JOURNAL OF HORTICULTURE AND COTTAGE GARDENER. 



[ May 23, 1867. 



We also request that correspondents will not mix tip on the 



same sheet questions relating to Gardening and those on 

 Poultry and Bee suhjects, if they expect to get them an- 

 swered promptly aud conveniently, but write them on 

 separate communications. Also never to send more than 

 two or three questions at once. 

 N.B, — Many questions must remain unanswered until next 

 week. 



GoLDEN-VETMKD VioLKTS (Oaklctj). — Tho leavcK you have sent to us are 

 very beautiful, and, aa they have been simihirly polden-veined in two 

 following ycara, tlie aport is probably permanent. Tf so, instead of "pre- 

 ventintr it," we think Komo one of the London florists would readily 

 purchuse the whole of your plants. 



CovEU POR Vol. X. ( ir. C).—Jt you euclofe fifteen poBtape stamps 

 \Tith your address to this office, you can have the cover went free by post. 

 As the Vine mildew has apptarcd in your vinery, dust all the leaves with 

 flowers of yulphur without delay. Syringe at the end of a week, and 

 repeat tho treatment until the mildew ceases to appear. 



Advertisemknt (R. G. Oakley).— li is in our last number, hut from 

 *' Roberts & Sons " 



Aspects iJ. H. H,). — For the purpose you mention, wo would decidedly 

 ase the south-east wall in prcfereneo to the north-west. "We cpunot state 

 the amount of pipinji in Mr. Meredith's houses which do so well, both on 

 the east and west aspects. Piping must be regulated according to the 

 lime tho fruit is wanted. 



COLEUS Vebscttaffelti for Pedding (J.J. G.).— ColeusVerschaflfelti 

 will do as a *' bedder " in a tolerably sheltered place. It does fvcll about 

 London, and was very fine last senson at Woburn Abbey. Mr. Fish has 

 done hitio good with it in his windy position, hut means to try it further. 

 It would be well to keep some Perillas in reserve. The specimen you 

 sent was of Eougainvillrea spectabilis. 



Covering Hot-Water Pipes for Bottom Heat (C. TT.I.— Your pro" 

 posal to place first a layer of stones round nnd a few inches over the 

 pipes, then rough inn, all the finer pnrt being sifted out, and at the top 

 for plunging the pots either the tine tan or sawdust, will answer admir- 

 ably, provided you take care that the rough tan over the stones that 

 surround the pipes does not become dry; then it will permit the heat to 

 rise freely. The moint state you may secure by having a pipe by means 

 fit which you cnn ijour water among the stones. Do not cover the pipes 

 with stones deeper than you cnn avoid— say B inches. We would put 

 washed fine gravel over the stones, and then the tan would not tind its 

 way among the larger ones. 



Tiffany (TijTtmy).~li was advertieed in our Journal last week. 



Peach Treks almost Destroyed (G. E, T.).— Probahlv the Peach 

 treesare .suffering from the severe frosts. Wc do not think that the early 

 pruning would affect them. We have lost shoots which were not pruned 

 at all. In your case, with water stnnding so near the surface, at the 

 other side of the wall, we should imngine that the border would be too 

 wet, and the wood, in tbe late dull autumn, iinpirfectly ripened. A drain 

 in front, from 81 to 4 feet deep, would be the best remedy. There are 

 very singular farta in connection with water in certnin positions. Water 

 stands as near the surface at the highest end of Mr. Lane's celebrated 

 •rchard-house vinery. 



Iksect Eatiwo Eosh Leaves iP. P.i.— It is a Curculio, or Weevil, 

 which eats the leaven of your Roses. We think it is C. maculatus, but 

 the specimen was too much crushed to he certain. Spread a white cloth 

 at night bene ith the trees and shake them. The insect feeds at night. 



Blistered Peach Leaves {A. M. H'.),— Pick them all off. They are 

 ♦aused bv cold checking the growth of the leaves whilst the supplv of 

 sap from the roots remains unchecked. Shelter by glass or other cover- 

 ing is a preventive of blistered leaves. 



Heating a Melon Pit (Lrnrnrr).— The brick pit 9 feet wide and 

 S feet below the ground level, which you have used for Melons, and as 

 yon cannot heat with dung and tan you propose to heat with a flue, 

 we would treat in this way." We would run n flue round on the floor, 

 2 feet from the front and li feet from the back. Above the flue, flow 

 and return, we would make a floor 3 feet from the glriss. Hate or stone 

 would be best, but stout slabs of wood would do very well. We would lay 

 these slnhs so that there should be from 2 to 4 inches between them. 

 These snuces wo would fill with clinkers, brickbats. &c, and rough 

 plaster them. On this platform we would place in the cectre of each 

 light, back and front, an open drain tile, or a wooden box, communicating 

 with the chamber in which the flues run, and furnished with a lid to let 

 out heat for tho atmosphere as wanted. By pouring water into these 

 openings you can have moist bottom heat at all times, and moist top 

 heat as you want it ; and there will be no danger of scalding, as tho water 

 will not touch the flues. For this system, if the flue is built, raised a few 

 inchcB above the floor, the water poured on will go over the w^bole of the 

 floor. If tho floDr was concreted all the better. The 3 feet will give 

 ample room for foliage and earth. There would be more trouble in heat- 

 ing the two divisions of your 18 feet pit separately, but you can com- 

 mence with that next the furnace, and give plenty of air to the farther 

 part until you wish to start it. The air makes all the difference. We 

 observe no red spider or other insects on tho Vine leaf, and tho blotches 

 are tbe result of scalding. The best remedy is early air-giving. 



Variegated Lobelia (J. B. p.).— Wo cannot form an opinion upon 

 such a specimen. Send a good plant in a pot to the Floral Committee of 

 the Royal Horticultural Society. 



Grapes Dark Coloured iJ. S. H.).— Though no bigger than Peas, 

 they are severely " spotted'— that is, they have a peculiar ulceration 

 which gardeners call "the spot." We believe it to be caused bv defective 

 root-action. If the roots are kept warmer and better nourished we think 

 the evil will not reappear. 



Dahlia Culture. (Dn^ilia),— We shall readily give information to any 

 jrrower of this flower; but we do not know of any difficulties in its 

 culture. 



Covent Gapden Market {J. Woods, jun.).— We know of no such per- 

 son as you need. The regular attendauta will not incur the trouble of 

 «ommissions. 



Pampas Grass Drying {W. H. J.).— The stems required for ornamental 

 purposes should be cut directly the flower-heads attain their full size, 

 and should bo dried in the sun. We can only account fur the glumes or 

 v;ilves falling from tlieir being cut when mature; washing them with. 

 water will not tend to their preservation. 



Tree Migkonette after FLOWEBrao {M. S.).— Mignonette is a peren- 

 nial in ft greenhouse, and after flowering may have the surface soil re- 

 moved and have a top-dressing of rich compost, the plant being kept 

 closely pinched; hut it will not flower nearly so finely as plants sown and 

 grown on for tho purpose. The flowers are smaller, and the plant losi 

 vigorous. 



EucHARis AMAZONiCA CULTURE fC if. itfojor).— The plant should hav* 

 a rest, which you may give at any season after tho plant ceases growtk 

 by withdrawing it by degrees from the hotbed, and keeping the soil dry, 

 but not BO as to cause the foliage to flag, and it cannot havo too much 

 light and air. The pot, we presume, is full of roots and the drainage 

 good. If the plant is growing do not check it, but allow tho growth to b» 

 made ; then when tho foliage attains its full size lessen the supply of 

 water gradually, and expose the plant fully to light aud air. This wiU 

 check the growth, but you must not lessen the amount of water so as t« 

 cause tho leaves to flag. It should have a rest of this kind for threa 

 months in every year; but probably your plant will soon bloom. 



Pancratium /nd Ismene asianc;e3 (Idem). — The Pancratium rcquirea 

 precisely the same treatment as the Eucbaris. The Ismcno amancres 

 also retjuiros the same treatment as the Pancratium, to which it is a 

 cloS(.'ly allied species. Tou Cannot give them too much encouragomont 

 when growing, nor ripen off too well by full exposure to light. The 

 (lotting should not be too liberal, for they flower more freely aud certainly 

 when the roots are confined. 



Rhododendron Falconeri Injured by Frost (A Subscriber). — Ton 

 miiy take up the plant from the open ground now, and you may cut it in, 

 this being a good time, an<l it will start better fr>-m tho part protected by 

 the snow than from tbe leafless portion of plant, that being the pait 

 injured by frost we presume. 



Soil for the Orange, LiaiE. Shaddock, ani> Cahellia (Idem). — Ton 

 cannot have a better soil for all those than the siu'face of a good and 

 rather light loamy pasture, the turf being cut ofl" from 1.^ to 2 inches lliick, 

 and being chopped aud made pretty fine with a spide. "it sliould be used 

 fresh, aud the border f^hould bo well drained, and in planting the ball of 

 encb should be loosened and tbe fresh soil worked in amongst the roots. 

 The soil should be made firm about the roots. They should be planted 

 rather high, as the soil will settle. Camellia Valtevaredo is a plant of fina 

 habit and foliage, haviug finely-formed rose-coloured flowers.

 plants, but some of them may be raised from seed. It is best, however, 

 to obtain plants. They all will succeed well in a rather shady situation, 

 but not under trees. 



Japanese Maize (Idem). — We presume it is the variegated variety 

 about which you iuquire. It attains to a height of 6 feet and more, and 

 is not, therefore, suitiible for edgings. It is very finely variegated, and 

 well worth growing. It requires a warm, sheUereU situation, and may be 

 used as a centre to a large bed, or at the back of a ribbon border, and it 

 requires to bo sown each year, and in heat, so as to get it strong beforo 

 planting out. 



Australian Spinach (Idem) — Itrequii-estobe sown in heat, and whea 

 strong planted out in good rich soil. 



Soiir;HUM tartaricum (f^f7n).— It is a taU-growing Grass, of no use in 

 our climate but as fodder for cattle. 



Cape Aster (Idcvi). — Cape Aster, or Agathfei (Cineraria) amelloidea 

 coelestis, is an evergreen, low-growing shrub, attaiuing to a height of 

 18 inches. It fluweis very freely; the flowers of a bright blue. It re- 

 quires to be wintered in a greenhouse; is raised from cuttings of tha 

 half-ripened wood placed in a mild hotbed. It cannot be raised in the 

 open border. 



Delphinium formosum {/dem). — The seed of this lovely bright blue- 

 floweriug plant may be sown now in an open border, and when tbe plants 

 are large enougli to handle they should bo pricked off in a bed of good 

 rich soil about 3 inches npart, and in autumn pl.Auted where they arc t» 

 bloom. Tbe seed may be sown in March iu a hotbed; tbe plants being 

 pricked off when large enough to handle, and grown on, wLI flower the 

 B.ime year. 



Six Select Perennial Phloxes (JdcTn).— Purity, white, carmine centre ; 

 Madame Tbibaut, crimson, dark centre; Picturata, rose, centre marked 

 crimson ; Mudamo Corbay, while, violet centre; Beatrice, carmine crim- 

 sou, and Madame Lemort, violet mauve, flaked with purple; another 

 good one ifl Triomphe de Twickle, carmine, edged white.
