REPEATED ATTACKS OF MILDEW. 



I slioulil like to ask your roso expert's 

 opinion conce.iiiug a house ^OxoO, heated 

 by liot water and planted with about 

 500 roses. The stock inohules Killar- 

 ney, Bride, Bridesmaid, Richmond, Sun- 

 burst and Mrs. A. Ward — a much too 

 promiscuous lot to do well. Last De- 

 cember I found that these were infested 

 with red spider, which I got under con- 

 trol only by constant work. Ever since 

 the firing season commenced, the roses 

 have been subject to repeated attacks 

 of mildew. The night temperature has 

 been steady at from 56 to 60 degrees, 

 with careful watering and ventilation 

 throughout the season. 



The house runs east and west and has 

 a brick wall on the north side. The roses 

 are on raised benches and are planted 

 in good clay loam, with about one-fourth 

 cow manure. I did not plant these 

 roses, but for the repeated attacks of 

 mildew I am inclined to blame the drain- 

 age, as I find the bottom of the benches 

 lined with a thick clay sod. This, in 

 my opinion, causes too much humidity, 

 and all the pipe-sulphuring in the world 

 has no effect on the mildew. The only 

 rose which seems to escape the attacks 

 is Mrs. "Ward. The stock is 2 and 3 

 years old. What is the best course to 

 adopt? Would it be best to throw the 

 whole lot on the dump and restock next 

 July? I only want roses from October 

 till May and would let the plants rest 

 in June and July. When I first took 

 charge of the house, I found the stock 

 in the condition which I have described.

As the jdants are in bad shape now and 

 there are toe many varieties to permit 

 the cutting of a fair number of any one 

 sort, it would no doubt be more profit- 

 able in the long run to throw out the 

 lot, clean out the benches, see that there 

 is good drainage in the bottom — about 

 a half-inch to a three-quarter inch space 

 between the boards if the benches are 

 wooden — and replant with young stock 

 as soon as possible, so as to give the 

 plants plenty of time to make good 

 growth by the time you want to start 

 cutting. Plant not more than one va- 

 riety of each color, say Killarney for 

 pink. White Killarney for white, Rich- 

 mond or Milady for red and Ward or 

 Sunburst for yellow. Give these va- 

 rieties a temperature not lower than 60 

 degrees at night. If Wards are to be 

 planted, put them at the warmer end of 

 the house. 



If the plants are kept at the tempera- 

 ture mentioned, with plenty of ventila- 



tion at all times and enough feed to keep 

 them in good growing condition, they 

 should he good, large plants by October 

 and there will be little danger of mildew 

 )is long as the pipes are occasionally 

 painted with sulphur. Good clay loam, 

 witii one-fourth cow manure and a good 

 sprinkling of bone meal, is as good a 

 soil as you can get for roses.

IS THERE ENOUGH HEAD ROOM? 



I have a greenhouse which is four 

 feet high to the eaves, eleven feet high 

 to the ridge and twenty-four feet wide, 

 standing east and west. Could I grow 

 good roses in such a house or would the 

 exposed glass in the roof be too near 

 the plants? I should like to grow Killar- 

 neys and Richmonds, or would some 

 other varieties be better to grow in 

 such a house? Any advice that can be 



given will be greatly appreciated by 

 such a beginner as I. I am located ic 

 Indiana. H. M. 



A house such as described would 

 grow fairly good roses, provided it is 

 kept at the right temperature. If 

 the roses are planted in solid beds they 

 will have suflSicient head room, but on 

 raised benches there would hardly be 

 enough head room to allow either Rich- 

 mond or Killarney to be grown as they 

 are generally grown now in up-to-date 

 places, except, perhaps, in the center 

 benches. The Wards, however, would 

 do better, being low growers. The 

 nearness of the glass to the plants 

 would not do any harm, so long as the 

 flowers do not touch the glass in win- 

 ter, in which case they would freeze. 



The best temperature at night for 

 Killarney is 60 degrees. Richmond 

 will give satisfactory results in a tem- 

 perature 2 degrees lower, and Ward in 

 a temperature 2 to 4 degrees higher. 

 If there is a market for Wards in your 

 locality and the right temperature can 

 be kept up, it would probably be the 

 most profitable rose to grow in the 

 house. W. J. Keimel. 



GOOD YELLOW ROSES. 



I want to plant 500 yellow roses. 

 Which of the many new yellow varieties 

 would be the most profitable for a small 

 place? J. A. & S. 



For quantity I would recommend Mrs. 

 Aaron Ward; for quality, Sunburst.

PREPARATIONS PROGRESSING. 



The Minneapolis florists are a fore- 

 handed lot, who do not believe in the 

 modern maxim, "Never do today what 

 can be imt off until tomorrow." They 

 are so far along with their convention 

 preparations that it seems as though 

 hardly anything can remain to be done. 

 Though the convention was uninvited, 

 Minneapolis florists most certainly have 

 taken great pride in its coming. They 

 have enlisted the Minneapolis Civic and 

 Commerce Association and the conven- 

 tion is being exploited both at home 

 and abroad in a fashion never before 

 attempted. The Civic and Commerce 

 Association has a publicity bureau 

 which is grinding out reams of copy, 

 li any editor is short of material, just 

 let him let the fact be known and the 

 void will be filled by Minneapolis. If 

 one is not interested in the school en- 

 rollment, or the manufactures per cap- 

 ita, he can learn of the train service 

 on the nine trunk lines between Chicago 

 and the metropolis of the northwest, or 

 he can learn in picture or prose of the 

 beauties, of the Minneapolis park sys- 

 tem, or of the five large new hotels. 



one of which is said to have cost more 

 to build, per square foot, than any other 

 hotel in the country. 



But while the Civic and Commerce 

 Association is trying to impress the 

 trade with the advantages of Minne- 

 apolis, it is not failing to tell the people 

 of Minneapolis of the coming of a dif- 

 ferent type of convention from the 

 ordinary. Minneapolis newspapers are 

 being used to tell the people there of 

 the advantages to the city in having a 

 visit from the national organization of 

 florists. The chairmali of the associa- 

 tion 's committee on conventions has 

 told the people that the S. A. F. meeting 

 will be of more value to Minneapolis 

 than a score of other gatherings. 



In preparation for. the convention a 

 committee of the association is urging 

 Minneapolis business men to display 

 even more generously than in other 

 years the window boxes and hanging 

 baskets in the downtown section which 

 in other years have won distinction 

 throughout the country as the hanging 

 gardens of Minneapolis. It is stated 

 that the planting of vacant lots and 

 home gardens has this year exceeded
