THE PROPER CONDITIONS II 
ease and greater success in the management of 
plants, and by the wider scope permitted. 
TEMPERATURE 
Next in importance to light, is the matter of 
temperature. The ordinary house plants, to be 
kept in health, require a temperature of sixty-five 
to seventy-five degrees during the day and fifty to 
fifty-five degrees at night. Frequently it will not 
be possible to keep the room from going lower at 
night, but it should be kept as near that as possible; 
forty-five degrees occasionally will not do injury, 
and even several degrees lower will not prove fatal, 
but if frequently reached the plants will be checked 
and seem to stand still. Plants in the dormant, 
or semi-dormant condition are not so easily injured 
by low temperature as those in full growth; also 
plants which are quite dry will stand much more 
cold than those in moist soil. 
The proper condition of temperature is the most 
difficult thing to regulate and maintain in growing 
plants in the house. There is, however, at least 
one room in almost every house where the night 
temperature does not often go below forty-five or 
fifty degrees, and if necessary all plants may be 
collected into one room during very cold weather. 
Another precaution which will often save them is 
to move them away from the windows; put sheets 
of newspaper inside the panes, not, however, touch-
