PUNCTURES IN ROSE STEMS. 



I am sending, under separate cover, 

 a twig taken from a rose plant grown 

 under glass. The stems are punctured 

 at intervals of an inch or so, and I 

 find that there is an egg about an 

 eighth of an inch long in each puncture. 

 The work of this insect is not yet ex- 

 tensive among my plants, but I should 

 like to know what it is and what to do 

 with it. r. E. E,— Mo. 



The punctures referred to are caused 

 by grasshoppers, which bite into the 

 stems of the roses, bruising the stems, 

 and lay their eggs in the bruise. As 

 the stems are cut off, either on account 

 of wilting or with the flowers, before 

 the eggs have, time to hatch, the punc- 

 tures do not affect the plants in any 

 way, and by keeping the doors and side 

 ventilators closed they can be prevent- 

 •ed almost entirely. W. J. K. 



LOSINQ THEIB FOLIAGE. 



I am sending you, by express, two 

 Killarney Brilliant roses and shall 

 greatly appreciate any advice you can 

 give me about them. I am finding 

 plants in this shape all over the house, 

 but especially in the center row. Three 

 rows in the middle bench look fairly 

 well, but the plants in the fourth row 

 look like those I am sending you. They 

 always get new foliage, which then 

 turns yellow and falls off. AVill you be 

 kind enough to tell me what the trouble 

 is, and the remedy? W. K.— Mo. 



The writer does not state whether 

 the roses are planted in raised benches 

 or solid beds, and he fails to give some 

 other particulars that might aid in 

 ■determining the cause of his troubles, 

 but it seems from his letter that the 

 Brilliants are planted in a bench con- 

 taining seven rows of plants, in the cen- 

 ter of the house and probably, under the 

 ventilators, where they are liable to 

 get considerable drip when it rains. 

 Besides, in watering a bench wide 

 ■enough to hold seven rows of plants, a 

 good many growers water from each 

 side to the center, causing the center 

 row to receive a double dose at each 

 watering, and also piling up an extra 

 quantity of soil in the center of the 

 bench, around the plants. Therefore, 

 as the center of the bench naturally 

 dries out most slowly, these plants 

 probably are continually soaked. This 

 causes the plants to make soft growth, 



and the leaves turn prematurely yellow 

 and fall off. 



The best way to overcome this 

 trouble will be to let the bench get fair- 

 ly dry all over and then water entirely 

 across the bench from both sides. In 

 this way the outside rows will get most 

 of the water, and any loose soil will be 

 washed to the edges instead of being 

 piled up in the center of the bench. 

 Then the center plants will dry up as 

 fast as the rest. Killarney Brilliant is 

 not as easy d rose to grow as any of 

 the other Killarneys and will not stand 

 as much water or as heavy feeding. 

 Hence, where Killarney and White Kil- 

 larney may do well, Brilliant may suf- 

 fer under the same treatment.

ORIGIN OF MANETTI. 



Since most of your forcing roses 

 probably are grafted on Manetti, it 

 may interest you to know that "the 

 Manetti stock was raised in Italy by 



Signer Manetti, of the Botanic Gar- 

 dens, Monza, and seems to be a hybrid 

 from E. fraxinifolia, a variety of E. 

 blanda. It is propagated by cuttings, 

 and is stated to have been first intro- 

 duced into England by Mr. Elvers so 

 long ago as 1835. It has some advan- 

 tages over all other stocks in that it 

 pushes early and the sap will run quite 

 late." The American supply comes 

 from England and France, most grafters 

 preferring the British output. The 

 stocks usually are grown in small lots, 

 by persons who sell them to the ex- 

 porters, who keep an eye on the grad- 

 ing to see that the standards are main- 

 tained. 



ROSES IN SOUTH CAROLINA. 



Will you kindly inform me if Shaw- 

 yer. Ward and Maryland roses will do 

 well if cut back as closely as Kil- 

 larney? If not, how closely should 

 they be cut back? 



M. J. M. E.— S. 0. 



You do not state whether you mean 

 pruning back the plants in starting 

 them for another year or cutting the 

 flowers. All the varieties mentioned 

 can be pruned back to sixteen to twenty 

 inches in resting the plants and start- 

 ing them for another year. If you 

 refer to the cutting of the flowers, they 

 should be cut to the first perfect leaf, 

 which is usually the second or third 

 eye from the break. When cutting 

 flowers, the varieties you mention will 

 stand closer cutting than Killarney, for 

 the reason that they grow more blind 

 wood and have more foliage to sup- 

 port the plants when the crop is cut.

SHRAPlsiTr 



Amsterdam, Holland. — To tide over 

 those engaged in the bulb industry and 

 other branches of horticulture, which 

 have been severely injured by the war, 

 the Netherlands government is consid- 

 ering the establishment of a credit 

 bank for horticulture. While the bank 

 will not be on a cooperative basis, it 

 is understood that the industries spe- 

 cially concerned will exercise a con- 

 trol over its management. 



Nice,' France. — The resumption of the 

 facilities of transportation by rail to 

 northern France and England has 

 made it possible for the flower growers 

 in this section to send cut flowers to 

 those markets. The sale of flowers is 

 one of the chief sources of the trade 

 in this district and it has suffered 

 largely by the war, as the principal ex- 

 portations went to Germany or through 

 Germany to northern capitals. 



Ghent, Belgium.— Under the direction 

 of German authorities the postal serv- 

 ice has been partly restored through 

 this section. The plant growers have 

 been encouraged to return to their 

 daily occupations and may now receive 

 and dispatch mail from and to other 

 countries. Subject to the interruptions 

 occasioned by military necessity, the 

 transportation lines also are open to 

 shipments. 



Lyon, France. — Georges Fernet, son 

 of the famous rose raiser, Jh. Pernet- 

 Ducher, has been killed in the Vosges 

 mountains. The death of his elder 

 brother, Claudius, was reported in 

 these columns some time ago. 



London, England. — Business with 

 firms in the horticultural trades is un- 

 steady, but not so bad as might be ex- 

 pected. In a general way the best class 

 of buyers are laying off, as they are 

 the people who are carrying the finan- 

 cial burden of the war, but the laboring 

 classes are actively employed at the 

 best wages ever known and the horti- 

 cultural firms that reach this group of 

 buyers find possibilities there this sea- 

 son at least as good as ever before. 



Brussels, Belgium. — The German civil 

 administration, which has been seek- 

 ing to reestablish Belgian industries, 

 has not looked with favor on the course 

 of the British government in requiring 

 deferred payAient through English 

 banks for Belgian exports. For a time 

 no such exports were permitted, but 

 it has been decided not to interfere 

 with exports of horticultural commodi- 

 ties from the Ghent district and re- 

 cently considerable quantities of plant 

 stock are reported to have been dis- 

 patched to Eotterdam.
