Novemper, 1913.] THE ORCHID REVIEW. 355 
CALENDAR OF OPERATIONS FOR NOVEMBER. 
By J. T. Barker, The West Hill Gardens, Hessle, E. Yorks. 
SINCE writing my last the weather has taken a great change, and from 
clear, bright skies we have had a quantity of rain, with its accompanying 
clouds, and already we are experiencing quite dark and dismal weather. 
This is not to the benefit of the plants, and every effort should be made to- 
admit as much light as possible to the houses. Where the roofs of the 
houses are hung with plants to a considerable extent some re-arrangement 
will be necessary, so that those suspended from the roof do not impede the 
light reaching those placed upon the stages. 
TEMPERATURES.—The figures given last month for all the departments. 
should be continued, so there is no reason to repeat them. If any difference: 
is made it should be a slight reduction towards the minimum, or winter 
temperatures, as given in the Januafy number. It is not wise to drop- 
the temperatures all at once, or at any given time; a little discretion is- 
needed, and should we experience a spell of mild, humid weather it will be 
advisable to maintain the temperatures, and admit more air. Fresh air, if 
properly admitted, never does harm ; it is draughts which do the mischief. 
ATMOSPHERIC MOISTURE.—With the gradual reduction of temperatures, 
a corresponding gradual reduction of the amount of moisture in the 
atmosphere is necessary. No definite rule can be laid down, as the 
different houses vary considerably as regards their humidity. 
VENTILATION.—The admission of air will, during the present month,. 
need a great deal of attention, but, whenever practicable, fresh air must 
be admitted. This fact by present-day cultivators is much more practised: 
than formerly, and as time goes on is likely to become universal. Orchids. 
are not coddled to the extent they were formerly. 
WATERING is a matter which must be done carefully at this season. 
Those plants which are in growth will require comparatively little, and 
should be allowed to become dry before having it applied to them, whilst 
those at rest will only require sufficient to keep them plump and healthy. 
If at any time there should be a doubt as to a plant being sufficiently dry 
to require water, let it remain until you are quite certain. Many Orchids. 
are overwatered during the winter months, and receive an insufficient. 
supply during the summer when in full growth. 
STOKING.—During the present month this essential detail will require- 
considerable attention, as upon the amount of care bestowed depends the 
healthy or unhealthy surroundings of the plants. Too much fire heat is as 
detrimental to plant life as too little. Stuffiness in the houses must always. 
be avoided, a nice buoyant atmosphere, without too much fire heat, is the: 
ideal condition.
