NEW aUIDE TO ROSE CULTURE. 



Why the Leaves may Fall. — When Roses drop their leaves after being potted, it is gener- 

 ally owing to the change of temperature and other conditions which the plant has experienced in 

 removal ; but it may result from too large a pot, or too much water. The best remedy is perfect 

 rest. Keep the plant quite dry till signs of new growth appear, then water very sparingly ; the 

 earth in the pots should not remain soaked, but should dry out quickly if the plants are in healthy 

 growing condition. 



General Treatment. — The conditions most favorable for growing Roses in pots are good, 

 rich soil, plenty of sunshine — the early morning sun is best when it can be had— reasonable and 

 regular heat and moderate moisture. The temperature may range from 40° to 50° at night and 

 from 60° to 80° in day-time. Plants should be washed or sprinkled frequently in blood-warm 

 water; the leaves should be kept clean and bright ; dust is injurious. If troubled with earth- 

 worms, water occasionally with weak lime-water or very weak tobacco- water. 



Roses for liVinter Bloom. — We furnish Roses suitably prepared for Winter bloom, in both 

 large and ordinary-size plants, whenever wanted, at the usual pdces. These are strong pot- 

 grown plants that have been kept hungry and are anxious to get a chance to grow. If 

 potted in good, rich soil, and put at once in a warm room, they will, with proper treatment, com- 

 mence to grow and bloom, immediately. 



INSECT ENEMIES OF THE ROSE. 



Roses which are strong and vigorous are not likely to be attacked by insects, or, if attacked, 

 are not easily injured. It is highly important, therefore, to keep your plants healthy and in good 

 growing condition, by liberal manuring and thorough cultivation. When insects appear, apply 

 the proper remedies promptly and vigorously, and in bad attacks stir the ground deeply with 

 hoe and rake every day. A little perseverance to resist the present attack is all that is needed ; 

 next year you may not be troubled with insects at all. 



Aphis or Green Fly. — The best remedy is tobacco smoke. It can be applied by covering the 

 plant with a box or barrel, and putting under a little burning tobacco. The plant should remain 

 in the smoke for several hours and then be thoroughly washed off with blood- warm water. If 

 more convenient to apply, a strong tea of tobacco will answer very well. Wash or sprinkle the 

 whole plant or dip it in the tea as often as may be necessary. For Roses in pots, a hot- water 

 bath will answer the same purpose. The water should be as hot as the hand can bear, say about 

 130 degrees, and the whole top of the plant dipped in quickly, two or three times in succession, 

 but it must not remain in more than two seconds at a time. 



The Rose Slug.— Slugs frequently appear suddenly and increase very rapidly. They must 

 be attacked instantly. Dust the plants thickly with powdered or air- slacked lime, plaster of 

 Paris, ashes, or even road dust, and repeat the same vigorously as often as may be necessary. If 

 more convenient, the plants may be thoroughly sprinkled and washed with a strong suds made 

 with soap and salt, or with brine alone. Slugs seldom appear more than once in a season, and 

 can easily be destroyed if taken promptly. 



The Rose Bug is of a grayish color and about one-half an inch in length. It appears sud- 

 denly in June, and feeds on the opening buds and flowers. The only cure is hand picking. This 

 is not a serious matter if attended to as soon as they appear. The 'best time to gather them is 

 early in the morning. They may be quickly brushed or picked into a vessel containing water, 

 after which they should be burned. 



Mildew does not usually kill Roses, but retards their growth and sometimes prevents their 

 blooming. It is believed to be induced by atmospheric causes, as sudden changes of temperature, 

 moisture, etc. For out-door plants, a thorough stirring of the soil, with a view to encourage 

 strong growth, is probably the best thing that can be done. In -doors the same treatment, with 

 the addition of a fine dusting of flour of sulphur over the whole plant. Sulphur is the best 

 known remedy for mildew. 



Red Spider is a very minute insect, first appearing on the underside of the leaves, and 

 though difficult to see, its effects are quickly noticeable by the browned or deadened appearance 

 of the leaves. It flourishes best in a hot, dry atmosphere, either in-doors or out ; moisture is its 

 greatest enemy. Sprinkle or wash your plants frequently , taking care to wash the underside of the. 

 leaves thoroughly, and you will not be troubled with Red Spider. In bad attacks it may be neces- 

 sary to sponge the leaves-daily with warm water until the pest is thoroughly destroyed. 



The Thrip is very destructive to Roses in some sections of the West ; it is a small hopper, 

 varying in color from black to brown, and is found on the underside of the leaves. The best 

 remedy is said to be a thorough wetting with a strong suds of whale-oil soap, or soap and salt, or 

 very strong tobacco tea, taking care to wet thoroughly the underside of the leaves. We presume 

 that ateaspoonful of Hellebore, or Paris Green, dissolved in a pail of water and applied in the 

 same way, would be equally effective. 



As all Insects like to be LET ALONE, and strongly dislike to be disturbed, they can fre- 

 quently be kept in subjection by vigorously hoeing and raking the ground every day, dusting, 

 sprinkling or washing the plants, and destroying the pests by every means in our power.
