Greenhouse and Stove Plants.

atmosphere in which the plants are grown 
is kept too dry. If affected, they should be 
laid on their sides and freely syringed, 
when the insects can be easily removed, 
the smooth surface of the foliage, both on 
the upper and under sides, nct.affording 
much harbour for them; the stout sub- 
stance of the leaves also admits of the 
water being thus applied without injury. 
Where scale has made a home upon a 
plant it will be found necessary to resort 
to sponging and cleaning thoroughly with 
soapy water; a good syringing should be 
afterwards given it to cleanse it from all 
impurities. 
CYTISUS. 
The kinds here treated of are free- 
flowering evergreen greenhouse plants. 
They are in no way particular as to soil, 
growing in either peat or loam, but the 
latter is preferable, as it causes a greater 
disposition to flower. 
The different sorts of Cytisus root freely ; 
cuttings put several together in 5 or 6 inch 
pots in March, filled with sand, and kept 
moist and close in moderate warmth, will 
be sufficiently rooted in five or six weeks 
to move singly to small pots. Pinch out 
the tops at the same time, and encourage 
growth by keeping them a little close and 
moist through the spring and summer, 
shading a little in bright weather. By the 
end of June move to 4 or 5 inch pots, and 
pinch the points of the shoots when they 
have made 3 inches of growth, closing 
the pit or house in which they are grown 
early in the afternoon, and moistening 
overhead at the same time. Continue 
this treatment until the end of August, 
when inure them to more air and cease 
syringing, keeping them through the 
winter at an ordinary greenhouse tempera- 
ture. About the end of March or be- 
ginning of April give them a 3-inch shift, 
potting them in good fibrous loam, to 
which has been added one-sixth well-rotted 
dung, the latter passed through a fine sieve, 
so that all worms may be detected. Give 
a moderate sprinkling of sand and sufficient 
drainage ; pot firm, and pinch out the 
points of the strongest shoots. They 
require no support, but, like Acacias and 
some other strong-wooded things, unless 
the branches are tied down whilst young 
they have a disposition to grow erect, and 
leave the bottom leggy and bare—conse- 
quently the necessary training should be 
attended to in the first stages of cultivation. 
Through the spring syringe them overhead 
every afternoon, getting thoroughly to the 
under side of the leaves as well as to the 
upper surface, and turning the plants round 
occasionally, so that the whole may be 
reached by the water. This is necessary 
to keep down red spider, to which they 
are subject. By shutting up the house 
early while the sun is on the glass growth 
will be encouraged, and as soon as the roots- 
get well hold of the soil they must be 
liberally supplied with water, as when in 
free growth they require a good deal. 
Continue this treatment until the begin- 
ning of August, when the plants should be 
turned out-of-doors and stood on a bed of 
ashes, in a situation where they will be 
protected from the mid-day sun ; they will 
now require well attending to with water 
at the roots, which will have filled the: 
pots by this time. Continue also to 
syringe overhead every evening during dry 
weather. By the middle of September it 
will be advisable to take them indoors ; 
they will do in any house or pit where 
there is a fair amount of light, and from 
which frost can be excluded. By placing. 
a portion of them in a temperature of 50°,, 
about the close of the year, they can be had 
in flower early, and others will succeed 
them started later, to be followed by those 
that bloom with the advent of solar heat. 
After they have flowered, go over the 
whole with the knife and cut back the 
leading shoots so as to keep the plants in 
shape ; and when they have broken and 
the roots begin to move again, pot them, 
giving a 3-inch shift, using soil similar to 
the preceding year, and treating in every 
way as before advised. They may be 
grown on to a large size if required, but 
will bear cutting back, the balls consider- 
ably reducing, and repotting in new soil, 
but after this operation they should be 
kept close and a little warmer until growth 
has fairly commenced. 
CO. filipes is a white-flowered species, of 
very slender, graceful, drooping habit, and is 
much used grafted on straight, clean stems 
of the Laburnum, 2 or 3 feet high, so as to: 
form pendulous standards. So managed it 
is one of the most elegant plants grown, 
especially for conservatory decoration, 
where, standing above lower-growing 
things, it is very effective. The stocks 
will succeed either from seeds or cuttings.. 
After grafting the plants will thrive satis- 
factorily with general management such as 
advised. 
C. racemosus superbus. This is a garden 
hybrid, a considerable improvement on the 
old C. racemosus, and one of the most 
useful decorative plants grown, producing 
most freely its racemes of sweet-scented, 
bright yellow flowers through a good por- 
tion of the spring.
