212 THE ORCHID REVIEW. 
CALENDAR OF OPERATIONS FOR JULY. 
By H. A. BURBERRY, King’s Heath, Birmingham. 
WE must make the best use of the summer weather, so that our Orchids 
may grow freely while we have the means at hand to enable them to do so. 
Do not starve them for want of moisture ; at the same time give them 
plenty of light and sun by removing the blinds as early as all danger of 
burning or scalding is past, and give enough air to keep the atmosphere 
fresh and pure. It will now be undesirable to make a wide difference 
between the temperature of the Cattleya, Lelia, and East Indian Houses. 
If, however, many of the cooler growing Orchids, such as Odontoglossums, 
Oncidiums, Cypripediums, Masdevallias, &c., are growing with the Cattleyas 
and Lelias, then of course it is most desirable that a difference in the 
temperature should be effected, in order to suit the better the last-named 
species. | Many growers are doubtless inconvenienced in this respect, their 
love for Orchids causing them to get a large number of various species 
together, which must necessarily grow together in the same compartment 
owing to want of room. 
It is in such instances where the cool pit, or frame, having a northern 
aspect, is of immense value to them; because then their cool Orchids 
proper may be placed there as soon as the summer weather has 
become somewhat settled, which this year was rather late. No doubt 
there are many species which delight in the frame treatment during the 
summer months; that is, supposing they are properly shaded from the hot 
sunshine and other due attention given. The frame should be raised 
sufficiently high to allow of a temporary stage being placed therein, a foot or 
so from the ground floor, on which to stand the pots. There are a large 
number of Orchids that may be so grown during summer, comprising the 
whole of those species commonly known as Cool house Orchids. 
The East Indian house Orchids are now doing their best, the warm 
weather of the last few weeks being greatly appreciated by them. The 
Phalznopsis are bristling with new roots. It is quite useless to try to 
confine the roots of these and other such air-rooting Orchids to the basket 
or pot in which they grow. In fact, to attempt to do so results more 
often than not in the deterioration of the plants: they resent too much 
meddling with. All that Phalenopsis require—together with Vandas 
Saccolabiums, Aérides and Angrecums—is to be made secure in some kind 
of receptacle, either for suspending or standing on the stages, as the case 
may demand, after which the roots should very rarely be disturbed, but 
allowed to ramble about at their own sweet will, keeping them more or less 
supplied with moisture, in accordance with the season of the year, by 
syringing them with tepid water.
