Questions by our readers In line with any of the topics presented on this page will be cordially received and promptly answered 

 by Mr. Euzicka. Such communications should Invariably be addressed to the office of HORTICDLTDRE. 



Burning of the Foliage on Roses 



( In reply to inquiry) 



In reply to inquiiy rceived ou the IStli inst. we would 

 say that jjure, clean water will scorch and scald the foli- 

 age of the roses if it is ajjjalied when the plants are a 

 little dry at the root. Tobacco smoke will do the same 

 thing. This is especially true of houses that have a 

 large amount of concrete flooring, for then the air is 

 almost perfectly dry, unless provision has been made to 

 supply a steady amount of moisture to help keep the 

 atmosphere in prime condition. As for sjDraying the 

 plants every now and then, we would think it best to 

 leave that out altogether. An occasional syringing to 

 keep out that ever-present little brute — red spider — will 

 be all the spraying that the plants will require to keep 

 them in good health. Before each syringing make sure 

 that the plants are all wet enough. Better go over them 

 very lightly with a hose very early in the morning to 

 make sure. Then syringe after nine o'clock and you 

 will be on the safe side. Also the damping down; we 

 think it is very much out of place in the rose houses. 

 It may be all to the good in other branches of the busi- 

 ness but keep away from all damping down in the rose 

 houses. WTicre the floors of the houses are all of con- 

 crete, and perhaps the benches, too, put some ashes or 

 something similar over the walks, say two inches deep. 

 This will keep the moisture in the houses about right, 

 to say nothing of reducing the temperature in general. 

 The trouble with this damping down is that usually the 

 tiling is carried altogether too far, and the growth, is 

 likely to become too soft. Then in the fall instead of 

 having a lot of healthy plants that will resist mildew 

 and about half a dozen other diseases which lie in wait- 

 ing, you will have a good dose of mildew before you 

 know it, and it will take the plants until spring to re- 

 cover from this one attack. With Beauties, blackspot 

 is liable to set in, which is almost as bad as the mildew 



— much worse in fact as mildew can be killed, leaving 

 only the marked foliage to tell the tale. To go on with 

 the cause of burned foliage; sometimes the glass will not 

 be as good as it might, and there will be quite some 

 burners, or "cats' eyes," as these spots are sometimes 

 called. Of course the leaves will burn only in places and 

 not throughout the whole house. Go over these places 

 with a brush and some paint, and cover the spots well. 



Tying the Young Beauty Plants 



It does not pay to be in too much of a hurry to tie up 

 the young plants, as it does them good to lie around a 

 little, before being strung to the wires. You will find 

 the plants will break much easier from the bottom when 

 they lie bent over, and as long as they are not damaged 

 by syringing they can so remain. When finally tying 

 the plants it is advisable to tie them on a little slant, 

 instead of straight up. This will give the new bottom 

 shoots a better chance to grow, and as soon as they are 

 fairly up, and the mother shoot has a bud, the latter can 

 be cut away at the very bottom, leaving the plant com- 

 posed entirely of the new shoots, as the old mother shoot 

 seldom amounts to anything, usually throwing a lot of 

 weak wood that will just run and run, and never bloom, 

 lieing only in the way of the other shoots which produce 

 the flowers. 



Manure for the Early Mulches 



It is high time for the manure pile to be in shape if 

 nothing has been done to it as yet. The manure in- 

 tended for the early mulches should have been turned 

 over several times by this time. Keep it wet, too, to 

 keep the pile cool, or it will burn very likely and then 

 be practically worthless as far as plant food is concerned. 

 A little new, good sod added to the pile at each turning 

 will do wonders in holding moisture, and absorbing all 

 the liquids so valuable to plants, and which would other- 

 wise be lost. 



BRITISH HORTICULTURE. 

 The R. H. S. Summer Show. 



A wide variation of summer blooms 

 in all their grandeur were to be seen 

 at the annual summer show ol; the 

 Royal Horticultural Society, held at 

 Holland House, Kensington, ou July 

 1st and two following days. The so- 

 ciety had a difficult task to excel the 

 recent magnificent exhibition at Chel- 

 sea. The show, of course, was not on 

 such an extensive scale but the high 

 standard of excellence was in keeping 

 with the society's meritorious record. 

 The exhibits were arranged in seven 

 large marquees. Contributions were 

 received from some 120 exhibitors of 

 flowers. The Coronation challenge 

 cup, given for the best exhibit, was 

 awarded to Sander & Sons, for their 

 orchids. The firm also received a 

 first class certificate for .Miltonia San- 

 derae, and an award of merit for Cat- 

 tleya Mossiae Dreadnought. Roses 

 were numerous and interesting. In 



the group of Chas. Turner there was a 

 new scarlet Rambler, Coronation, of 

 promise; also a sport from Lyon rose, 

 a semi-double with buff-tinted blooms. 

 Shower of Gold is a new Rambler with 

 small yellow flowers, — this was exhib- 

 ited by Paul & Son. Prank Cant & 

 Co. showed Miss Ada Francis, a new 

 Rambler with blooms similar to those 

 of Goldfinch, and Braiswick Clirome, 

 a new Wichuraiana with yellow-tinted 

 blooms. W. Easlea staged Cherry 

 Page, a new decorative hybrid tea, 

 with cherry pink blooms shaded with 

 yellow. Sweet peas made a brilliant 

 display. Sutton & Sons had a fine ar- 

 ray, as did also Dobbie & Co. Perpet- 

 ual flowering carnations lent their gor- 

 geous coloring to the scene. 



The Rose Show. 



The annual show of the National 

 Rose Society on .July 4th was bigger 

 and better than ever. It was undoubt- 

 edly the largest display in the society's 

 37 years' experience. The nursery- 

 men's champion trophy for 72 blooms 



fell to B. R. Cant & Sons, whose col- 

 lection included a new crimson seed- 

 ling hybrid, Augustus Hartmann. Alex. 

 Dickson & Son were second and Prank 

 Cant & Co.. third. In the class for 

 nine blooms of any new rose, Jas. 

 Cocker & Sons were first with Mrs. 

 Andrew Carnegie, a new H. T. de- 

 scribed as "a sweetly scented Prau 

 Karl Druschki." This had previously 

 received a gold medal from the Nation- 

 al Rose Society. In a class for 40 dis- 

 tinct varieties, Alex Dickson & Son 

 were first, their exhibit including a 

 new crimson variety, Conway Jones; 

 B. R. Cant & Sons were second, and P. 

 Cant & Sons third. There was a splen- 

 did display of seedlings — always a 

 special feature of this show. Alex. 

 Dickson & Sons received a gold medal 

 for Queen Mary, old gold. Mrs. James 

 Lynas is a new H. T., or blush pink. 

 whilst Brilliant is a scarlet crimson, 

 with rather loose blooms. The two 

 last-named were exhibited by Hugh 

 Dickson, and each received a gold 

 medal. "W. H. Ahsett.
