THE N ITRSERY-LIST 341
Jasminum (.Jnsmine. ,Jt-assaminc). olfw~r cr.
Propagated rcatlily l)y cuttings of nea.rly mature wood under
glass in summer ; c also by ripe-wood cuttings t.aken. in autumn, by
layers, a.iid sometimes by seeds sown as soon as ripe.
Jatropha. Elr~)ho~bicrc~c~r.
Readil?. txised from sr~ls. Propagated also by cuttings from
firm >*oung wood struck in sand over bottom heat, ; the cuttings
should be dried somewhat. before setting, as the plants have milky
juice.
Jubea ((“oquit o Palm of Chile) . Z+-dmacm.
Propagation is b>- seeds, started in a warm house and kept moist.
SW Pulws, page 377.
Juglans (iYalnut. and But tcrnut). Juglan.dacrm.
All the .ipecies art readily propagatrd b>- mean3 of stratified
nuts. Ilo not allow the nuts to become dry. Artificial cracking
should not be pra.cticed. In stiff soils the seedlings are likely to
produce a long tap-root which renders transplanting difficult after
the first. ;-car or two. The t.ap-root ma.>? XW cut by a long knife
while the tree is growing, or t.he j-oung seedling may be transplanted.
Particular varieties art‘ perpetuated by graft.ing or budding with
any of the common methods ; but the skill of the grafter is more
important than the method. In the North, they are sometimes
worked indoors in pots. ( ‘ommon shield-budding works well, if
the sap is flowing freely in the st.oek. Flute-budding is often
employed. Tl le improved native sorts are root-grafted in winter.
Old trees can be top-grafted like apple t,rees (see page 151). If
nursery stocks are graft,ed, it is usually best to insert the cions
below ground, as for grapes. In all walnut grafting, it is generally
preferred that only one scarf or cut of the cion should traverse the
pith. It is important that the cions be kept perfectly dormant.
The “ English ” wa.lnut (J. re@) is mostly grown direct from
seed in this country, and the different varieties usually come true.
In California, the native walnut (,1. Hindsii and J. cal~fornica) is
often used as a stock for this species, and flute-budding’on branches
a half-inch or more in diameter is ot‘ten ,practiced. Twig- or prongbudding
(Fig. 146) is sometimes employed. See bt’alwt.
