THE GREEN-HOUSE. 



dead leaves must be picked off as they appear ; all 

 weeds pulled out, and any holes or derangements, by 

 watering or other causes, in the surface of the pots 

 filled up with fresh earth. 



During dry weather, watering will have to be per- 

 formed every day ; the best time is the evening, and 

 the safest plan is first to supply all the pots accordixig 

 to their wants, and then, if the weather is not more 

 than usually cold, to syringe them over their tops. 



Sect. IV. Management of Green-house Plants in 

 Autumn. 



The principal autumn operation is that of return- 

 ing the plants to the green-house. This is generally 

 done in the course of the month of September, com- 

 mencing with the more tender Cape and South-sea 

 plants, and ending with the more hardy species of 

 the South of Europe. 



Green-house plants are never shifted at this sea- 

 son, as it is not intended, or desirable, that they 

 should continue growing during the autumn and 

 winter months. Some plants, however, from disease, 

 worms, the pot breaking, or some other accidental 

 cause, may require to be fresh potted, and most of them 

 will be improved by refreshing their surfaces with a 

 little new mould, first removing the caked or mossy 

 surface crust, and then stirring and incorporating it 

 with what is below. 



Those plants which have stood above the surface.
