THE ORCHID REVIEW. 171 
CALENDAR OF OPERATIONS FOR JUNE. 
By W. H. Younc, Clare Lawn, East Sheen. 
By the time this appears in print we may safely assume that fire-heat will no 
longer be required in the Cool and Intermediate houses, and, given typical 
summer weather, very little will be needed in the other houses, though the fires 
should always be kept in, and a gentle circulation of heat maintained in the 
pipes of the Phalenopsis and East Indian houses. It should also be 
employed at night in the Cattleya house, to drive away surplus moisture, 
and also that more air may be admitted through the bottom ventilators. 
Plants in bloom should be kept moderately dry, excepting where root action 
is vigorous, as will probably be the case with such species as Cattleya 
Warscewiczii (gigas), Warneri, and Schilleriana. 
It is a practice in some establishments to have a house or compartment 
set aside for the display of Orchids when in bloom, but, except in very few 
instances, the removal of plants from their growing quarters is generally 
attended with injurious results, which, unfortunately for the grower, are not 
immediately apparent, and consequently it is difficult to convince the owner 
that such is the case some months after their return. There is one thing to 
be said in favour of their removal, and that is, there is a better chance of 
giving those left behind a more generous treatment, for where there are no 
flowers to be studied, damping and syringing may be carried out more 
fully than it could be otherwise, if we have any regard for the bloom. 
There is little to add concerning the cool Orchids to what was treated of 
in last month’s Calendar, excepting that on dry, hot days the plants may 
be sprayed overhead morning and afternoon, always taking the precaution 
to use clean water, or a sediment will be deposited on the leaves and flowers. 
The Disas should now be in a frame, situated in a cool and shaded spot, 
and syringed frequently, to keep the surrounding atmosphere moist. Bletia 
hyacinthina may be stood outside in the open, but kept well supplied with 
water. Thunias also, after they have flowered, may, about the end of the 
month, be placed in a sunny position outside, to ripen their newly-made 
bulbs. Those bulbs that have not produced flowers will, if kept in heat, 
continue growing almost indefinitely, but by placing them outside they finish 
up their growths, and become well matured, and thus be better able to go 
through the long resting period without rotting off. Of course, abundance 
of water must still be supplied right until they are taken in at the end of 
the summer. 
Anguloas flower in May and June, and should, if needed, be repotted 
immediately the blooms are removed. Being strong and vigorous-growing 
subjects, fairly large pots are required for their accommodation. These 
should be about two-thirds filled with drainage, and the compost used should
