Dipladenia— continued. 
hybrids are unrivalled for brillianey of colour, especially if 
the plants are allowed free root room, in a prepared border. 
They are also well adapted for exhibition purposes, in 
which ease it will be necessary to cultivate in large pots, 
to admit of removal When in flower, and well grown, 
Dipladenias, in either of these positions, must be classed 
amongst the most beautiful of stove plants. 
Propagation is effected by cuttings of the young shoots 
that are produced when the plants commence new growth, 
in spring. These, or single eyes, should be inserted in 
a compost of equal parts sand and peat, covered with 
a bell glass, and placed in a brisk bottom heat. Roots 
will soon be emitted, and the young plants may then be 
transferred to separate pots, grown on, and shifted into 
larger sizes as required. 
After - Cultivation. This will consist chiefly in sup- 
plying plenty of heat and moisture in the early part of 
the season, and in thoroughly ripening the main growths 
in autumn for the succeeding year. А suitable compost 
is fibry peat, broken up roughly for use, with sufficient 
silver sand added to insure the free passage of water. 
Drainage must also be efficient, as few flowering subjects 
show the effects of a waterlogged soil quicker than do 
these. Young plants should be grown on without stop- 
ping, and be supported by a stake until of sufficient size 
to be placed on a trellis. This is best made of small 
galvanised wire, and a conical or globular form is most 
suitable. If intended for planting out, to train on the 
roof of a stove—a position best suited for showing the 
flowers of Dipladenias—the trellis will be unnecessary, as 
the plants may be trained upright until established, and 
then placed out permanently. If a little bottom heat 
can be obtained, it will be of material assistance. The 
flowers are produced in profusion all the latter part of 
the summer, on the wood of the current year. Nearly 
all this should be removed when the flowering season 
is over, unless required for main shoots to cover the 
trellis. Dipladenias should be kept warm and in a 
moderately dry condition when at rest in winter, gradu- 
ally introducing more moisture to start them in spring. 
Plenty of heat and frequent syringings, in early summer, 
wil encourage the production of good flowering wood. . 
The plants are subject to the same insect pests as many 
others grown in the high temperature of a stove. 
When insects are detected, sponging the leaves and 
stems will prevent their i increase, and is the best method 
of destruction.
