102 GARDENING FOR PLEASURE. 



2)etalums in peat and loam, and a little rotten manure ; 

 PhalcBnopsis, Yanclas, and Lcelias do well in baskets, 

 pots, or small pans, in chopped sphagnum ; the drainage 

 must be perfect. Calanthes, chopped sods of sandy loam, 

 with not over-fine leaf mold. The plants must be made 

 steady with stakes and copper wire. 



The kinds suited to grow on bark or cork, or other 

 such material, are Cattleyas, Lcelias, Phalcenopsis, Van- 

 das, and Dendrobiums. These all do well on blocks of cork, 

 rafts, cylinders, etc., with sphagnum or other moss ; but 

 take more care, as they dry so quickly. A plant on a block 

 v^ill take water twice a day ; the same in a basket only 

 once in two days. Blocks can be hung overhead, and 

 dipped twice a day in hot, dry weather. 



The temperature should be, for such varieties as PTia- 

 Icenopsis, Vandas, DendroMitms, and Cypripediums, in 

 winter, sixty to sixty-five degrees at night, to sev- 

 enty-five degrees by day, with air ; in summer, seventy 

 degrees at night, ninety or more degrees by day, with 

 plenty of air and ventilation at night. Cattleya, Lcelia, 

 Pliaius, Calanthe, Cmlogyne, and Zygopetalum, in winter, 

 fifty-five or sixty degrees at night, seventy degrees with 

 sun by day; in summer, sixty-five degrees at night, 

 eighty-five degrees by day, with plenty of air. Odonto- 

 gJossums, in winter, fifty-five degrees at night, sixty-five 

 degrees by day ; in summer, as cool as they can be kept. 

 All want abundance of atmospheric moisture night and 

 day. 



Some kinds, such as Phalcenopsis and Vandas, grow 

 at all seasons ; Cypripediums, Cattleyas, and Lcelias in 

 spring ; Calanthe, Coelogyne, Phaius, and Zygopetalums 

 in summer. When any plant grows in winter (except 

 Odontoglossums) it should be placed in a warm house. 

 Odontoglossums do best at a temperature of fifty-five to 

 seventy degrees ; never hotter, if possible.
