BOSES TO CARRY OVER. 



What roses are best to carry over for 

 another year, own root or grafted? Can 

 American Beauties be carried over a 

 second year? Which rose is the better 

 for greenhouse culture, Bride or Kai- 

 serin? Will it be too late to plant 

 roses in August and have good flowers 

 in December? C. L. 



Eoses, either on their own roots or 

 grafted stock, can be carried over suc- 

 cessfully and profitably if given care- 

 ful and skillful treatment. Beauties 

 also can be carried over, but it is not 

 a usual practice; the inference there- 

 fore is that it is not a profitable meth- 

 od. Kaiserin is simply a good summer 

 rose. Brides are more suitable for win- 

 ter blooming. August is rather late to 

 secure full crops in December, but still, 

 with good treatment, a fair cut can be 

 obtained. Kibes. 



MILDEW ON HELEN GOULD. 



I enclose some leaves from a Helen 

 Gould (Balduin) rose that are in a 

 sorry plight, although the bushes have 

 been blooming profusely and other 

 varieties in the same bed are little af- 

 fected. Please name the trouble and 

 remedy. J. E. D. 



The leaves were in a bad condition 

 when they reached me, too much dried 

 up to see what the trouble is. They 

 are, however, affected with mildew, and 

 the remedy for this is sulphur. Choose 

 a bright day and close the ventilators 

 (if the plants are under glass) and give 

 a liberal dusting. This should be done 

 twice a week. 



If the plants are outside, choose the 

 early morning, whiie the foliage is 

 moist with dew, and apply the sulphur 

 or Slugshot. Kibes. 



ROSE PRINCETON. 



Eeferring to Rose Princeton, illus- 

 trated in The Review of June 23, Stock- 

 ton & Howe, with whom it originated, 

 say: 



"Princeton is a seedling, its parents 

 being Ulrich Brunner and Safrano. The 

 color is rose pink, as near as we can 

 describe it, but it is a quite unusual 

 color, being a true pink, and all blooms 

 'being of the same shade winter and 

 summer. The bud is long and graceful 

 and opens into a large flower, which 

 does not fade or fall; it is a remarkably 

 good keeper. Its growth is strong, vig- 



Burnink Cayenne pepper in the houses 

 will, if persisted in, certainly lessen 

 their number. This can be done when 

 fumigating the houses, or at any other 

 time during the afternoon or evening of 

 a cloudy day. For each 1,000 cubic 

 feet of space use one-quarter of a pound 

 of fresh Cayenne and keep the house 

 closed tightly till morning. Repeat 

 twice a week. Keep the walks and un- 

 derneath the benches clear of weeds 

 and, if possible, burn all the herbage 

 in proximity to the houses. Eibes. 



orous and fast, and free, every shoot 

 producing a bud. The stems are long, 

 straight and stiff. We are devoting one 

 large house to this rose, and believe it 

 to be different from any rose grown, 

 and of great promise." 



THRIPS. 



I should esteem it a great favor if 

 you would advise me how to get rid 

 of thrips on roses and carnations. I 

 have tried fumigating, but to no pur- 

 pose. The pests get into the buds of 

 both carnations and roses, and dis- 

 figure the petals to such an extent that 

 many of them are quite worthless. The 

 foliage, to all appearance, is free from 

 thrips. They seem to work only on the 

 blooms. G. W. E. 



Thrips at this season are difficult to 

 destroy or even to hold in check, es- 

 pecially when they have such a foot- 

 hold. 



GLADIOLI FOR CHRISTMAS. 



When should gladioli be planted to 

 be in bloom at Christmas? 1 want May 

 and Augusta and others of that class. 

 B. B. C. 



Christmas is too early for blooming 

 any gladioli. Such varieties as May 

 and Augusta cannot be bloomed satis- 

 factorily before March. The bulbs of 

 these are not procurable until Novem- 

 ber and, even if benched at once, it is 

 impossible, of course, to flower them 

 befor late winter. They can be planted 

 in benches and do well in a carnation 

 temperature. 



The small flowering gladioli, such as 

 Colvillei The Bride, Peach Blossom, 

 Blushing Bride, Mathilde and others of 

 the nanus type, are procurable two 

 months earlier than May, Augusta and 

 other large flowered sorts and can be 

 profitably grown in flats containing 

 four inches of soil. They will not 

 bloom for Christmas, however; none of 

 the gladioli will tolerate much forcing. 

 It only weakens the stems and spoils 

 them. C. W. 



SEASONABLE ORCHID NOTES. 



Miltonia Vexillaria. 



Miltonia vexillaria is one of the 

 most valuable of summer-flowering or- 

 chids. Some orchid collections prac- 

 tically ignore this beautiful orchid, 

 from a mistaken idea that it is hard 

 to grow. Miltonia vexillaria is much 

 easier to grow than such odontoglos- 

 sums as crispum and Pescatorei. It 

 will stand more heat and shows no ill 

 effects from even our hottest waves, 

 when we can see odontoglossums sim- 

 ply pining away. At this season mil- 

 tonias are better in a north house, 

 where blinds can be drawn down as 

 shade, and these also help greatly to 

 reduce the temperature in the house. 

 Plenty of air should, however, be given. 

 Closing up the house and constant soak- 

 ings of the floor may make the house 

 cooler, but it is a bad atmosphere for 

 either man or plant. Now the real 

 summer weather is here and thrips 

 must be guarded against. 



Keep the plants only moderately 

 damp at the root while in flower. Any 

 repotting should not be done until the 

 flowering season ends. There is no bet 

 ter potting medium than pure osmunda 

 fern fiber, and pots seem to grow tho 

 plants better than pans and baskets. 

 The cool end of the cattleya house, 

 with a minimum temperature of 52 to 

 55 degrees, suits M. vexillaria in win- 

 ter. There was a beautiful display of 

 this grand orchid at the late Boston 

 show, and it was noted that many oi 

 the critical visitors admired them much 

 more than the larger, showier, but stif- 

 fer-looking cattleyas. 



Cattleya Harrisoniae. 



With the passing of C. Mossioe ami 

 Mendellii, there is something of "^ 

 scarcity of summer cattleyas. It is true 

 there are C. gigas and C. Gaskelliana. 

 but too many growers overlook C. Har 

 risoniffi, sometimes classed as a form 

 of C. Loddigesii, an old orchid but n. 

 useful one. The flowers, it is true, lack 

 the size of many of the other cattleyas.
