THE FLORIST’S JOURNAL. 
CALENDAR FOR MAY. 
Stove. This is the season of the year for growing plants of 
a permanent character, as well as those of more limited dura¬ 
tion, whose developement is become assimilated and adapted to 
our climate. The sun, supplying at once both light and heat, 
is the grand agent in forwarding the growth of plants. The 
principal artificial conditions required are these : — moisture in 
abundance, but applied in the form of invisible vapour, by 
evaporation from moistened surfaces; a low night temperature, 
affording a period of rest after the excitement of the day ; 
atmospheric air equably diffused throughout the structure, 
admitted in different proportions both by night and day, but in 
no case admitted suddenly, or in large bulk; exposure to the 
atmosphere, by not being crowded by other plants, and shade in 
some few instances, which can be afforded chiefly by climbing 
plants. Insects are sure to establish themselves if the atmo¬ 
sphere be in an arid state. Attention must be paid to pruning 
and training all plants which require it. Temperature, night, 
60° to 65°; day, 75° to 85°; or above by solar influence. 
Greenhouse. The same principles should guide the amateur 
in managing his greenhouse plants as have been recommended 
in the stove. On account of its lower degree of temperature, 
more air must be admitted, both by day and night. The moister 
the atmosphere of these structures are kept in proportion to 
their temperature, the less degree of “ fresh air” will be re¬ 
quired to be admitted. 
Flower-Garden. Almost all half-hardy and showy plants 
intended for decoration may be planted out some time this 
month, varying according to the state and prognostics of the 
weather : they should previously be perfectly inured to exposure 
in cold frames. A few annuals may be sown for succession, to 
bloom in the latter part of the summer : cuttings of free- 
growing plants may also be struck for a similar purpose. Flo¬ 
rists’ flowers in bloom require shade, in order to preserve the 
colours of their flowers, and extend their duration: those 
which are past their blooming state should be allowed to mature 
their foliage before they are removed; or if removal is indis¬ 
pensable, they should be removed as early as possible, and 
planted where their growth can he completed. Routine operations 
of all kinds should never be neglected until they become neces¬ 
sary ; their necessary performance should rather be antici¬ 
pated. T. M.
