80 ORCHIDS : HOW TO GROW THEM SUCCESSFULLY. 



November, 



Cool House. — Temperature, day luith sun, 63"; day luithout sun, 

 08 ■ : night, 55" : morning, 50". 



With repotting and top dressing finished, watering of the 

 plants must be done with care, giving only to those which may 

 still be making a httle growth, and only now and then to the 

 inactive, sufficient to keep them plump. Now that so little time 

 will have to be spent in watering and damping down, for once or 

 twice a day for damping wdll be sufficient, according to the fire 

 heat in use, there will be plenty of time for a general cleaning up, 

 washing the pots, thoroughly cleaning the plants, and destroying 

 any insects that may be discovered in their hiding places ; the 

 woodwork, glass, and stages must also have attention, clearing 

 away all dirt and rubbish, whitewashing the walls, and making all 

 snug and clean. 



Orchids producing flower spikes should be raised above the 

 others by using inverted flower pots, so that they may be easily 

 watched and protected from slugs and other enemies. 



Intermediate House. — Temperature, day ivith sun, 65° to TO"*; 

 day witJiout sun, 68" ; night, 58" : morning, 55". 



With increased fire heat now, see that the atmospheric conditions 

 of the house have careful attention. Damp, murky weather at this 

 time of the year should be counteracted by just sufficient warmth in 

 the pipes and house to allow the air admitted through the top and 

 bottom ventilators, both night and day, to be warmed and circulated, 

 unless the outside air is too cold or there is the certainty of frost. 



In towns where smoke prevails and when there are fogs, it is 

 best to exclude the outside air at such times, seeing that the plants 

 and atmosphere are not over dry. Afterwards well wash the glass 

 to remove all dirt and to obtain all the hght possible, also go over 

 the plants with a sponge to remove the soot, &c., that is deposited 

 on the leaves. 



Warm House. — Temperature, day with sun, 70" to lo" ; day without 

 sun, 65" to 70" ; night, 65° to 70" ; morning, 65". 

 Now that more fire heat will be needed, see that the atmos- 

 phere does not become too dry and arid, and damping down about 

 twice a day. Let any cleaning up also be attended to here, as in 

 the other houses.
