GREEN FLY AND MILDEW. 



I have a house in roses, such as 

 Maryland, Bride and Maid. I planted 

 them July 18 and they did finely un- 

 til a few days ago, when the leaves 

 began to turn yellow and fall off: They 

 are suffering from both green fly and 

 mildew. 1 have smoked them with to- 

 bacco stems twice a week, but the 

 pests are still on the plants. Will you 

 kindly let me know what to do to get 

 rid of them? I have been firing at 

 night and maintaining a temperature 

 of 65 degrees at night and SO degrees 

 in the daytime. I am a beginner in 

 rose culture. H. S. 



To exterminate green fly it is only 

 necessary to use some good tobacco 

 preparation, either in the form of spray 

 or as a fumigant. Tobakine, Nico- 

 fume or Nicoticide, when used as a 

 spray, should be in the proportion of 

 one-half ounce to one gallon of wa- 

 ter. If used as a fumigant, painting 

 the pipes with the liquid without dilu- 

 tion will do the work. 



To kill mildew, take air-slaked lime, 

 one part; flowers of sulphur, three 

 parts; mix to the consistency of paint; 

 paint your pipes with this every week. 



A temperature of 65 degrees at night 

 is too high for these varieties. Ke- 

 duee the night temperature to 58 de- 

 grees and the day temperature to 75 

 degrees, if possible. On cloudy days 

 the temperature should not exceed 65 

 degrees. Keep the ventilators a little 

 open whenever possible, even when fir 

 ing. Ribrs. 



ROSE CUTTINGS OUTSIDE. 



I am planning to start some rose cut 

 lings outside. What is the best time to 

 put them in? Is it too late here in 

 Walla Walla, Wash.? Is it advisable 

 to start them in the greenhouse and 

 plant them outside next spring? Do 

 they need covering in winter? If so, 

 what is the best to cover them? How 

 large must I take the cuttings? 



W. W. F. C. 



Cuttings of roses can still be taken in 

 your section with success in the open. 

 A light covering of leaves, weighted 

 with brush to prevent blowing away, 

 should be put on as soon as the ground 

 freezes. Cuttings for outside work 

 should be from eight to ten inches long. 

 To raise them in the greenhouse from 

 wood from outside, the cuttings should 

 be taken before the bushes have had 

 time to ripen and shed their leaves. 



Cuttings from wood from indoor stock 

 can be inserted in sand at any time 

 from now on to March .15. These cut- 

 tings should be from half-ripened wood 

 and have from two to three eyes. Give 

 them a temperature of 62 degrees in the 

 sand, with a house temperature of 52 

 degrees. Never allow them to become 

 dry. Ribes. 



FEEDING ROSES. 



I should like to ask whether roses 

 should be fed as early as this. The 

 varieties are Bride, Maid and Rich- 

 mond. They were planted in June and 

 have received one inch of top cultiva- 

 tion each week since then. The soil 

 is heavy loam, one-fifth part manure. 

 One hundred pounds of steamed bone, 

 per bench 100 feet long, were applied 

 before planting. The plants have three 

 to six branches, sixteen to twenty-four 

 inches long, but do not grow as wo 

 think they should. J. T. 



Stock such as you describe is now 

 sufficiently strong to stand feeding. 

 This can be applied in the form of a 

 mulch consisting of one part good 

 fibrous loam and two parts decomposed 

 cow manure, if available. Sheep 

 manure can be substituted for cow 

 manure. Feeding can also be applied 



with benefit in the liquid form; ire 

 such form it is quicker in its action,, 

 being more easily assimilated.

TWO NEW ROSES. 



Under this heading an article ap- 

 peared in The Review of October 13 

 describing Melody and Double Killar- n 

 ney grown by Robert Scott & Son, at 

 Sharon Hill, Pa. So well do these two^ 

 new varieties promise that the S. S. 

 Pennock-Meehan Co. has decided to of- 

 fer the young stock to be distributed 

 next March with their favorable recom- 

 mendation. This means that the Pen- 

 nock-Meehan Co. believes that both 

 Melody and Double Killarney have 

 merit that entitles them to be ranked 

 with White Killarney. Samuel S. 

 Pennock took flowers of both varieties 

 to the New York Florists' Club meet- 

 ing November 14, where a prelimi- 

 nary certificate was awarded to each 

 variety, the chairman of the club's 

 committee on novelties, Charles H. 

 Totty, promising that his committee 

 would see the roses growing at Sharon 

 Hill and make a further report. .^Ed- 

 ward J. Fancourt, secretary of the 

 Pennock-Meehan Co., said that Alex- 

 ander Montgomery, of Natick, Mass., 

 and William Nicholson, of Framing- 

 ham, Mass., had seen Melody and 

 Double Killarney growing and had 

 heartily commended them. With such 

 powerful backing for the yellow and 

 the pink rose, a fair trial is assured by 

 all wideawake rose growers. Phil. 



MILDEW ON OUTDOOR ROSES. 



Please tell me what to do for mil 

 dew on outdoor roses. Climbers are 

 particularly subject to the disease in 

 this locality. I live in Neodesha, Kan. 

 A. C. S. 



Dust with Slug Shot. Do this during 

 the early morning while the dew is on 

 the leaves. 



Repeat this at least once a week, 

 until the trouble disa])pears. Ribes. 



SWEET PEA BUDS DROPPING. 



What is the cause of our sweet pea 

 liuds turning yellow and dropping? The 

 houses are well ventilated and kept at 

 a night temperature of 45 to 50 de- 

 grees. The plants seem to be perfectly 

 healthy, but the buds do not mature. 

 Is it advisable to use nitrate of soda on 

 sweet peas to make them bloom? If 

 not, what is good? F. B. 



The average night temperature, when 

 the sweet peas are flowering, should be 

 48 to 50 degrees. I would not let it go 

 as low as 45 degrees. Not knowing 

 wliether your plants are on beds or 

 raised benches, or the condition of the 

 soil, it is diflScult to say whether or 



not this has some bearing on the hxuh- 

 dropping. A too dry condition, too 

 much moisture at the roots, or imper 

 feet drainage would each help to cause 

 the trouble you have. Allow the soil 

 to dry out fairly well between water 

 ings. Loosen the surface soil so that 

 it does not have a baked or slimed-ovei 

 appearance, and ventilate freely on aii 

 possible occasions when the tempera 

 ture rises over 55 degrees. On cloudy 

 days the temperature should be 56 to 5.> 

 degrees, while with sunshine it can run 

 up to 65 degrees or even more. 



I would not advise using nitrate of 

 soda on the peas, either now or later. 

 They should not yet need feeding, and 

 as you state the vines are perfectly 

 healthy, lack of plant food is not the-
