Water freely such as are in pots, while in blossom. The flower stalks
will be apt to shoot up taller and weaker than in the garden, and will
require rods to support them. Let the rod be thrust down about _two
inches_ from the centre of the flower, and attach the flower stem to
it by one or two ligaments. Flowers in small stove rooms can be kept
in health with extreme difficulty. The heat forces their growth, or
injures the leaves. They should be washed off once a week (either on a
mild day out of doors, or in a warm room within, if the weather be
severe), as the dust settles upon the leaf, and stops up the stomata
(mouths) by which the leaf perspires and breathes. If green _aphides_
infest them, put a pan of coals beneath the stand, and throw on a
half-handful of coarse tobacco. In half an hour every insect will
tumble off. Let such as lie on the surface of the earth be removed or
crushed, as they will else revive. Plants should have _fresh air_
every day.
