340 THE GARDENER. [July 1873. 



S. P. L. — Sow bone- meal in your lawn in spring, by wliicli means the grass 

 will be nourished, and it will gain ascendancy over the moss. You might rake 

 some of the moss out with a sharp-toothed rake, and sprinkle some rich light 

 soil over it as well. 



]M. W. — Sion House Improved, Telegraph, and Volunteer, are excellent 

 winter Cucumbers. Sow about the 12th of August. 



L. S. — You cannot do better than you propose, but it should be done 

 immediately. 



C. R. W, — Apply to the Secretary. 



A Subscriber. — Fire-heat will not be necessary now, unless during a con- 

 tinuance of dull damp weather, when a little heat will prevent stagnation of 

 atmosphere. 



A. H. — You cannot thinlc too much in the direction you name. It is folly to 

 think that improvement is not possible. Let us have no stereotyped editions 

 of gardening affairs. 



Bright Spade. — Thanks. Shall be glad to hear from you on any of the 

 subjects you name. 



A. C. Cade. — In so mild a climate we do not consider chambering necessary. 

 The depth of soil, if you do chamber, should be 2}^ feet. The more the rainfall, 

 the greater necessity there is for draining, of course. Outside borders managed 

 as you propose, are to be preferred to confining the roots to the inside. Late 

 Grapes require least fire-heat, and probably with coals so dear, will suit your 

 purpose best 



Mildew on Roses. — I should feel obliged if you, or any of the correspondents 

 of the ' Gardener,' can kindly give me any receipt to effect a cure of mildew, 

 either on fruit or Rose trees. I begin to think the best is to cut down the tree, 

 and consign it to the rubbish-heap ; for I find a tree once badly attacked is 

 liable to a fresh outbreak for years after. Dusting with flower of sulphur, or 

 washing with tobacco-water, are by no means cures. Mildew generally com- 

 mencing on the under side of Rose-leaves, for instance, is most difficult to 

 get at with sulphur. I have been troubled very much with it on forced Roses ; 

 and my outdoor Roses, which I never remember seeing in finer and healthier 

 foliage than at the present time, are here and there showing signs of this pest, 

 which spreads like wildfire if not daily looked after. I should be glad to hear 

 of anything more effectual than sulphur, the old remedy. 



[We will be happy to hear from our correspondents on this subject. — Ed.]
