is not washed off by rairi. We have 

 discontinued the heavy shading formerly 

 practiced at housing time. We find that 

 if the plants are in good condition they 

 will reestablisli themselves more quickly 



under cnly a moderate shade. Frequent 

 light syringing is required for a few 

 days, to prevent shriveling, but the 

 growth starts strongly from the begin- 

 ning. A. F. J. Baur. 



CARE OF THE YOUNG STOCK. 



Sttrrinsf the Soil. 



Now that planting is practically fin- 

 ished, the care of the young stock should 

 be the most important work for some 

 time to come. During the growing sea- 

 son the care and attention bestowed on 

 the young stock means, in a great 

 measure, the success or failure of the 

 entire season. 



Of the utmost importance to the young 

 plants is the regularity and thorough- 

 ness of cultivating. This is a part of 

 the work which cannot be neglected, not 

 only for the elimination of weeds, but 

 also that the surface of the soil may be 

 kept in the proper condition to absorb 

 light and heat and that evaporation may 

 be perfect. 



When the surface of the soil is al- 

 lowed to cake, it is in the worst condition 

 possible to perform these most essential 

 functions, and hence the necessity of 

 frequent stirring. The liberal use of 

 water demanded at this season and the 

 rapidity of evaporation will soon put the 

 surface of the soil in a caky condition. 



Insect and Fungous Pests. 



Next in importance is to keep the 

 young plants clear of insect and fungous 

 pests. 



Among our worst enemies at this sea- 

 son we may place red spider. Where 

 there is a good pressure of water and a 

 willing worker at the nozzle, this pest 

 need give little trouble, for, although a 

 prolific breeder and insidious in its at- 

 tacks, it cannot withstand the effects of 

 cold water applied with force. Greenfly 

 will also require to be looked after, as its 

 presence in the house is at all times un- 

 desirable. The means of destroying this 

 enemy are many and simple, and most 

 of them are effective if applied in time. 



A sharp lookout must be kept for mil- 

 dew, as this is one of the most de- 

 structive, persistent and annoying of the 

 summer troubles. In this case, preven- 

 tion should be the motto, as the most 

 rapid and effective cures still leave the 

 plants in a more or less debilitated con- 

 dition. Prevention consists in a thor- 

 ough knowledge of the laws of ventila- 

 tion, with a knowledge, also, of the effect 

 of these lavAs on the temperature and at- 

 mosphere of the iiouse and the effect of 



these conditions of temperature and at- 

 mosphere on the germination and growth 

 of this fungus. When this question has 

 been thoroughly discussed and solved, 

 mildew should no longer be a terror to 

 the grower. 



Sulphur for Mildew. 



As a remedy for mildew there is as 

 yet nothing that can compare with sul- 

 phur. During summer, when there is no 

 firing, it is a little more difficult to re- 

 lease the fumes, and also not quite so 

 easy to conserve them long enough to be 

 of full service, as during the colder 

 months, when the ventilators can be 

 closed long enough to effect the purpose. 



The use of the Peerless sulphur blower 

 at this season will, if intelligently done, 

 soon eradicate the pest and keep the 

 plants clear of it. I have found that by 

 using one- third finely sifted air- 

 slaked lime to two-thirds of flowers of 

 sulphur, the powder is more easily 

 distributed and equally effective. 

 This dusting should be applied at 

 least once a week, choosing a bright 

 day and closing the ventilators during 

 the operation, so as to allow the powder 

 to settle evenly. Even if the temperature 

 approaches 100 degrees no harm will be 

 done, if not allowed to remain too long 

 at this notch. Ribes. 



ROSE VISCOUNTESS FOLKESTONE. 



Bose Viscountess Folkestone has many 

 admirable qualities as a garden rose in 

 California and should be more generally 

 planted, at least in the coast section. It 

 is with me the freest bloomer of tho 

 hybrid tea class, the flowers are uni 

 formly high grade, the petals of the 

 flowers drop instead of drying on tho 

 stem and becoming unsightly, and the 

 blooms show less injury from fogs than 

 those of most other roses. It seems to 

 be happy and make vigorous growth in 

 almost any soil and location. With me it 

 has proven to be much the most satis 

 factory of any of its class. It is so 

 nearly a continuous bloomer that some 

 catalogues class it with the monthly 

 roses. 



The illustration shows a plant of this 

 rose in my garden, which is in the section 

 bordering on Monterey Bay. G. L. G. 



BLACK SPOT ON BEAUTIES. 



[With reference to black spot on Beauties, 

 a discussion of which was begun on page 8 of 

 the Review of July 22, in response to O. H. A.^ 

 inquiry, it is a pleasure to be able to supply 

 the following additional information.] 



Black spot on Beauties is a fungous 

 disease which develops beneath the skin 

 of the leaves. This makes it difficult to 

 combat, as the spores have to be killed 

 before they take root, as it were, on 

 other leaves. A warm, damp atmosphere 

 causes black spot to spread rapidly when 

 once started, so the first thing to do to 

 check it is to keep the plants a little on 

 the dry side and give plenty of ventila- 

 tion. If possible, have the spotted leaves 

 picked from the plants, and spray thor- 

 oughly with ammoniacal solution of cop- 

 per carbonate two or three times a week. 

 Sulphur painted on the steam pipes will 

 help keep it in check. Endeavor to get 

 the plants growing vigorously, and they 

 will, if care is taken with the watering, 

 syringing and ventilation, grow out of 

 the disease. 



The best cure, after all, is prevention. 

 WherQ there is a tendency to black spot, 

 seize every opportunity to get steam 

 around the houses at nights, at the same 

 time keeping the ventilators open. See 

 that there are no places where the water 

 tins from the roof onto the plants, and
