2i6 ORCHIDS FOR EVERYONE 



NOVEMBER 



Keep the roof glass clean. In smoky districts and in towns 

 the roof glass should be washed down once a week during Novem- 

 ber, December, and January. See that the roof is water-tight 

 before commencing the work, and apply the water so that it is 

 not forced upward under the laps of the glass. 



Scarcely any potting is necessary in November, and the prin- 

 cipal work among Orchids will consist in managing the heating 

 apparatus, and cleaning the plants and houses. 



Put slender stakes to the flowers of Cypripediums, and afford 

 neat ties. 



Keep a sharp lookout for slugs, tiny snails, cockroaches, and 

 other pests. 



Ccelogyne cristata, Dendrobium nobile^ D. aureum, and D. 

 Wardianum may be placed in a warmer house if flowers are needed 

 for Christmas and the new year. Only a few plants should be so 

 treated, and these the most advanced. 



Some late-flowering Cattleyas may need to be potted, such as 

 C labiata^ C. Doiviana^ C. Hardy ana^ etc., and if they are making 

 new roots they must not be neglected in this respect. 



DECEMBER 



When the flowers of Winter-flowering Cypripediums have 

 fully developed, they should not be allowed to remain on the plants 

 until they fade, as this imposes a severe strain. They will last a 

 long time in good condition if cut and placed in water.
