50 THE ORCHID REVIEW. [Marcu- APRIL, 1919 
Ordinary pots, of the smallest size possible, make suitable receptacles, and 
ample drainage should be given, so that the water passes speedily away. 
After repotting, the most critical time in the whole year may be experienced, 
especially should the weather be cold and damp, and it requires much 
discretion in the application of water to the compost at such times. In 
watering all plants with young tender roots, care should always be taken 
that the water is of the same temperature as the house. 
Decipuous OrcHIps.—Calanthes, Thunias, Cyrtopodiums, and other 
deciduous plants, will at this season need attention as regards repotting. 
Good fibrous loam is the chief element of the compost, and it is essential 
to these heat-loving plants that it be warmed before being used. Whilst in 
growth, they require plenty of heat and moisture in the atmosphere, and 
water must be applied with extreme care until the plants are well rooted, | 
after which plentiful supplies may be given. Calanthes should be potted 
firmly, whilst Thunias require a compost which their succulent roots can 
easily penetrate. ; 
PHAaIUs.—When these plants have finished flowering, and their young 
growths have got nicely away, any necessary repotting should be under- 
taken. They require a compost in which good fibrous loam may be the 
predominant partner, but the plants thrive in almost any compost, pro- 
viding it is porous, and water is applied discreetly. 
MILTONIA VEXILLARIA and its hybrids will now be pushing flower spikes 
from the partly developed growths. While in this condition, the plants 
should be watered whenever they become dry, and after the weather 
becomes mild they may be placed in cooler quarters. The warm end of the 
‘Cool house or a cool position in the Intermediate house will provide 
‘suitable quarters for them during the summer months, where they will make 
a display for a considerable time. Before the plants commence to open 
their flowers, it is a good practice to thoroughly cleanse them, to obviate 
an attack of thrip and other insect pests whilst they are in’ bloom. 
ODONTOGLossuMs.—Many of these plants that were not in a fit condi- 
tion to pot in August or September will be ready for potting now, that is 
if the young growths have attained sufficient length and are about to push 
new roots. All those in need of new material may be done, using a compost 
of two parts good fibrous peat, one part Ar fibre, two parts sphagnum 
moss, and one of broken leaves, with some small broken crocks added. 
Where considerable numbers of these plants are grown, some will be sure 
about three inches high is the proper time to repot Odontoglossums, 
irrespective of season. At the present time there are, in many collections, 
home-raised hybrids, and those that have passed through the winter in 
‘small pots will receive considerable benefit if carefully shaken out and given
