of August 16, 1913, the 

 ground proposed to be devoted to a rose garden at 

 Arlington Farm In conjunction with your societies 

 is now available for that purpose and the Bureau 

 of Plant Industry stands ready to push the work 

 of planting as soon as the stock arrives and the 

 weather Is suitable. 



The objects to be gained from the Department's 

 standpoint are the possibility of researches in the 

 heredity of cultivated roses, and also the adapt- 

 ability of roses to climatic conditions similar to 

 those of Washington.

 Assistant Chief of Bureau. 



FROM NEW YORK COLLEGE OF AGRICULTURE. 



Department of Floriculture. 



Ithaca, N. Y., Feb. 19, 1914. 

 The rose garden area on the grounds of the 

 department of floriculture at Cornell is in excel- 

 lent condition to receive the plants this spring. 

 The department has the facilities to properly care 

 for the stock immediately upon arrival ' and to 

 plant as soon as weather conditions permit. The 

 undersigned will give bis personal attention to 

 the details of the rose trials. An investigation 

 of the botany, evolution, breeding, etc., of the 

 hybrid, Wlchuraiana and rambler roses is already 

 in progress. It is proposed to make similar 

 studies as to the adaptability of all classes of 

 roses suitable to the climate of central New 

 York. Particular attention will be given hybrid 

 perpetuals, hybrid teas, polyanthas, rugosas and 

 the hardy climbing types.

MUMS TO FOLLOW TOMATOES. 



Will you kindly inform me what are 

 the best chrysanthemums for late flow- 

 ering and by what date they ought to 

 be put in the greenhouse beds or 

 benches? We wish to use our beds for 

 a second crop of tomatoes and then to 

 follow these with mums for the first 

 winter crop, so that early mums would 

 probably be out of the question. I am 

 located in southern Ontario. 



R. N. W. 



Late mums can be planted on the 

 benches as late as August 1, if one can 

 prQpagate nice, soft young plants so 

 late in the season. The middle of July 

 would possibly be better. By this time 

 the spring crop of tomatoes should be 

 out of the way, or the price, owing to 

 the outside plants coming into crop, 

 would be cut down below a lucrative 



figure. I know florists who are making 

 good use of their houses by running a 

 spring crop of tomatoes, getting them 

 out of the way by July and then plant- 

 ing with mums to follow. It is not 

 necessarily implied that R. N. W. has 

 to plant the latest varieties for this pur- 

 pose, as the plants can be carried along 

 to 4-inch pots and planted from these, 

 or could even be planted outdoors, 

 lifted carefully and transplanted into 

 the house. There are many ways of 

 economizing on greenhouse space when 

 one has to do it. 



A good list of late varieties is as fol- 

 lows: White — Thanksgiving Queen, 

 Timothy Eaton, White Chadwick and 

 Jeanne Nonin. Yellow — Nagoya, Yel- 

 low Chadwick and Bonnaffon. Pink — 

 Chadwick Supreme, Maud Dean and W. 

 R. Brock. These varieties will give 

 flowers until Thanksgiving and some 

 of them, like Brock, till Christmas. The
