Some of the earliest blooming kinds of these will now begin to flower,
and the sun will greatly deteriorate their rich colours where they are
near the glass with a south aspect. The glass should be white-washed,
which will cast a thin shade over them, and prolong the duration of the
bloom, but if they are above five feet from the glass, white-washing is
not requisite. The strong kinds will be growing very luxuriantly, and
require liberal supplies of water. When syringing, do not sprinkle the
flowers, as it would make the colours intermingle with each other, and
cause them to decay prematurely. If they have been properly attended to
in that respect, it may be dispensed with after they have generally come
in flower, which will not be until about the first of May.
