WATERING TEMPERATURE. 



If their growth is checked from any cause, they 

 should be carefully watered. Very likely, nearly all 

 the roots are destroyed, and they cannot use much 

 water until new ones are formed. It should be re- 

 membered that plants in porous pots require more 

 water than those in metal or glazed vessels, as it 

 evaporates through their sides. 



Watering should be done at a regular hour and 

 in the early part of the day, to provide plants ex- 

 posed to a hot sun, with a plentiful supply of mois- 

 ture at their roots. On cloudy or rainy clays, they 

 will need less, and perhaps none at all. Plants in 

 porous pots surounded by sand require water but 

 two or three times a week. 



Care should be used not to wet the foliage of 

 rough leaved plants, as the Begonia or Chinese 

 Primrose. 



TEMPERATURE AND ATMOSPHERIC MOISTURE. 



Extremes of temperature, as permitting plants to 

 get too cold at night, and too warm during the day, 

 have a tendency to check their growth and induc e 

 disease. Window plants are most frequently 

 injured by too much heat. For a general collection 

 of plants, a temperature that ranges from 60 to 70 

 degrees by day, and not below 45 degrees at night, 

 will produce the best growth and the greatest 

 amount of flowers. A high temperature, with in- 

 sufficient light and ventilation, produces spindling 

 and unhealthy plants. 



Attention should be given, as far as possible, to
