Propagation.—They are propagated
by seed, layers, and slips.
By Seed. — March and April is the
season for sowing ; sow it in a bed or
border of light earth broadcast, and
rake it in. In a fortnight the plants
will come up. In June or July transplant
into nursery beds of common
earth, in rows six or eight inches distant,
to remain until autumn or spring
following, then to be taken up and
planted in the places where they are to
flower.
By Layers.— June and July is the
proper season, and the same method is
to be observed in every respect as for
the Carnation. This is the only method
of propagation to continue the
same double-flowered varieties. Being
layered, give frequent waterings in dry
weather, and they will be well rooted
in six or seven weeks, then to be separated
from the old plant, and removed
to a bed of light soil; and in October
some of them should be potted to move
to occasional shelter from frost, for
other intermediate shades of colours although the doubles are almost as
