tagc of the full growing season. In the colder sections where there
is &mger of dormant buds being injured, they are often protected
1)~ Ix~nllring kvith earth. III spring as soon as the hrli will slip,
stocks in which the buds have died are rebudded. For this work
bud-sticks of the previous season’s growth are cut, the leaves are
removed, and the sticks packed in sawdust, or sphagnum until
needed.
In spring, the tops of the dormant-budded seedlings are cut off
close 1~~1~ to the inserted buds. In some sections, the tops arch heatled
lxwk or lopped and later removed entirely, but as this entails adciitionul
~vork it sl~ould be a~oideti if growth is not too vigorous.
Sprouts rnwt berenio~ed from the stoc~ks from time to time. ;1bout
thy time the buds start to grol.v, a stake is set at ~auh one and to

they grow. Tl lis stww the ~ioul~le purpose of stying the buds from
l~real;ing away from the stocks alit1 of keeping them straight.
For propagating oranges under glass, seedlings of grapefruit or
orange imq- lw used, although the lwst stock for pot and tub plants
is t’wcirus (or C’ifws) trijllirtfn.
Orange trees of alAo& any size may be top-w&cd to other
varieties either by. t)udaling or grafting 1)~ tlw usual methods.
Sometimes the tops are cut ofi or loppc‘d, shoots aw then thrown
out and in these buds are insertetl. !311cis may !w inserted in large

The method of propagatin, cf wchitls must in each species be

It ib important that artificial means of increase shoultl l)e atlopted
only when the individual plants are in rol)ust health. With many

In cases in which thtb only iwthfl available necessitates disturl)anc!e
at the roots, consideration must 1~ paid to the constitution of the
species, for some orchids, even when perfectly healthy, strongly
resent interference. Many of the orchicls are really not propagated
under cultivation, but are grown front stock rlewly imported from
