FLOWER GARDEN.— IN-DOOR DEPART- 
MENT. 
Conservatory. — Plants in bloom are now so numerous 
that considerable discrimination wiU be necessary in 
furnishing this house. Avoid crowding the plants ; by 
every means, and by frequent re-arrangement of the 
plants, endeavour to keep up the interest as much as 
possible. Remove decaying plants directly they become 
shabby, and attend scrupulously to cleanliness in every 
part. Guai'd against insects by timely fmnigation, or 
washing, and also against mildew upon plants subject 
to it. Train creepers, and regulate the growth of those 
plants gi-owing in the borders. Water copiously, both 
at the roots and with the syringe ; and give the plants 
occasionally a good soaking of liquid manure. Venti- 
late fi'eely, both by night and day ; but avoid cold 
draughts through the night. Some of the Camellias 
will now have completed their growth, and, therefore, 
may be removed to a shaded place in the open ah', as 
may also Acacias, and other large plants growing in 
pots or tubs. 
Orangery. — Pursue the same general treatment as 
last month, maintaining a brisk moist temperature, 
and water copiously at the roots with liquid mamu-e. 
Where young plants are gi-owiug fi-eely, stop the stoutest 
of the young shoots to make them branch. Early 
fruit will requu'c thinning, and where weakly ti'ees 
have set, or are setting a heavy crop, it will be advisable 
to give a slight thinning at once. Give a little night 
air, but not too much for the present. A. 
Orchid House. — Continue to pot and shift, according 
to former directions, and you have nothing to fear but 
that you will be able to compete with anybody, as 
regards health and vigour, if not in size ; for that, wait 
a little longer, and your object is achieved. Take 
great care not to satm-ate the plants at the root in dull 
weather, but keep a nice humid atmosphere, with a 
temperature of about 70 to 80 degrees. Be very cautious 
that the plants are not bmned by strong sunshine after 
a few dull days, as is frequently the case ; rather shade 
an horn" too early than a minute too late, and, at the 
same time, give them just what Mr. Spencer objects to 
give to his Vines, namely, a vapom- bath. The moist- 
ure of the atmosphere is a matter too little attended to 
by many who profess to grow this singularly interesting 
tribe of plants ; but a moist atmosphere in the growing 
season is the mainspring of success in the cultivation 
of Orchids, and inattention to it must result in com- 
parative failm-e. For the same reason, always avoid' 
lofty houses ; for in such it is impossible to grow these 
plants successfully. 
Stove. — In this house all should be clean, and the 
plants vigorous. Let there be no jumbling together ; . 
rather remove to pits or fr'ames, or throw away alto- 
gether, anything ijiat tends to injiu'e a fine grown 
specimen. These must all stand quite fi-ee ; and never 
forget that twenty good plants, well selected and grown, 
are far better than double that number of Ul managed 
things. Let nothing be stinted for want of timely 
shifting. Guai-d against Thiip and Red Spider among 
young stock in the dung frames, and watch daily for 
theu' appearance upon Echites, Dipladenias, Gardenias, 
and Rondeletias, and carefully wash them off with a 
very soft sponge. This must be persevered in to the 
death. Give plenty of weak liquid maniu-e to all 
strong-growing plants, as Clerodendrons, Hedychiums, 
Alpinias, Aristoloehias, Stephanotis, AUamandas, and 
aU similar fast-growing plants. Use the syringe freely, 
but with cautious force, in this house, as a preventive 
against insects. Should the Green-fly make its appear- 
ance upon any particular plant, take it out, and wash 
it clean off, in order to avoid, as far as is consistent, 
the use of frimigation, which is a great annoyance both 
to the plants and om-selves. J. G. 
GREENHOUSE HARD- WOODED PLANTS. 
Now that all danger fi-om frost is over, most of the 
lai'ge specimens wUl do best placed out of doors in 
rather a sheltered, shaded situation. A screen formed 
of some fo-ee growing things, such as limes or privets, 
answers the pm-pose weU. It is quite as important a 
matter to have good summer quarters for plants as a 
good house for them in winter. After standing them
