TO CORRESPONDENTS. 



••• We request that no oue will write privately to the depart- 

 mental writers of the *' Journal of Horticulture, Cottage 

 Gardener, and Country Gentleman." By so doing they 

 are subjected to unjuHtifijible trouble and expense. All 

 communicationfl ehnuld therefore be addresfied sohhi to 

 The Editors of the Journal of Hortic'ilture, <£c., 171, Fleet 

 Street, London, E.G. 



We alao request that correinondents will not mix np on the 

 same sbeet q-iestions relatinfi to Gardening and those on 

 Poultry and Bee aabjects, if thoy expect to get them an- 

 swered promptly and 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 



Ha WKiMO Plants in Pots [T. 71.).— If a person hiwkinp plants in pots 

 travels with them fn.ra town to town, or calls at people's houses, he re- 

 qnires a banker's license. 



V Ti°i'^ ^^^'^"■^■* ' ^- fl"- H'.).— We cannot Rive nn opinion without Peeing 

 Doth kinds of leaves; nor can we naino Beans which we have never 

 seen. 



Vines SvRnJGnfG and Stopping [G. H.).— As the Vines are now in 

 their fitnninR stsjfe, you oucht to keep the floor<i. walls, and flues moi^t 

 by Bpnnkling them with w.ver twice a-day at least, and three or four 

 times would not be too often on verv hot drtvp, np to the time of the 

 GrapcH changinp colour, wh^n sprinklinK ehouM be discontinued. We 

 lear yon have in the " many bunches covered with poraethini? like dust " 

 toe mildew, but that we could not determine withoat a Ppecimcn. The 

 remedy for that U to dust with flowers of sulphnr. The Phoots ought to 

 be kept stnppt'd to within a few k-avos of th« bunch, not aliowint? them 

 to ramble until the Gnipes have swelled off. Enouch leaves should be 

 left to shield the bunches from too ptwerful sun, and to elaborate the 

 sap. It is well to have a moderate amount of foliasre. but do not allow it 

 to ramble and then reduce it wholesale. We cannot name plants from 

 leaves only ; flowers are neccssarj*. 



Orchard-house Covstructing (ff 77. B.I.— Thesituat'on. wepresnrao, 

 18 open, and has the sun's rays all the dav, without ob«trnction from 

 bmldings or trees. The sides nnd ends will answer well, formed of 

 boarde. toneued and grooved, and put together verv closelv. The upper- 

 most but one may be hinged for ventilation. It should bo 11 inches 

 wide, and marie to open the entire length. A span roof would be best, 

 and yon could havo the hoards bing- d at both sHes, and that would give 

 sufficient ventilation. The boards nei;d only be dressed on the side whi<^h 

 18 towards the interior of the house. Th*j ontside being rough, may b« 

 coated with boiling coal tar, but the t^mooth surfacn may be painted with 

 white lead. If the house be a lean-to, there should bo openings for ven- 

 tilation nt bnck, immediately under the wall plate, as well as the hinged 

 board in front. We presume you do not intend to still use the house as 

 a poultry yard. 



pRACANA Leaves Bhowjted fJn-a-Fij).— By keeping them shaded yon 

 will secure a more equable temper iture, and -he leavL-s will not spot or 

 become browne * at the tips ; but in the eha-io they will he of bad colour. 

 We do not syrince onra at all, but give them a light and airy po-ition 

 and abnndance of room. We admit a little air early so as to dissipate 

 any moisture condens'td on the leaves during the night, and havo the 

 foliage dry bi-fore the snn shines powerfully upon them. The atmosphere 

 should be kept moist by frequeutly s .rinkling the floor, wal s, &c. To 

 have the idauts in good colour for winter they should at once hnvo light, 

 as those now formed green will to a (jreal extent continue so The more 

 light sueh plants have, the better coloured they will be ; but if shaded 

 they will grow more, and not bo so liable io become brown, or go off at 

 the tips of the leaves. 



Coldstream Early Potatoes (.4 Simnle Seot).~Ynn are qnito correct 

 in stating that this very closely resembles Smith's Early. It is rather 

 superior, bat should bo sold for aborit the same price. 



Horseradish Leaf (Mrs. Whit').— The white spots are a parasitic 

 fungi of a genus occurring on tho dead and decaying leaves of the 

 Cocblearias 



Guano Water PnoDccrxo Green Fly (John B.).—It will not induce, 

 but rather act as a preventive of green fly. 



Pelaroonicms after Flowering (Id^m).— Place them out of doors in 

 a slightly-shnded position, supplying them with water ns required, but 

 not so much so as when growioii, and yet not allowing tho folLigo to flag. 

 Prune in August, and in September place them in a cold fr«iiie, setting 

 the pots on cnal ashes, and give no m'lrc water than enom.'h to keep tho 

 Boil moint ; protect from heavy rain-*, but admit air by tilting tbo lights. 

 When they have shoots an inch long, shako the plants out of the pots, 

 and repot in others no larger than sufUcleot to hold the mots properly ; 

 return the plants to the frame, keeping it rather close and shaded for a 

 few days, then expose them fully to light and air, protecting, however, 

 from heavy rains. At the end of September or the beginning i>f October 

 remove them to a shelf in the greenhouse, whore they can have abun- 

 dance of I g'lt and air. 



Roses after Forcing fJd'm).— Plunge the pots in coal ashes quite to 

 the rim. and give tho plants plenty of room. The situation should be 

 open and w ir n. Supply them well with water, in September repot, and 

 at the end of October remove them to a cold frame, plunging the pots as 

 before, and admitting air r»n all fitvourable occasions, btit protecting from 

 heavy rains and eevere frosts. During tho latter, a covering of mats in 



Addition to the lights will be de«irab1e. Prune fn November or Heeember. 

 The plants mnv be taken from the frame as ruc|nired, and placed In the 

 greenhouse or forcing pit. 



PiOEOMs' DcNO {A Subtcrib/-r).— It is not so powerful n manure M 

 gnono, but i*t. n.'vortheies«, one of th« beht manures, and niiv bo safely 

 used to all kinds of flowers, fruit 'r-es, and vegetnhUs. It 'should be 

 thoroughly mixed with an equal quantitv of .irv sod, and atored in a 

 phed where it will bo kept dry. Uv being laid thinly, turned over fre- 

 quently. It is kept from heating, as when it heats, as it will do if laid 

 thickly, its fertilising constituent. amuKUia. is to a great extent lost. 

 About 1 inch in tulcknetifl is a good dre^Rint.'. nnd may be nppUod now as 

 a top-dressing to tho ^.oil near Hose^ and fruit Ire* «. and ajain in March, 

 neatly pointing it in with a fork, if that can uo d.ue without injury to 

 the roots ; if, however, thoy aro near the surf-ire, it will be aumcient to 

 cover the manure with a little soil. For vegoLables It ehould be applied 

 previous to i»lanling and dug into the ground. 



ApntDEs ON RosK AND FariTTREKs (3frj(. O.).— There if. as Tousav, an 

 unusual abundance of these pests this ynar, owing, no doubt. t.» the pre- 

 valence of cold north-eatiterly winds. We do not know of a belter mode 

 of destroying Ihem thfin dipping the shoots on a dry evening in tobacco 

 water, which nmy bo obtained at anv tobacco maoubicturv, or it may be 

 made by pouring four gallons of boiling water on 1 lb. of the Btrongest 

 tobacco, covering up, and then the tot«acco should be strained and 

 squeezi'dsoas to express the juice. If tho ^hoot8 cannot be dipped in 

 the tobacco water, it may be Hpplied with a tine-rosed wntcring-pot or 

 syringe. There is another effectual mode of clearing off the aphides— 

 namely, to syringe the bushes on a calm evening, aud whilst wet dust 

 them with tobacco powder, giving the hashes a good syringing the follow- 

 ing evening. The bushes may be washed in autumn or winter before 

 the buds begin to grow, with a composition of 4 ozs. of goft soap to a 

 gallon of tobacco water, made from 4 ojts. of tobacco in a gallon of water; 

 adding enough sulphur vivom. soot, and a lum;iof lime, unslaked, about 

 twice tho size of a hen's egg to bring the mixture to the CLjnsistency of 

 thin paint, applying it with a t.ruih to all the parts of the ^hootB and 

 stems after pruning, rubbing it well into the angles and crevices of the 

 bark and stem, and taking care not to dislodge the buds. 



Select Roses {Ilcnn/ Bc(brrU, Lancathire).—" Cloth of Gold and Mari- 

 chal Niel are so precorioas, that I do not care to recommend them, but 

 they are tho finest of tho yellow Pu>spb, and would do wel under glass. 

 To your collection of seven Koses add these. They are free-blooming, 

 and sncce&Hful Roses here, and, in my judgment, they are the tliU. 

 Yellfitc : Gloire de Dijon* Triomphe de' E>-nnes, -i-liue' Forostier, and 

 Solfalorre. The last requires a S. or S E wall. For free and continuouB 

 blooming, no yellow Rose has a chance with it, good and excellent as are 

 tho two first named. liouc colour or Pink: Baronne Prevost, William 

 Griffiths, Gloire de Vitry, Comtesse de C< abrillant. John Hopper, Charles 

 Rouillard, Barou Gonella, Comte de Nanieuil, Princess Mary of Cam- 

 bridge, Paul Verdier, Monsieur Noman. JHiu<h : Abel Grand, Marguerite 

 de St. Amand. La France, Duchesso d'Orleans, La Strur des Anges, 

 Madame Knorr, Madame la Bnronne de R'ith?;child. a magnificent Rose. 

 White : Baronne de Maynard and Madame Alfred iie Rongemont. 

 DarkcMt Crimson, or Maroon: Prince Camillo de Rohl^n. Due de Cues, 

 Pierre Notting. Souvenir de Dr. Jamain. Bnronne Pellotan de Kinkelin, 

 Empereur do Maroc. Souvenir do W. Wool, Viromle Vigier. crtBUon, 

 Chrmj colour, or Carmine: Charles Lefebvre, Marie Bnumann. Alfred 

 Cidomb, Maurice Bcruardin, Lord Maciulav, Madame Vi-tor Verdier, 

 Senateur Vaisso, Kxposition de Brie. Dr. Andry, Lady Siiifield. Marshal 

 Vail'ant. Jules Mirgoitin, Madame Boutin. Baronne "Ad.lphe de Roths- 

 child, Midame Clemence Joigneaux, Duchf^sse do Caylus. Leopold Pre- 

 mier, Mad;ime Julie Daran, and Achillc Gouod. It la impi^isible to 

 speak tno highly in every respect of the two new Roses, M 'rie Baumann, 

 and Mmc. In Baronne de Rjtbschild. I have other new Koses here, bat I 

 will not speak of them, though I think some of them very promising, till 

 I cin speak confidently. If you wish for more white Rises. 1 recomtbend 

 the two Tea Roses, Madame Willermoz and Somhrenil. The latter is as 

 hardy as a Hybrid Perpetual, a ►trong grower, i^M continual bloomer. 

 Acidalie is fine, but probably it would not bloom freely in Lancashire. — 

 W. F. Radclyffe." 



Pueifyixo Air (O. S. if.).— You need be under no apprehension that 

 the air of Forest Hill is not suffi'^iently pure for Roses. We know where 

 they flourish mucj nearer London, and close to Manchester. Birming- 

 ham, and "beffield. If it were otherwise, there is no chemical that 

 would purify the air ns it eutered the Rose-house. 



Froth Ixsect {li. W.}.—U you remove the froth with a sponge yon 

 will find an insect within, which produces the froth. The insect is called 

 by oatomologists Tettigouia spumaria. and Aphrophora spumaria by 

 some. It is the larva which is inside the froth, and it should be de- 

 stroyed, for by its sb^irp rostrum or beak it extracts the sap of the plants 

 it infests, and voids it as an excrement in the frahy foam. 



Raisino Vxn'ES (Idtm). — You will not succeed very well in the open air, 

 but by making a frame and forming a hutbed, you may raiiiie them in 

 quantity. The wall might form the back of the frame, and yon would 

 only need a front wall and ends, making an excavation so as to allow for 

 fermenting material, which should bo at least 4 feet deep, and there 

 should be a height of 2 feet for the plants to grow in. The excavation 

 might be 6 feet wide or more, nnd any length. Fill it with hot dung in 

 the first week in March, and put in the eyes or cuttings in Sinch pote, 

 plunging them in sawdust, but the bottom bent must not exceed 90°. 

 The plants i^hould be potted in G-iuch pots when the smaller pots are full 

 of roots. The cuttings or eyes may be potted in February, and kept 

 rather dry until placod in the hotbed, and in July the pit may be emptied 

 partly or wholly, according as the plants grow, to give them head room, a 

 btick beitig placed in each pot to train the Vine to. If the Vine^ require 

 it, they may he potted in 9-iuch pots. They should be kept rather close 

 and well watered, but not excessively, so as to «-ncourage a good crowth ; 

 keep them dry aft r September, so as to ripen the wood. In the following 

 March they may be planted out where they are to remain, cutting tbem 

 down to two eyes. Another batch of eyes may then be started. The 

 Vines would not be in a bearing ntnte until the fourth or fifth year. We 

 shall 8l>ortIy treat of tho out-d<K>r culture of Grapes, or those agtUnst 

 walls, when your queries will bo more fully answered. Wo cannot say 

 whether you can grow Grapes profitibly on walls, .so muf^b depends on 

 the locality. In qnality they are nbuut equal to foreign Ortpes, and are 

 worth, when first-class, about Is. 6i. per lb. We have known them bring
