JUNE, 1913.] THE ORCHID REVIEW. 181° 
CALENDAR OF OPERATIONS FOR JUNE. 
By J. T. BARKER, The West Hill Gardens, Hessle, E. Yorks. 
THE temperatures given for last month will still hold good, likewise such’ 
details of general management as the ventilation of the houses, watering 
the plants, and the amount of atmospheric moisture. Shading must not be- 
neglected whenever the sun’s power demands it, as plants are seriously 
disfigured, if not killed outright, when allowed to become scorched. Owing: 
to the sunlessness of the past two months the climatic conditions have not 
been favourable to Orchids, therefore as the plants start every inducement 
should be given them to produce healthy and robust growths, for it is much: 
easier to keep a healthy plant growing than it is to bring an unhealthy one 
back to the normal condition. 
FLOWERING PLANTS.—During the summer months it is good practice to 
place all plants that are in bloom in a house where the conditions are slightly 
drier and cooler than the one in which they made their growth, as there is- 
less danger of the flowers becoming spotted and ruined by excessive moisture. 
Where the number of plants grown will not allow of a house being thus- 
Set apart, the driest and coolest position should be selected for those in- 
loom. 
CATTLEYAs.—Amongst those which are in flower at the present time are 
C. Mendelii, C. Mossiz, and their innumerable hybrids. C. Trianz and C.- 
Schroederze, with their hybrids, are commencing to make new roots, and 
Should the compost show signs of exhaustion fresh materials should be- 
given. These plants are as easily grown as any others, provided a few 
simple details are followed. The first is to keep them in a sweet and 
healthy rooting medium; the second to repot them at those times when: 
they are producing new roots, and the third to water very sparingly after’ 
repotting, as no plant will root freely into a saturated compost. If 
thus treated they soon re-establish themselves in the new material, and- 
receive the least check possible. Another reason why Cattleyas do not 
thrive in many places is want of air. The atmosphere should be kept- 
buoyant at all times, as a stuffy house is detrimental to them. Lastly, they 
delight in abundance of light, but are not capable of withstanding strong. 
sunshine. 
Plants of C. Warscewiczii (gigas) that are now making strong growths,- 
and showing their flower sheaths, should have abundance of light and heat, 
and be supplied with water whenever they become dry. This plant, owing 
to its short season of growth, should receive generous treatment after 
growth commences, or it will not develop strong pseudobulbs, and it is folly, 
to expect flowers from weak ones. Plants in bloom and those that have- 
not made flower sheaths will greatly benefit by being placed under the:
