rich or retentive of moisture, the plants are very subject to 

 die suddenly, when in full vigour. 



In summer it should be placed in a cold frame or pits 

 where the lights can be removed entirely in dull weather and 

 at nights during summer, but kept on during boisterous and wet 

 weather. It is a mistake to suppose that greenhouse plants 

 should be placed out of doors and subjected to all the vicissi- 

 tudes of the weather during summer. As regards delicate sorts 

 like the present, the sudden changes which they are subjected 

 to when placed out of doors are very destructive to them ; they 

 should be kept in as small pots as possible, and placed in an 

 airy cool part of the green-house where there is plenty of light 

 during winter, but where there is no danger of sudden 

 changes in the temperature, by fire-heat or neglect of water- 

 ing. More injury is done by too much fire heat and too little 

 water to such plants during winter, than by all other causes 

 together, frost alone excepted.
