GARDENING CALENDAR FOR SEPTEMBER. 
419 
Neriwms may be struck from cuttings, which 
they do very readily in water as well as in 
moist sandy earth. Keep the old plants cool 
and rather dry. 
Nymphmas (Water Lilies). — As the leaves 
show symptoms of decay, the plants should be 
gradually laid dry, or nearly so, and placed in 
a cooler situation for a month or two. 
Palms. — Apply water abundantly to those 
in a growing state ; but reduce it to the 
others. Keep the foliage clean. 
Thunbergias. — Those in flower should be 
plentifully supplied with moisture, and often 
syringed ; keep them neatly trained as they 
advance in growth. 
Vincas. — Plants previously at rest may be 
potted and excited into fresh growth ; they 
will soon flower. Guard against red spider. 
Begin to rest such as have been growing up 
to the present time. 
THE ORCHID HOUSE. 
Temperature. — The warm house for the 
Indian species, 85 degrees by day, 70 degrees 
at night ; the cool, or Mexican house, 75 de- 
grees by day, 60 degrees at night. 
Ventilation. — Give air cautiously, but 
rather freely among such plants as are in a 
state of rest ; close the house early, and 
maintain a proper temperature by increasing 
the artificial heat by means of fires. 
Watering, — Moisture must be applied with 
great caution, and in much smaller quantities 
than when the plants were growing. Syringe 
and damp the flowers chiefly in the morning, 
but sparingly or not at all in dull weather. 
Insects must be allowed no breathing time ; 
while the plants are in a state of rest, they 
can be closely watched for any depredators 
lurking about them. Few of their enemies 
like the drying process to which most of the 
plants will be now subjected. 
Potting. — Renew blocks where necessary 
to such plants whose roots have done growing, 
taking care to disturb or break them as little 
as possible. Most of the others will be better 
left until the period at which they recommence 
their growth. 
Shading. — This may be entirely removed 
from the plants at perfect rest, except in very 
bright sunshine, but continue a slight shade 
over any in a growing state. 
Soils. — Take every opportunity to keep up 
the necessary supply of the various articles 
requisite in this department. Where neces- 
sary for suspending, or for baskets, always use 
copper wire and nails; iron soon rusts and de- 
cays in the damp and heat of this house. 
Imported plants. — As soon as they show 
good symptoms of life, grow them away in 
order to make use of all the sun-heat left. Be 
very careful in the application of water, even 
after they are growing freely. 
Aerides, Saccolabium, and Vanda. — Con- 
tinue to supply these freely with water, and 
keep them in the hottest and dampest part of 
the house. 
Cattleya. — Grow these away," supplying 
them freely with water as they advance in 
growth, but using it very carefully in gloomy 
weather. 
Cymbidiums. — Water freely as long as 
they continue to grow, and afterwards remove 
them to a cooler situation, and reduce the 
allowance of moisture. 
Dendrobiums. — As soon as done growing, 
rest these thoroughly by withholding moisture 
to a great extent, and exposing them to 
bright sun-light, except in the hottest period 
of the day. 
Oncidiums. — As they arrive near their full 
growth the supply of water should be gra- 
dually reduced, and when the growth is com- 
pleted, they should be removed to a cool house, 
and no more moisture applied than merely to 
keep the plants from shrivelling. 
Stanhoj)eas. — Water freely while growing, 
and keep the plants in an airy place. Reduce 
the allowance of water gradually, as they 
complete their growth, and remove them to a 
1 cooler house, where they may enjoy their 
! period of repose.
