ing atmosphere, by spinging the plants daily mth 
tepid water. Spriidde the paths, walls, and pipes, twic^ 
or thrice a-day, and sprinkle occasionally among th6 
pots with mamire water, so as to impregnate the atmo- 
sphere with a Uttle ammonia. If the mealy-hug and 
other insects have not either been exteiminated or ma- 
terially subdued, lose not a moment in attacking them, 
or, depend upon it, yon wiU not have any difficulty in 
finding a job after the plants get into free growth. Ee- 
collect prevention is better than cure. 
Some of the plants started last month -nTll be gTow- 
ing vigorously ; sprinkle them daily, and, as far as con- 
venient, assist them with a little bottom heat. Dipla- 
denia splendens is a jjlant worthy of its specific desig- 
nation, and two or three nice plants, potted now into a 
large pot in free, open soil, will make a splendid speci- 
men for summer and autimm blooming. It requires 
plenty of heat. Some of the fi'ee-growing Cleroden- 
drons will probably require shifting ; Gloxinias and Achi- 
menes, &c., started in the old soil, must be potted im- 
mediately into fi'esh compost. This is a good time to 
start some stocky plants of the various species of Ixora, 
giving them, if well rooted, a liberal shift, using strong 
turfy peat and plenty of sand and potsherds. The fol- 
lowing are the best kinds : — I. grandiflora, javanica, 
crocata, Grifflthsii, and alba, a neat little plant, deserv- 
ing of every attention. Start a pot or two of Gloriosa 
superba, by shaking the tubers clean out of the old 
soil, and potting them into a rich light compost of peat, 
leaf mould, and loam, with sand and potsherds to make 
it quite porous. This plant requires considerable bot- 
tom heat, and, when growing freely, plenty of manure 
water. Some of the winter-blooming Justicias, &c., will 
now be getting shabby, and, consequently, may be re- 
moved to make room for more important things. Take 
what cuttings are reqiured, and place the old plants in 
any by-comer to rest for a few weeks. This moU make 
room, and, consequently, a fresh batch of Achimenes, 
&c., may be started. 
Soutine. — Keep plenty of soils, pots, crocks, &c., 
always in readiness for use, and take care that great 
cleanliness is obseiwed in every quarter. Guard spe- 
cially against insects of all kinds. J. G. 
GREENHOUSE HAED- WOODED PLANTS. 
Greenhouse plants generally are now fairly on the 
move. Great care must be taken to attend regularly to 
their wants in every respect. If there be one season 
for a general potting, it is certainly the month of March. 
To make more room in the house for the better sorts of 
plants, tm'n some of the second-rate kinds into a cold 
pit, or some place where they can be readily protected 
from frost. Make a thorough re-an-angemcnt in the 
house, moving the plants from one end to the other, 
washing the shelves, stages, pots, &o. 
Newly potted plants must be watered with care. 
They should be allowed to stand for a week or ten days 
after potting, before they are watered at all, when it 
should be done effectually. The pots of plants standing 
next to the front lights, should be shaded in strong sun- 
shine, to prevent the sides of the pots becoming hot, 
and the roots being dried up. In fine, bright weather, 
the syringe may be used with advantage two or thi-ee 
times a- week ; but you may easily do too much with it, 
for it will not do unless the weather is fine. Good spe- 
cimens of hard-wooded plants are much wanted to 
bloom in July and August. EoeUia cUiata, Burtonia 
violacea, Eelhania speciosa, and a few others, should be 
shifted and encouraged ; they are excellent plants if 
well grown to flower during summer ; the different 
sorts of Statice are also good plants for the same pur- 
pose. The former should be potted in peat and sand, 
but the Statices do best in equal pai-ts of peat, loam, and 
leaf mould. Epacrises, of the Impressa varieties, should 
be well cut back after flowering, and placed in a rather 
close but light situation, until they begin to break, when 
they must have plenty of air, and a good shift, prepara- 
tory to turning them out of doors. In potting them, use 
strong tm-fy peat mixed with plenty of sand. Erioste- 
mons, of all sorts, are first-rate plants, and should be in 
every collection ; they grow best in strong peat and 
sand, and if placed along with the Boronias in the 
wai'mest part of the house, will soon make rapid pro- 
gress. Pimeleas and other free-flowering plants, if 
wanted to make large specimens, shordd have the bloom 
buds picked off as they appear, to induce them to make 
more gi'owth. 
Camellias. — Now is the time to inarch any worth- 
less varieties with good sorts. Hants that are much 
" pot bound" may be shifted before they commence 
grooving, but generally they do best potted after the 
groMfth is about half ripened. Use the syringe freely 
towards the end of the month, and be sure to avoid cold 
cm-rents of au\ 
Azaleas. — Those plants potted and placed in heat last 
month, -nTll require stopping and ti'aining. Keep a 
shai-p look-out for thiips, and should these pests appeal', 
the plants must be sti-ongly fumigated with tobacco, 
and well washed with the syringe atterwai-ds. J. F. 
Scatliery . — Presuming that soU, pots, &c., have been 
prepared as dii-ected last month, no time must be lost 
in getting the specimen plants shifted with as little de- 
lay as possible. Those who have availed themselves of 
the West Kent pot, and have large plants to re-pot, 
will be able to appreciate its excellence ; and those who 
have not used it, may regret that they were not wise in 
time. In shifting lai'ge plants, take care that the ball 
is in an uniform state of moisture, that is, neither wet 
nor dry ; and guard also against the compost being dry 
at the time of using it. If the plants, more especially 
the free growing, are vigorous and well rooted, do not 
spare pot-room ; but guard carefully against over-shift- 
ing the delicate kinds. Take care to di-ain the pots 
thoroughly with potsherds and charcoal broken small ; 
but recollect Heaths are not air plants, and that it is 
possible to over-drain them. We have a strong objec- 
tion to using Moss over the drainage, as, if it gets dry, 
it is a difficult matter to moisten it ; and hence esta- 
blished plants frequently receive very considerable in- 
jury. In potting, take care to press the soil fii-m ; but 
it is not necessary to follow the example of our fore- 
fathers, and consolidate the soil as much as if we were 
fixing a gate-post. After shifting, the plants must be 
watered ; and the house should be kept rather close for 
a week or two, until the roots take with the new soU. 
Ventilate cautiously, avoiding di'aughts, especially of 
dry an-, until the plants are re-established ; damp the 
house daily, and a syi'inge of clean water di'a-\vn over 
the plants on a fine clear morning will not do them any 
injury. Those who are just commencing the cultivation 
of Heaths AviU find the following a nice lot of free- 
growing kinds to tiy theii" hands upon. When they 
have succeeded in understanding these, a second lot 
win be recommended to their notice : —
