Those _Alstr[oe]merias_ that are growing freely, and in small pots, should
be put into pots of a larger size. This genus of plants will not flower
except they are encouraged with frequent shifting: they are all
beautiful.
=Green-House.=
_MARCH_.
The plants in this compartment will begin to assume a different aspect,
and air must be admitted every day if practicable, giving large portions
in sunshine by the sashes regularly over all the house, opening those of
the front a little, and likewise the doors in fine mild days. To perform
this judiciously, give a little about eight or nine o'clock, more at
ten, and the whole from eleven till twelve o'clock, shutting again by
degrees.
Fire heat will now be dispensed with, but in frosty nights have the
shutters on about sundown. The sun is now powerful, and the house can be
early shut up in the afternoon, and will gain as much natural heat as
will keep up the required temperature, viz. 36° to 40°. Perhaps there
may be uncommonly cold weather; at such times be attentive to ward off
danger by applying artificial heat.
