orchids: how to grow them successfully. T.'J 



pure as possible. Vontilato chioily on the leeward side, and use 

 shading during the hottest part of the day, but not too early in the 

 morning, and rolling up the blind rather early in the afternoon, 

 whilst the sun has houw, power, at the same time reducing the 

 ventilation and thoroughly damping down the house, thus creating 

 a warm and very moist atmosphere which ^vill last until late in 

 the ev(!ning, when it may be nc^cessary to have a little warmth 

 ill tlu! pipes to prc^veut too low a temperature. 



June. 



Cool House. — Temperature, day iviih sun, as low as it ran be kejjt ;. 



day without sun, also as low as possible luhen the iveather is hot ; 



night, 60" .• morning, bo" to GO". 

 Great inj ury will be inflicted on the plants during the summer 

 months, if allowed to suffer from drought at the roots. Examine 

 the plants each morning, and water those where the sphagnum 

 moss shows a whitish colour. Thiip breed rapidly at this season, 

 and, like all other insects, must be kept down by the methods 

 already indicated. Instances of over-heating now will be rare 

 when the plants have been properly potted, and the compost as 

 well as the plants are in good condition. 



Intermediate House. — Temperature, day unfh sun, 15° to 80' ; day 

 without sun, 73°; night, 6o° to 70"; morning, 65". 

 Plants will now advance very rapidly, and in all weathers the 

 plants must have every encouragement to promote quick growth 

 by giving liberal supplies of water at the root, and moisture in the 

 atmosphere of the house, and this can be easily seciu-ed by damping 

 down frequ(!utly provided proper ventilation secures a gentle circu- 

 lation of fresh air. A fresh supply of tree leaves saved from last 

 year should be placed under the stages over the pipes, and watering 

 now should be done in the afternoon or evening. Cattleyas, and 

 indeed other Orchids, often have a little shrivelled appearance after 

 flowering, but soon regain vigour and plumpness mth liberal treat- 

 ment. Be sure and keep a sharp look out for the Cattleya fly. 



Warm House. — The temperature same as in May. 

 Warmth from the sun is most beneficial to the plants at all 

 times, and but little fire heat may now be used, except dming cold 

 or chilly dull weather. Keep a sharp look out for the Dendrobium
