The Weekly Florists^ Review* 



SUFTHMBBB 17, 1908. 



TEMPERATURE. 



At what temperature should Killarney, 

 Eichmond and Enchantress be kept? 



E. P. L. 



The best night temperature for these 

 varieties is from 56 to 58 degrees, with 

 ventilation whenever it is possible. 



BiBES. 



ROSE LEAF BLIGHT. 



There seems to be some trouble with 

 some of our roses, the Eichmond, Kil- 

 larney, Brides and Maids. The Golden 

 Gate in the same house do not show it. 

 We had it last year in winter and now 

 we see it on young stock that has been 

 growing most thriftily so far. It is not 

 black spot, but it might be called brown 

 spot. It shows on the young, tender 

 shoots and, by the time the bud has 

 developed, the leaves below show big 

 brown spots, or some of them dry up or 

 fall oif entirely, or sometimes the bud 

 and top wither, as if for lack of water. 

 A leaf at first shows a darkish spot, usu- 

 ally toward the tip and from the upper 

 side, but in time the substance of the 

 spot is gone, leaving a dead looking place 

 on the leaf, if it does not spread to the 

 entire leaf. 



We enclose some leaves, but are afraid 

 they will not be in condition to show the 

 trouble. I shall be most grateful if you 

 can name the trouble and cause, and any 

 remedy or treatment. Z. K. J. 



The leaves were somewhat shriveled 

 when they reached nie, but they fur- 

 nished sufficient evidence to show the 

 effects of some fungous trouble. The 

 fungus appears to be the rose leaf blight, 

 which, if unchecked, will cause a lot of 

 troublo in a short time. It may not be 

 this identical fungus, but it would be 

 safe to treat it as such. 



Spray with the carbonate of copper 

 compound, using five ounces of carbonate 

 of copper to three quarts of ammonia 

 and sixteen gallons of water. Spray 

 once a week, using a nozzle that makes a 

 fine spray, and wet every part of the 

 leaves. This is a sovereign remedy for 

 many of the fungi which trouble the 

 rose under glass. Eibes. 



A SLOW START. 



We are mailing yon under separate 

 cover a rose plant and sample of the soil 

 the stock is growing in. They do not 

 seem to be doing as well as we think 

 they ought to, and would like to trouble 



you for a little help if you can give us 

 any, as to how we shall proceed to better 

 their conditions. 



The soil was taken from a pasture lot 

 that had not been plowed for twenty- 

 three years, the sod being plowed under 

 in March and replowed in Aprit About 

 the middle of May we hauled it near the 

 greenhouses and piled it up and mixed in 

 about one-fourth of cow manure. The 

 plants were si^all 2^4 -inch stock and were 

 planted on the benches June 25. The 

 black soil jrt^ will find is the soil they 

 were in when we got them from Chicago. 

 About ten days after planting we gave 

 them a sprinkling of lime and raked it 

 in, and in about three weeks we raked 

 in a sprinkling of bone meal. They 

 have had plenty of ventilation and have 

 not been overwatered. For the last three 

 weeks we have watered them once a week 

 with nitrate of soda, using a 4-inch 

 potful to fifty gallons of water. Are we 

 light in doing this? The varieties are 

 Bride, Maid, Eichmond, and Uncle John. 

 The Bride and Maid are doing better 

 than the others, but have not made the 

 growth we think they should. I have 

 been growing plants all my life, under 

 glass and outside, but this is my first at- 

 tempt at roses under glass, so anything 

 you can tell us to do to make these roses 

 grow will be greatly appreciated. 



S. F. P. 



to try to force growth on such young 

 stock by the use of nitrates. The black 

 prairie soil in which the young plants 

 were originally potted, although present- 

 ing a poor appearance, has nothing to do 

 with the present condition of the plants, 

 as it is capable of producing high-grade 

 stock. 



Cultivate freely, at least once a week, 

 to the depth of an inch; keep the plants 

 tied up ; give plenty of water ; night tem- 

 perature 56 to 58 degrees; day tempera- 

 ture 75 to 80 degrees, always with venti- 

 lation whenever possible ; keep the syringe 

 going to keep down spider and produce a 

 humidity in the atmosphere. 



As the stock is suffering from no dis- 

 ease, they will soon outgrow the present 

 weakness. Ribes. 



PLANTS FOR FLORISTS' GROUNDS 



The Irises. 



The soil, though a little deficient in 

 fiber, is excellent for rose culture and 

 the proportion of cow manure is right. 

 The sprinkling of bone meal would also 

 l)e beneficial. It is, however, a mistake 



Those florists who have home grounds 

 are missing an opportunity if they do 

 not plant a bed of irises. Such a one 

 as shown in the accompanying illustra- 

 tion, even if it be not so large, will, 

 when in bloom in spring, be the means 

 of bringing a good number of orders 

 for similar planting. 



Too many people still think of the 

 iris as the old blue flag of the fields 

 and do not appreciate the beauty of the 

 modern iris. The accompanying illus- 

 tration is from a border of German 

 irises in the garden of Z. G. Simmons, 

 at Kenosha, Wis., where John H. Wil- 

 cott is gardenei'. This is an ideal spot 

 for the iris, as it faces the east and is 

 backed by a hedge of mulberry trees, 

 which were planted for the purpose of 

 screening the neighboring back yards , 

 from the view. The hedge also serves 

 the purpose of keeping the ground moist 

 and breaking the strength of the after- 

 noon sun. This gives a splendid border 

 effect the entire length of the garden 

 and is also ornamental in spring, before 

 the garden is all planted. The soil is a 

 rich, sandy loam and the irises are 

 planted in large clumps. Mr. Wilcott 

 spreads plenty of manure on the ground 

 early in the spring and, if suflicient rain 

 does not fall, he gives the ground a good
