the new soil they will need very little 
shade, but must have plenty of water. 
Syringe overhead in the afternoons, and 
raise the temperature 5°; by the middle 
of May pinch out the points to induce them 
to form several shoots. About midsummer 
they will, if all goes well, have filled their 
pots with roots, and should be moved into 
others 9 or 10 inches in diameter. Now 
use soil in a more lumpy state than when 
the plants were smaller, and add a similar 
quantity of rotten manure and _ sand. 
Place four or five sticks 4 ft. in height in 
the soil just inside the rims of the pots, 
round these train the shoots, tying them 
loosely, so as to give the requisite support 
and keep them from getting entangled. 
Give air early in the day through the 
spring and summer when the temperature 
of the house runs up to 80°; but close in 
the afternoons with the sun upon the glass, 
and continue to syringe overhead, and give 
plenty of water to the roots as soon as they 
have got well hold of the soil. This Bou- 
gainvillea is naturally so free in flowering 
that the plants will no doubt bloom in 
this stage of their growth; but, if the 
object is to grow them on toa large size, it 
will not be advisable to remove them 
when in flower to a conservatory, or 
similar cooler house, as that would retard 
their progress. If, on the contrary, small- 
sized decorative plants are deemed the 
most desirable, they can be placed in a 
cooler situation during the summer months, 
but when used for such purposes this Bou- 
gainvillea requires such treatment as few 
plants would bear. 
When the flowers are about half-grown, 
and before they have begun to colour much, 
the plants should be removed to the cooler 
house in which they are to remain when in 
bloom, for, if allowed to stay in strong heat 
until the flowers are fully matured, the 
check they receive in that state generally 
causes them to fall off in a few days after 
removal, whereas if they are moved while 
the flowers are growing, they will not only 
come to maturity, but last twice as long— 
often five or six weeks—as in a high tem- 
perature ; the colour is also many shades 
deeper. Yet it is not advisable to allow 
the plants to remain in too low a tempera- 
ture too late in the season. By the middle 
of September, atthe furthest, they should 
be returned to the- stove, being likely to 
suffer if the night temperature of the house 
drops below 48°. When replaced in the 
stove, no more growth should be encouraged 
during the autumn, as there would be 
difficulty in getting it ripened up before 
winter. To prevent this, water should be 
withheld until the plants flag considerably,

and then a little only should be given to 
freshen them up. Do not fully moisten 
the ball, and gradually dry them off in this 
way until only enough moisture exists in 
the soil to prevent its becoming abso- 
lutely so dry as to endanger the roots. 
Keep them in this state during the closing 
months of the year in a night temperature 
of 55°, with 5° more in the day. Where it 
is wished to extend the flowering as far as 
possible, they may be started early in 
January, the temperature raised 10° day and 
night, and all the weakest shoots not strong 
enough to produce flowering wood cut out ; 
at the same time turn them out of the pots, 
remove any loose soil not occupied by roots, 
and afterwards place the ball in a pail of 
tepid water for eight or ten hours, so that 
it may get soaked right through ; otherwise 
difficulty will be found in getting it pro- 
perly moistened, without which the growth 
will be weak. After this immersion return 
the plants to the stove for a day to allow 
the soil to drain, and then put them in the 
pots they are to remain in for the season. 
If they are not required much larger than 
the size they attained the previous year, 
they need not have pots above 3 or 4 inches 
larger than they have already occupied ; 
soil similar to that they have hitherto been 
in, but with a little more manure in it, 
should be used. They should now be 
trained on wire trellises proportionate to 
the size they are intended to be grown to, 
and syringed every afternoon. In three 
weeks they will push young shoots, which 
will grow fast, and should, as they extend, 
be kept tied in an upright position, for if 
allowed to hang down their free extension 
is stopped and they are induced to break 
back, which causes them to flower more 
sparingly by diverting the sap so as to pre- 
vent their getting so strong as desirable. 
As the roots begin to grow freely give 
plenty of water, for if ever the young 
shoots, after they have made considerable 
progress, are allowed to flag through in- 
sufficiency of moisture, they will stop 
growing and set flowers, but in much fewer 
numbers than if the growth had been 
stronger before they were formed. By the 
middle of March, as the sun gets more 
powerful, raise the temperature 5° in the 
night, allowing it to run up to 80° before 
giving air, and keep the plants well up to 
the glass. Bougainvilleas do not require 
shading from the sun, the flowers being 
more highly coloured when exposed to its 
full influence. About the beginning of 
April the plants should be in bloom, but | 
at this early season ought not to be removed 
to a cooler house. If the flower shoots are 
trained down round the trellis the plants
