132 THE ORCHID REVIEW. [June, 1918, 
CALENDAR OF OPERATIONS FOR JUNE. 
By J. T. BARKER, The West Hill Gardens, 
Hessle, E. Yorks 
HE recent warm and bright weather has been favourable to the culture 
of all Orchids, and good progress has been made, especially by those 
grown in the warmer divisions. The details of management as regards 
temperatures, watering, ventilation, and atmospheric moisture laid down 
for the growing season may be continued for some time onward. During 
spells of bright weather, such as we have recently enjoyed, the temperatures 
cannot reasonably be kept too humid, but should a spell of wet and cloudy 
weather prevail, much less damping down is necessary. One should aim at 
a moist, buoyant atmosphere in every department, and whenever the houses 
become dry they should at once be damped down. At this season there 
will be an abundance of flowers, and even the most modest collections will 
be interesting. 
CATTLEYAS AND ALLIES.—C. Warscewiczii (gigas) will now be in active 
growth, and should occupy the lightest position in the house, and have 
liberal supplies of water. The earliest of them are already showing the 
flower sheaths, and in some cases the flower buds are pushing up the 
sheaths. The later ones will have the sheaths formed in the growths, that 
is if they are strong enough to flower this season. Withholding water after 
this date, as an inducement to the plant to flower, is a practice not to be 
recommended. C. Mossiz and Mendelii are now in full flower, also many 
Leliocattleyas, Brassocattleyas, and other hybrids which at this season 
make a gorgeous display. All that are in need of new rooting material may 
have attention as soon as they pass out of bloom. ; 
The general plan of repotting these plants soon after their flowerlns 
period is passed will be found quite satisfactory, provided the compost 8 
kept on the dry side until the new roots get active in the new material. In 
a group of plants as large as this one there is great diversity of form and 
character, both in the pseudobulbs and roots, and the latter characte! 
affords a guide as to treatment. Those having thick fleshy roots may Pé 
placed in larger receptacles than those with thin fibrous roots. The latter 
should be placed in small receptacles, as they have not sufficient energy '0 
push through a thick mass of material. In no class is it more desirable 
study the individuality of every plant than in this. At present it is m 
difficult to bestow sufficient attention cn the plants to obtain the best 
results, but to those who have the time this is a most interesting study, 
worthy of everyone’s consideration. | 
CALANTHES.— By this time the deciduous Calanthes will be well rooted,
