The reader must not suppose that all rose cuttings are made
after the fashion of Fig. 123, although that is a popular st;.rl:~b.
Tea roses, and other forced kinds, are largely propagated ~AVL
softer wood cut to a single eye, with most or all of the leaf left
on (Fig. 1%).
These firmwood cuttings, about two inches long, are often
made in the winter from forced plants of many kinds. Cuttings
taken in February, in the North,
will be ready to transfer to borders
or nursery beds when spring opens.
Stout well-rooted stock-plants are
used from which to obtain the cuttings,
and t,hey are cut back when
taken to the house in autumn, in
order to induce a good growth.
Many hardy shrubs can be easily
propagated in this way when the
work is difficult or unhandy in the

Stock plants of the soft species, as
coleus, lantanas and geraniums, are obtained in like manner.
In the potting of rooted plants, care is taken to &rn the
earth ; and good workmanship requires that the plant be centered
in the pot. Fig. 126 shows the operation.
