THE ORCHID HOUSES. 



CYrUIPKDIl'MS.— C. Charh-sworthi will 

 be ill flower, or puhhing up its flower Kpike« 

 ^accordiiiff to the tonii>erature m which it 

 "has been grown. It is a rath<»r small and 



slow growing: npeeioH, but in very free m 

 producing flow<>rK wlien its requirenientfi are 

 proporlv understood. It succeeds best in a 

 bhidy position at tlio anA end of the inter- 

 mediate house. Like all ey ])ripediums, it ih 

 especiallv fond of moisture during the grow- 

 in^ season. After flowering the plants will 

 not be so active until February, therefore 

 tky should be kept drier during the winter 

 mouths, hnt should not be allowed to he- 

 come quite dry. Where this cypripcdium iti 

 arown in quantity, there wiW }ye found a great 

 diversity of form and colour amonjf the 

 flowers. The late autumn and winter flower- 

 ing cypripediums of the intermediate sec- 

 tion all bloom with remarkable freedom, 

 making them of special value during the dull 

 season of the year. No other orchids will 

 produce flowers in such abundance, or pro- 

 vide such a display at that season, and un- 

 doubtedly the great popularity these plants 

 enjoy is due to this, and to the length of 

 time the flowers last when cut. The section 



includes C. insigne and its nume>roufi var'e 

 ties, both yellow and spotted; C. insigne 



Sanderae is still amongst the best of the 

 former, and T. i. Flarefield Hall the best 

 of the latter. These are often recommended 



to be grown c<k)1, hut I have not yet seen 

 plants growing satisfactorily und'^r tfiese con- 

 ditions the whole year round. They delight 

 in an inti>rmodiate house temperature at all 



times. 



SEKDM N< . >. At thr present time it is 

 undoubtedly the ambition of everyone who 

 cultivates orchids to raise ^ee<llings, and, as 

 cypripediums are the easiest of all to succeed 

 with, many start with them. The present is 

 a suitable time to re[>ot seedlings that have 

 become root-bound, or require new rooting 

 material, the general atmospheric condi- 

 tions being favourable to root action. Small 

 seedlings may also be removed from the seed 

 b^^ds, placing; several together in ^mall pits. 

 For theso the rooting material should con- 

 sist i){ ('([ual jiarts of peat fibre from which 

 the line particles have been taken, and 

 sphagnum moss. Place the soil moderately 

 firm in the pots, and to encourage the small 

 HoedlnHTs to tiikv root -hold (|iurklv and

 the leading shoot when strong enough. 



CLKKODKNDIJON UAhFOlJUI — Whether 

 grown (»n the roof or pillars of the stove, or 

 ou a trellirt in pots, the ])lants should have 

 all calycevi pruned away as they fade; also all 

 weak shootri should be shortened in order to 

 concentrate the energies of the plant on the 

 development of the stronger growths, which 

 will produce flowers next year. No time 

 should be loeit in placing them in a ]M>sition 

 where they w^ill receive the maximum amount 

 of sun and air before going to rest. Allow 

 the plants to become on the dry bide before 

 applying water, and then give only sufficient 

 to keep the w^ood plump. 



OTHER CLIMBERS, such as allamandas, 

 stephanotis, bougainvilleas, and dipladeniae, 

 require similar treatment at this sea*^on to 

 ensure ripening of the wood, w^ithout wiiich 

 a wealth of flowers cannot be expected next 

 vear. 



* PLANTS IN COOL HOUSES.— Many occu- 

 pants of plant stoves will bear a few week's 

 sojourn in the conservatory in the majority 

 of summers, but this year great care will 

 have to be taken not to leave them too long, 

 unless the structure is kept heated, or the 

 plants will suffer much injury. Generally 

 speaking, it is better not to risk them in 

 such structures in seasons when the prevail- 

 ing temperature is much below the average.

THE FLOWER GARDEN. 



HEATHS.— Many of these are making a 

 ^howy display, and, when naturalised in 

 large, irregular masses on rough banks and 

 other open spaces, they create a pleasing fea- 

 ture. When once established they require 

 little attention ]>eyond weeding, and having 

 the long, straggling growths shortened back 

 after flowering. The various hardy ericas 

 oan bo planted during the autumn and 

 winter months, and they are not so particu- 

 lar alwut soil as is sometimes imagined. It 

 is important to thoroughly cultivate the 

 ground for their reception, and to let it 

 settle down well before planting. Win re 

 the soil is heavy and retentive, incorjx)ral(' 

 a lib.'»ral suiioly of leaf-soil and coarse sand

can either be placed in a cold frame or in 

 boxes filled with a light, sandy cx)jn]K>st. 

 (Jive a good watering with clean water, and 

 syringe them over on bright days; also keep 

 the frame clow^ until the cuttings are rooted. 

 Later on they must be carefully protected 

 from frost. Violas* are readily propagated 

 in the same manner, and will r<K)t easily if 

 carefully treated. \Vhen it is desired to in- 

 ciease choice varieties it is an advantage to 

 pot up the old plants, from which cuttings 

 can be obtained in the early spring. Do all 

 that is possible to keep the herbaceous bor- 

 ders gay and attractive bv removing dead 



flower stalks, and keeping the later flowering 

 bjectfl well tied. Delphiniums and herba- 



phloxes can be increased from cuttings 

 inserted now, and rooted in a cold frame. 

 Subjects like pyrethrunis can l->e lifted and 

 divided when it is necessary to increase the 

 stock. Cuttings of roses will root readily in 

 the open ground at the present time if in- 

 serted in soil containing plenty of coarse 

 sand — J. Gakdnee. Batsford Park Gardens. 



FRUITS UNDER CLASS. 



LATE GRAPES.— It being es^^ntial that 

 the berries of late grapes should be well 

 coloured by the end of this month, plenty of 

 air should^ be admitted to the house night 

 and day. When the weather permits, arti- 

 ficial heat can loe dispensed with on bright, 

 snnnv davs, but durinsjdnlj. snnkv^s w<\atber. 

 and at night sufficient luat mu^t Ik^ umhI to 

 maintain a fairly dry atmosphere. (iive 

 copious supplies of w^ater to the roots a^ r<'- 

 quired, w^ith occasional applications of licjuid 

 farmyard manure. This oj>eration should >>e 



done early in the morning, .so that the 

 atmospheric conditions of the house may ])o- 

 come fairly dry tefore night. l*ine]i all 

 lateral at one leaf, and do not on any ac-
