‘till they get well established again. The back bulbs that were cut off can 
‘be placed together in pans, with a little sphagnum moss, and placed in a 
‘warm house, where they will soon make new plants. 
DENDROBIUMS, with the exception of such varieties as albosanguineum, 
amcenum, Bensoniz, moschatum, pulchellum (Dalhousieanum), X Dalhou- 
‘nobile, and other late blooming varieties, will now have finished flowering, 
-and should be repotted as recommended in last month’s Calendar. They 
should be grown in a temperature of not less than 80°, and require but very 
little ventilation till the growths are nearly finished. They should have all 
‘the sunlight possible without being allowed to scald. Keep the house well 
‘saturated with moisture, and spray the plants overhead several times daily 
‘with clean soft water, which should be placed in the house long enough to 
get warm before using. The point to have in view in successfully growing 
Dendrobiums is to get the young bulbs made up early in the autumn, so 
‘that they can be properly ripened up before the dull short days arrive, after 
‘which it is impossible to ripen them satisfactorily. If not properly ripened 
the grower is greatly disappointed to find when the flowering season comes, 
‘that, although he has fine bulbs, they fail to flower, and this I think is one 
-of the chief reasons why many people give up cultivating them. 
MILToNIAS.—M. vexillaria and its varieties are now pushing up their 
flower spikes, and should have copious supplies of water. They should be 
dightly fumigated every week till the flowers are open, so that they may be 
‘free from the little yellow thrips which are so often very lively on Miltonias 
-when about to flower. At the end of this month the plants should be placed 
at the warm end of the Odontoglossum house, where they can remain till 
the autumn. 
ODONTOGLOSSUM CITROSMUM may now be given water, as all that will 
flower this season will now be showing their flower spikes. Give the plants 
-a good soaking, and then treat them in the ordinary way. Care should be 
taken to keep the water away from the young growths. Any plant requir- 
ing repotting may now bedone. We use a compost consisting of half each 
of sphagnum moss and peat, and pot firmly. They should now be 
suspended in the Cattleya house for the growing season. 
TRICHOPILIAS.—Many growers fail to grow this very pretty and interest- 
- ing class of Orchid satisfactorily, and I think many give them too much 
heat during the summer. They should now be placed in the Intermediate 
house and not overwatered. They should be kept just moist, except when 
they are making new growth, and then they can have a little more water, 
but should never be saturated. A suitable compost for them consists of 
half each of peat, or Osmunda fibre, and sphagnum moss. They should 
be grown in shallow pans, large enough to hold them comfortably, and 
potted firmly.
