MILDEW ON ROSES. 



Can you help us out of the problem of 

 mildew on roses? We have had mildew 

 constantly for two months. We paint 

 half the hot water feed pipes with sul- 

 phur and water three times a week and 

 we have tried the patent mildew ma- 

 chines, with but little effect. We run the 

 night temperature from 55 to 60 degrees, 

 and the day temperature from 75 to 80 

 degrees. We syringe on all bright days. 

 The varieties are Bride, Maid, Eichmond 

 and Chatenay. J, T. 



Mildew at this season should not be 

 seen in a greenhouse, as it is easy to keep 

 it from germinating. 



No amount of sulphuring will subdue 

 mildew if conditions are maintained 

 which are favorable to the germination of 

 the spores and their subsequent growth. 

 Keep the temperature at 56 to 58 degrees 

 at night, with air on if possible. Keep 

 the atmosphere as dry as can be done 

 with safety to the plants. The minimum 

 day temperature should be 60 degrees; 

 the maximum, 75 degrees. Mix the sul- 

 phur with air-slaked lime in the propor- 

 tion of one part of lime to two of sul- 

 phur. Make it of the consistency of 

 paint and apply twice a week. 



In addition, use the Peerless sulphur 

 blower once a week. Select a bright day 

 for this and close the ventilatora when 

 applying, allowing the temperature to run 

 up to 90 degrees for a short time. Mil- 

 dew cannot possibly exist under these 

 conditions. Bibes. 



OLD RICHMOND ROSE PLANTS. 



Will you please tell us the best method 

 of making old Richmond roses, that have 

 been carried over two or three years, 

 break strong canes from the baset Our 

 Bichmonds seem to be growing a lot of 

 small top flowers, and are not breaking 

 as they should. A. G. L. 



Had this correspondent given isome in- 

 formation regarding the treatalent his 

 roses have been receiving, with a state- 

 ment as to whether they are on table or 

 solid benches, I would be in a better posi- 

 tion to advise him. 



By bending the old branches to a right 

 angle about six inches above the ground 

 and tying them to keep them in place, the 

 dormant eyes at the base of the stem 

 would be encouraged to break. As soon 

 as these break, give the beds a light 

 mulch of rich material, such as one part 

 cow manure and two parts rich loam, or 

 one part pulverized sheep manure and 



three parts loam, with a sprinkling of 

 bone added in each case. 



Give the beds a thorough soaking. 

 Keep the night temperature at 58 de- 

 grees, with the day temperature at a 

 minimum of 65 degrees and a maximum 

 of 75 degrees. Feed with liquid manure 

 once a week after the eyes break.

HILL'S NEW ROSE. 



The latest American rose to attract at- 

 tention in Europe is another of the novel- 

 ties of the E. G. Hill Co. The name is 

 Panama. This novelty is not claimed to 

 be a forcer, but is lauded as an outdoor 

 variety. Last January plants were sent 

 for trial in the Jardin Bagatelle, Paris, 

 where the variety Rhea Reid made so fine 

 a showing when these trials were insti- 

 tuted. Panama was second in the Baga- 

 telle trials of this year, falling only one 

 point behind the variety Arthur Goodwin, 

 in spite of the late start the plants had. 

 European observers say it will stand high 

 in the list next year, after the plants 

 have become thoroughly established. 



GRUBWORMS IN ROSE BENCHES. 



Can you give us a remedy for grub- 

 worms in rose benches! The worms are 

 about an inch and a half long and an 

 inch in circumference. They work all 

 through the soil, making it very loose, 

 and as a consequence the roses are drop- 

 ping their foliage. We have tried lime 

 water and other things, but without any 

 good results. T. L. M. 



These grubworms are hard to exter- 

 minate after they have got into a bench. 



Sometimes, for want of their natural 

 food, grass roots, they are quite de- 

 structive to young rose plants. 



The most effectual method of getting 

 rid of them is by digging them up and 

 hand picking. As they are larvae, they 

 will not increase in numbers and so they 

 can, with patience and perseverance, be 

 finally cleaned out. They can be killed 

 by using the bisulphide of carbon in 

 strong doses, but as this is an explosive, 

 it might result in doing more damage 

 than even the grubs will do. Bibes. 



RAMBLERS MAKE POOR GROVTH. 



Under separate cover I send you two 

 cuttings from my hardy Crimson Ram- 

 bler rose bushes. I should like to know 

 the trouble with theni, as they have not 

 done well since I planted them out. I 

 have them on the south side of my house, 

 in a sunny place, E. T. 0. 



Each of the samples received would 

 indicate that your plants are making a 

 feeble growth. The most likely cause for 

 this is poverty of the soil. Ramblers of 

 all kinds make vigorous growth if given 

 good soil to grow in. Another point to 

 remember with ramblers is to entirely 

 cut out each season the wood which has 

 flowered and depend upon the shoots 

 which start from the bottom for the suc- 

 ceeding year's flowering. You do not 

 state whether or not your plants are in 

 grass. If so, they will not grow nearly 

 so satisfactorily as when the soil can be 

 cultivated about them. If the shoots 

 fairly indicate the strength of your 

 plants, I would advise you to start with 

 fresh plants, either now or in early 

 spring, and if you afford them a liberal 

 root run in good soil, they can hardly 

 fail to make strong growths. C. W. 



BOLIVAE, N. Y. — A. C. Bickerson, of 

 Bradford, N. Y., has purchased three 

 acres of land on North Main street and 

 will erect three greenhouses, each 20x100 

 feet. 



HoLDREGE, Neb. — The Davidson Floral 

 Co. has nearly completed its new green- 

 house, 39x100, and is putting in all solid 

 beds of concrete. There was a gain of 

 about thirty per cent in the Thanksgiving 

 business, as compared with a year ago, 

 and the indications are good for the com- 

 ing year.
