soft tip-cuttings of roots. It is probable, however, that all
plants can be multiplied by cuttings if properly treated.
It often happens that one or two species of a closely defined
genus will propagate readily from cuttings while the other
species will IH )t, SO that the propagator comes to learn by experience
that di!-krtM trtaatment is profitable for very closely
related plants. For t5ample, most of the viburnums are propagated
from la,~rs in commercial est.a~)lishnlents, but I,‘,
t(~lrlt)ntosrr~~~ (often l~nown as l-. pliratlm) is grown extensively
from cuttings.
-1 I. TIIE: DIJ’ERS KINDS OF CUTTINGS
I‘uttings arc made from all parts of the plant. In its lowest
terms, cuttagc is a division of the plant itself into two or more
IIWrlJr e(]Ilal IXlI’tS, as in the division of crowns of rhubarb,
dicentra iillti rlwst 0thtT l)lailts tlliLt tend to form broad masses
or stools. I’his spe&~ of crlttagc is at times indistinguishable
from separation, ~1s ill the dividing of lily Mbs (page ST), and
at other times it, is WWlltii111~ tile salne as la?-erage, as in the
dividing of stools that Slave arise11 from suckers and layers.
This breaking or (buttin g up of the plants into two or more
large parts that, are alread> root331 is technically known as -
division, md is tliscussed 1n Chapter III. It. is only necessary,
in dkidiiig plants, to set’ that air or more btids or shoots remain
on the portions, r nid these portions are then treated iu the same
way as intlependcnt niaturcl plallts, or sometimes, when the
clivlsioiis are sikdl anti w~uk, t,heJl inzyv be handled for a time
in a frame or for&g-house as ordinary cuttings.
Cuttings proper niq- be cli\irletl intri fr!~ gellera! t!a.s3CS,
with respect to the part, of the plant from which they are made :
1, of tubers ; 2, of roots and rootst~ocl;s ; 3, of stems ; 4, of
leaves. All these forms of cuttings reproduce the given variety
with the Same degree of certainty as do grafts or buds.
