48 THE ORCAID REVIEW. [ FEBRUARY, 1903- 
of broken crocks. Keep the under sides of the leaves syringed during hot 
weather to prevent attacks of red spider, to which they are very subject. 
When growth is completed the plants should be rested in the Cattleya 
house, and less water applied to the roots. 
Dendrobium chrysanthum is now starting into growth, and delights in 
hot moist treatment. It succeeds well if grown suspended near the glass in 
teak baskets. Ifany of the plants require rebasketing or top-dressing it 
should now be attended to, giving plenty of drainage, and a compost of 
two parts sphagnum to one of peat. Water sparingly until the young roots 
have a ficm hold, or the new growths will probably damp off. When in full 
growth, however, liberal supplies may be given, until the growth is made 
and the flowers fade. The plant then will need a rest, and water should 
be given accordingly. 
In the Cattleya House C. Warneri will be starting into growth, and 
should now be given a position at the warmest end of the house, close to the 
glass, for all the light available is needed at this season. Give little water 
until growth is well advanced, when the supplies may be increased. An 
occasional drying of the compost will prevent it becoming sour, and also the 
old roots from decaying. When sufficiently dry give a thorough watering, 
and as the growths mature gradually reduce the amount until only enough ~ ae 
is required to prevent shrivelling. 
Odontoglossum citrosmum is a plant well worthy of cultivaticn in every 
collection, being of easy culture, and when in bloom makes a very effective 
display with its long pendulous spikes. Water should only be applied at 
the present time to prevent shrivelling to excess, or the flower spikes, which 
appear out of the young growths, will not be forthcoming. When these make 
their appearance more water may be given, and the spikes protected from 
woodlice and slugs by a piece of wadding wrapped round them. An 
excellent trap for woodlice will be found by cutting a potato in half, 
hollowing out the centre, and placing the pieces on the compost. These 
should be examined night and morning. 
Cymbidium Lowianum is now throwing out flower spikes, and will 
greatly benefit by the application of weak liquid manure occasionally. 
IMPORTED OrRcHIDs.—The success in establishing imported Orchids is 
largely due to the method of treatment given when received from the various 
importers. In the first place it is essential, before placing them in the houses, 
to thoroughly cleanse them from dirt and insects, afterwards laying them 
on a stage in a cool moist house until the potting can be done. They will 
keep in better condition if given this treatment, and kept shaded until the 
appearance of activity; the growth will be also stronger and cleaner when 
it begins.
