DISEASE IN MARECHAL NIEL ROSE. 



BY WM. G. JOHXSOX. ITHACA, X. Y. 



I have just read the article by "VY., of iSTorfolk, 

 Ya., on disease of Marechal Xiel Rose, but 

 think he mistakes in assigning tlie cause to our 

 severe climate. 



Up to two years ago I think I had the finest 

 single specimen for its age (tlaree years) I ever 

 saw ; but now it is going in the way your cor- 

 respondent speaks, viz : a knotty formation 

 above the root. I had thought perhaps it was 

 being on its own root; but last week, on a visit 

 to the rose-houses of the late George Pum- 

 pelly at Tioga, N. Y., I found the great 

 Marechal Xiel rose in a worse condition 

 than mine — in fact, just about dead. It is a 

 grafted rose that Mr. Pumpelly procured at 

 Boston, about six years ago, and is a remarkable 

 bush, having a trunk at the graft, I should thmk, 

 some 18 or 20 inches in circumference. It is 

 mournful to see such destiiiction ; and can't some 

 of our horticulturists find a remedy ? I should 

 state that the Pumpelly rose is all right below 

 the graft, say 18 inches above the ground, liut 

 just above the Marechal Niel wood is affected as 

 mine is, and as your correspondent speaks. 



SIZES OF ENGLISH FLOWER POTS. 



BY MK. E. LOXSDALE, GEK3IANT0WX, PHILA- 

 DELPHIA. 



As it is apt to confuse some of the readers of 

 the Gardener's Mokthly, when reading ex- 

 tracts from English gardening jjapers, in which 

 the sizes of flower pots are too often technically 

 enumerated, I beg to herewith append a table 

 which, I trust, may be of service to them : 



Thumbs, 2 in. to 2i in.; sixty's (GO's), 3 in.; 

 forty-eighfs (48"s)., 4i in.; thirty-two's (32's), 6 

 in.; twenty-four's (24's), 8 in.; sixteen's, (16's), 

 9i in.; twelve's (12's), lU in.; eight's (8's), 12 

 in.-; six's (6's), 13 in.; four's, (4's), 15 in.; two's 

 (2's), 10 in. 



[Water heated to 120° is an infallible remedy 

 against all insects where the plants can be dipped 

 for an instant therein, and where a plant is 

 trained on a trellis it might, perhaps, be un- 

 twined and get a dip when infested. — Ed. G. M.] 



HOT WATER FOR MEALY BUG. 



r.v Av. n. p. 

 A few days ago I Ibund a young plant of 

 Browallia with a multitude of mealy bugs on it, 

 and as said insect is my favorite aversion, I put 

 the whole affair in the feeding tank of my hot 

 water fixings, and, I think, I fixed the bugs, 

 while the plant seems none the worse. "Water 

 not over 120= Fahr. Let '• Reader"" try it and 

 report. 



THE MEALY BUG. 



BY S. O. KNAPP, JACKSON, MICH. 



I notice your correspondent, '' Reader," in- 

 quires for a remedy for mealy bug : 



I have succeeded best in keeping them down 

 by using a small stream of water with consid- 

 erable force. I either plug the, end of the hose 

 nozzle or apply my finger, so as to produce a 

 stream say the size of a large knitting-needle, 

 then apply it directly around the leaves and. 

 flowers. This dislodges them at once, and with 

 less harm to the plants than any other remedy 

 I have tried. 



ACCOHOL FOR MEALYtBUG. 



BY II. G., E ASTON, PA. 



Your correspondent, "Reader," asks: "Is 

 there any cure for mealy bug?" 



I have been using for some years, and do still, 

 undiluted alcohol, applied with a small brush, 

 and find it quite satisfactory and much more 

 agreeable to use than whale oil soap. 



ASTRAP/EA WALLICHIJ. 



BY MANSFIELD MILTON, CLEVELAND, O. 



A small tree from Madagascar, having large 

 green leaves and gorgeous scarlet flowers, pro- 

 duced in large heads which are suspended in a 

 drooping manner on rather long stems. In the 

 greenhouses of Europe it has long been an 

 inmate, but is seldom seen in this country. It 

 requires a high temperature, but under good 

 conditions makes rapid growth. A plant Well 

 furnished with leaves makes a beautiful object 

 for out-of-door decoration during the summer, its 

 large dark green leaves making it very conspicu- 

 ous and ornamental. A large plant in a tub we 

 have here, formed, assocLated with other plants 

 of similar nature, quite a subtropical group on 

 the lawn this summer. It succeeds well in a 

 good rich fibrous loam, and when growing vigor- 

 ously requires abundance of water. Good drain- 

 age is indispensable for maintaining a sweetness to 

 the soil. Insects do not trouble it much if proper 

 attention be paid to its several requirements; 

 but if mealy bugs once get a foothold they 

 are difficult to eradicate, finding good shelter- 

 from the stipules at the base of the leaves.
