perFormed not less than 1S inIches above ground in order to avoid
subsequent winter-injury to t.he smooth trunks forming above the
point of union. Ol,\~iously crown- or root-grafts are most susceptible
to this troublp. Trees worked low should be given a winter
wrapping of wooden ireneer, heavy paper, burlap, or similar material
for four to six years, or until the natural protklction of rough bark
is developed. (‘ions of last year’s growth cut while dormant and
held in storage mn)~ be used in early spring for grafting or to afford
buds for early summrr budding. For late summer budding, budsticks
may be cut from the earliest o,F the current season’s growth.
In the South, root-grat’ting is usually performed from January to
March; in the sorth from March to May, depending on weather
and soil conditions. For nursery grafting the tongue-graft is most in
use. With larger stocks, especially in top-working, the bark- or slipbark-graft
givcls maximum results. Dormant budding in late
winter or early spring is successful at the hands of skilled operators.
Later budding rntq be b>- the annular or patch methods. Special
tools haye been de\%ed for these method:: 1.1~~ which amateurs soon
become successful. No matter what method may be employed in
propagating thrh pc‘c:~n, subsequent care in unwrapping, rewrapping,
removing the wrn pping, necessary shading, staking to prevent
the new top from blowing out, pruning, guarding against insects,
and the like, art’ qually important to initial operation.
Propagation is ::omctimes accomplished by cuttings taken from
the ends of soft growing roots. See H,ic?,~ry.
Pelargonium (Geranium. Stork’s Bill). Geraniace~.
Seeds, sown in light soil with mild heat, are sometimes employed.
Commoniy increascrl by cuttings OF firm shoots, which grow readily
(Figs. 119, 121). The common geraniums, for conservatory use,
should be renewed from cuttings every Jrear. Cuttings of the zonal
or “f&h” geraniums are mostly taken from stock plants grown in
the open and lifted in autumn. The fancy or show geraniums are
grown from cuttings taken after blooming, and sometimes from
root-cuttings, but often will not come true. Geraniums can
also be grafted, the named varieties bring worked on related stocks.
