ROSE GROWING UNDER GLASS 



, CONDUCTED BY 



Questions by our readers In line wim any of tlie topics presented on tliis page will be cordially received and promptly answerei" 

 by Mr. Ruzlcka. Such communications should InTarlably be addressed to the office of HORTICbLlURt. 



Weeds Around the Houses 



AMth more rain, which we have been having, the weeds 

 all around the greenhouses will flourish as they never did 

 before, providing they are allowed to do so. Even in 

 spite of all the work that may have to be done inside it 

 will pay the growers to spend so much time every week 

 on the outside of the greenhouses. The place that can 

 boast of a lawn will generally boast of the highest divi- 

 dends. The cleaner the place on the outside the easier 

 it will be to keep it so inside, for the weeds will not be 

 harboring insects of a hundred different species, and 

 plant diseases, which are bound to affect the roses in 

 either direct or indirect way. Therefore clean up. 



The Coal Bin 



NO, it does not pay to say that there is time enough 

 to worry about the coal when it gets cold. The progres- 

 sive grower will have his coal ordered and in the bins 

 long before the winter sets in. That is why the place 

 pays better, for everything is done when it should be and 

 results show up accordingly. The boilers, also, should be 

 in very good shape in order to be ready when they are 

 called to do duty. In case the whole heating system has 

 not been overhauled during the summer months it will 

 pay to go over all the pipes at once before much heat is 

 used, as all the pipes will then be hot and work can go 

 forward only with the greatest difBculty. 



Tarring Roofs of Worksheds 



This is another item that is not exactly rose growing, 

 and yet it has considerable to do with it. When the 

 winds blow in the winter many roofs are torn up and it 

 costs a good deal to repair them. Much of this damage 

 could be avoided if the roofs were tarred once in a while. 

 The best time to do this is while the weather is still 

 warm and the roofs perfectly dry. Apply the tar hot, 

 and then sprinkle some sand to dry the tar, at the same 

 time making a very durable coating for the roof. 



The Night Temperature 



Now that the nights are getting to be quite cool, the 

 night temperature should receive careful attention, or 

 mildew will he likely to start in. It is best not to let the 

 houses drop down too low, for the thermometer often 

 runs up a good deal in the daytime. Do not close the 

 ventilators altogether at night. It is much too early in 

 the season to begin this kind of work. Better leave on 

 at least a crack of air. using artificial heat to hold up the 

 temperature, if necessary. About 64 degrees F. is right 

 for most of the roses now in cultivation, and the roses 

 will grow much quicker if run this way. Then, too, the 

 houses will run up in the daytime, and it does the roses 

 no good to have too great a difference between the day 

 and night temperature. 



BRITISH HORTICULTURE. 



At the annual meeting in London 

 of the Horticultural Trade Associa- 

 tion, Wm. Cuthbertson of Debbie & 

 Co., Edinburgh, was unanimously 

 elected president. 



from K. Velthuys. Hillegom; Pink Per- 

 fection, soft pink, from P. Hopman & 

 Sons, Hillegom; Libesfeuer, scarlet, 

 from De Ruyter, Noordwijlt, and Love- 

 liness, creamy white, from the last 

 named grower.

A New Tomato. 



Amongst the exhibits at the show 

 of the Royal Horticultural Society on 

 August 26 was a new tomato. Buck's 

 Tresco. shown by Chas. H. Buck, of 

 the Tresco Nursery, Ipswich. The 

 fruit is of a suitable size for commer- 

 cial purposes, well colored, and of ex- 

 cellent shape, whilst the flavor is 

 everything that can be desired. The 

 sample trusses indicated that the new 

 tomato is a heavy cropper. Each plant 

 usually carries not less than 28 pounds 

 of fruit under ordinary culture. 



BLACK SPOTS ON CARNATION 

 FOLIAGE. 



Editor HORTICULTURE: 



I am sendin;? you carnation leaves af- 

 fected with black spot.s. The plants are 

 benched for some time. We have sprayed 

 with insecticide but it seems to have no 

 effect. V\'e would be very much obliged if 

 vou could tell us what it is and what we 

 could use to stop it. 



Tours sincerely. 



Long Island. A. R, 



Gladiolus Show in London. 



At the summer show of the National 

 Gladiolus Society, held in the Royal 

 Horticultural Hall, London, a first- 

 class certificate was awardfed to Elec- 

 tra, a useful scarlet, with the lower 

 petals containing a tinge of white, 

 shown by P. Hopman & Sons, Hille- 

 gom. Awards of merit were allotted to 

 the following: Prince of Wales, sal- 

 mon with a yellowish centre, from C. 

 van Zanten, Hillegom; Mrs. Frank 

 Pendleton, flesh pink with dark centre, 

 from Firma Vos Mz, Sassenheim, Haar- 

 lem; King of the Blues, dark blue, 



The sample of carnation foliage 

 which come with foregoing is, we 

 think, affected with a fungus arising 

 from a heavy mulch of cow manure, 

 which will appear a week or so after 

 mulch is put on. As it ripens, these 

 spores (if that is what they are), are 

 thrown out on the foliage or even the 

 bench boards and stick there. No 

 doubt Bordeaux would help in spraying. 

 In answering the query, we would ask 

 if cow manure, fresh, was used as a 

 mulch? We don't think the fungus 

 propagates on the carnations, and, 

 aside from looks, hardly think it dan- 

 gerous.

FRUIT AND NUT GROWERS TO 



MEET. 



An event of national importance to 

 fruit and nut growing interests of this 

 continent will occur in Washington, D. 

 C, November 17 to 22. On this occasion 

 the American Promological Society, 

 The Society for Horticultural Science, 

 The Eastern Fruit Growers' Associa- 

 tion and the Northern Nut Growers' 

 Association will meet as a unit event 

 designated as Fruit Week. The pro- 

 grams and business of the separate or- 

 ganizations will be conducted inde- 

 pendently in the same building, while 

 all exhibits will be displayed in com- 

 mon, though entries shall be made 

 through the respective bodies, thus 

 keeping the identity of each intact. 



Ample cold storage space has been 

 provided near the meeting place and 

 persons contemplating making an ex- 

 hibit of perishable fruits may forward 

 material well wrapped and packed to 

 the Washington Market Company, who 

 will care for it at a very nominal 

 charge. All packages should be plain- 

 ly market "for the American Pomo- 

 logical Society." Requirements for ex- 

 hibit space should be filed before Oc- 

 tober 1.5 with the secretary of the Po- 

 mological Society, who may be ad- 

 dressed at 2033 Park Road, Washing- 

 ton, D. C. Application for entry for 

 Wilder medals should also be made to 

 the secretary of the society not less 

 than ten days previous to the date of 

 meeting.
