Push Allamandas, Clerodendrons, Stephanotises, &c., forward as briskly
as possible; but be in no hurry to train them, as freedom in growth is
advantageous to a certain extent. Use all means to check the increase of
insects.
Orchids.--The general collection to be favoured with a good steaming
every clear morning for about half an hour: this to be done by
sprinkling the flues or pipes when warm. Plants in a growing state to
be slightly shaded, to prevent flagging from too copious a perspiration
during a sudden mid-day bright sunshine. Orchids are generally increased
by passing a sharp knife between the pseudo-bulbs (taking care to leave
at least two or three undisturbed next the growing shoots) so as to
sever one or more of the dormant bulbs from the parent plant, which
should remain until it shows signs of growth, when it may be taken off
and potted.
