As the majority of greenhouse plants are out in the open air, or
in pits, where they have either set, or are setting, their blooms,
preparations should be made for their return, by scrubbing and washing
all the shelves of the greenhouse, and clearing out all crevices and
corners, to banish all insects that may be secreting there. When by
scrubbing, brushing, &c., you have brought everything to the ground, let
no time be lost in clearing the insects, rubbish, &c., off the ground,
and also out of the house. If painting and glazing are necessary, the
sooner they are done the better, leaving the house entirely open for
three weeks or a month, that the effluvium from white lead, which is
prejudicial to plants, may pass off before the lights are put on again.
