become hard and dry through long exposure to the air, or
they will germinate unevenly. Apple seeds procured at the
seed stores are often worthless because of this neglect. Very
dry seeds can sometimes be grown, however, by subjecting
them to repeated soakings and then sprouting in a gentle hot-

bed or mild forcing-house. Change the water on the seeds
every day, and at the end of a week or ten days mix with
sand and place in a thin layer in the hot-bed. Stir frequently
to prevent molding. When the seeds begin to sprout, sow
them in the open ground. This operation, which is some-
times called pipping^ may be performed in a small way by
the kitchen stove. Seeds are sometimes "pipped " between
moist blankets. (See also page 17.)

When sowing is done in the fall, the seeds may be sown in
the pomace. This entails extra labor in sowing, but it saves
the labor of washing. This practice gives good results if
the pomace is finely broken, and it is now common among
nurserymen.

In loose and well-drained soils, sowing is undoubtedly best
performed in the. fall, just as early as the seeds are ready.
But upon land which holds much water, and which heaves
with frost or contains much clay, spring sowing is preferable.
In spring, the seeds should be sown just as soon as the ground
can be worked.

If the stocks are to be cultivated with a horse, the rows
should be three or three and a half feet apart. Some grow-
ers sow in narrow drills and some in broad ones. The broad
drills are usually six to ten inches wide. The earth is
removed to the depth of two or three inches, if it is loose and
in good condition, the seed is scattered thinly on the surface
and the earth hoed back over them. If the ground is likely
to bake, the seeds should not be sown so deep ; and it is
always well, in such cases, to apply some very light and
clean mulch. The plants should be well cultivated during
the season, and they should attain a height of six to twelve
inches or more the first year. If the plants come thickly,
they must be thinned out.

In the fall of the first year the seedlings should be large
enough to be dug and sold to general nurserymen. Some-
times the poorest plants are allowed to stand another year,
but they are usually so scattering that they do not pay for the
use of the land, and they should be transplanted the same
as the larger stock, or the weakest ones may be thrown away.
The stocks are dug with a plow or tree-digger and heeled-in
closely, so that the leaves." sweat " and fall off. The plants
are then stored in sand, moss or sawdust in a cellar. Before
they are shipped the tops are cut off near the crown, usually
with a hatchet on a block. The stocks are then graded into
budding and grafting sizes. The general nurserymen buy
these stocks in fall or early winter. Those which are root-
grafted are worked during late winter, but those intended for

budding, or which must be grown another season before
they attain sufficient size for working, are "dressed" (See
Chapter V) and heeled-in ; in the spring they are set in
nursery rows, from a foot to eighteen inches apart in the
row. The nurseryman reckons the age of his tree from the
time the seedling is transplanted, rather than from the time
the seed was sown.

Seedling raising is usually conducted by men who make it
a business and who supply the general nurserymen of the
country. It is largely practiced at the west, where the deep
and strong soils produce a rapid growth. The yearling trees
are graded by the western growers into about four lots :
"Extras," or those at least one-fourth inch in diameter at the
crown and having twelve inches of both top and root ; these
are used mostly as budding stocks the next season. "Com-
mons," those between three-sixteenths and one-fourth inch
at the crown and having eight inches of root ; these are used
for immediate root-grafting. "Second-class," those from
two to three-sixteenths inch at the crown, and "third-class,"
or all those under two-sixteenths. The last two classes must
be grown in the field for one or two seasons before they can
be worked.

Dwarf stocks are mostly obtained from mound-layering.
The common stock for dwarfing is the Paradise apple, a
dwarf variety of the common apple species (Pyrus Malus).
This variety rarely attains a height of more than four feet.
A larger or freer stock is the Doucin, also a variety of Pyrus
Malus, which will produce an engrafted tree intermediate in
size between that given by the Paradise and free or common
stocks. This is little used in this country. To obtain stools
for mound-layering, the tree, when well established, is cut
off within four or six inches of the ground in spring, and dur-
ing the summer several shoots or sprouts will arise. The next
year the stool is covered by a mound, and by autumn the lay-
ers are ready to take off. Sometimes, when stocks are rare,
mound-layering is performed during the first summer, before
the young shoots have hardened, but good stocks are not ob-
tained by this method. Common green layering is sometimes
practiced the first year, but it is not in favor. The dwarf
stocks, in common with all apple stocks, may be propagated
by root-cuttings and by hard-wood cuttings.

Apple stocks are either grafted or budded. Root-grafting
is the most common, especially at the west where long scions
are used in order to secure own-rooted trees. (See Chap-
ter V. ) Budding is gaining in favor eastward and southward ;
it is performed during August and early September in the

northern states, or it may be begun on strong stocks in July
by using buds which have been kept on ice. Stocks should
- be strong enough to be budded the same year they are trans-
planted, but the operation is sometimes deferred until the
second summer. Stocks which cannot be worked until the
second year are unprofitable, especially on valuable land.
For root-grafting, strong one-year-old roots are best, but
two-year-olds are often used.

In common practice, the root is cut into two or three
pieces of two to three inches each, but stronger trees are
obtained, at least the first year or two, by using the whole
root and grafting upon the crown. The lowest piece is
usually small and weak and is generally discarded.

The apple is easily top-grafted and top-budded. (See
Chapter V.)
Apple Berry. See Billardiera.
Apricot i^Prunus Armeniaca), Rosacem.

The apricot thrives upon a variety of stocks. Apricot
stocks are used in apricot-growing regions, especially for
deep and rich well-drained soils. The pits grow readily if
given the same treatment as that detailed for the peach
(which see). The stocks are also handled in the same man-
ner as peach stocks. Apricots upon apricot roots are not
largely grown outsideof California, in this country. Apricot
stocks can be grown from root cuttings the same as cherries
and other stone fruits.

The apricot does well upon the peach, especially on light
soils. In the warmer parts of the country peach is much used.

Plum stocks are commonly used at the north, especially if
the trees are to be planted in moist or heavy soils. The
common plum is generally used, but some of the native
plum stocks are now coming into favor, especially in trying
climates. The Russian apricots, which are a hardy race of
Prunus Armeniaca, are grown in colder climates than the
common varieties, and they therefore demand hardy stocks.
Any of the native plums make good stocks, but the Marianna
is now coming into especial prominence. The myrobolan
plum can be used for all apricots, but it is not popular, par-
ticularly in severe climates.

The almond, both hard and soft-shelled, is sometimes used
for the apricot, but the union is likely to be imperfect and it
is not recommended. Almond-rooted trees are best adapted
to light soils.

Varieties of apricots are usually budded, in the same way
as the peach, although they may be side-grafted at the crown
in the nursery row.

Propagation is difficult. Suckers may be utilized when
procurable. The young and slender lateral growths are used
for cuttings.
Arum. Aroidece.

Propagated by seeds, but usually by division of the roots,
the best time being just as they begin their new growth,
securing as many roots as possible to each division. Any
rootless pieces should be placed in heat shortly after re-
moval ; this hastens the formation of roots and excites top
growth. Arisasmas are treated in the same way.
Arundinaria. Gramineie.

Increased by division of the root.
Arundo (Reed). Graminem.

Propagated by seeds or divisions, spring being the best
time for either method. In early autumn, the canes can be
cut into lengths of j8 to 24 inches and partly buried in sand
in a gentle bottom heat, laying them horizontally.
Asaruin. Arisiolochiacece.

Propagated easily by divisions in spring.
Ascaricida. See Vernonia.
Ascium. See Norantea.
Asclepias (Milk- weed, Swallow-wort). Asclefiadece.

Increased by seeds sown in pots in spring, pricked out
singly when large enough, and treated like cuttings. By
cuttings, which should be secured in spring, struck in gentle
heat, under a bell-glass, and as soon as they are well-rooted
potted into small pots. Seeds of A. tuberosa must be sown
or stratified at once.
Ascyrum. Hypericins .

Increased by seeds and by careful divisions of the roots in
spring.

Propagated by young cuttings of half-ripened wood, placed
in sand, in spring, under bell-glasses, which must be wiped
dry occasionally.



124 THE NURSERY-BOOK.

Asparagus. Liliacece.

The common kitchen garden asparagus is best propagated
by means of seeds. These are sown in spring as soon as the
ground can be worked, usually in rows a foot or two apart.
Thin the young plants to two or three inches apart in the
row and give good culture, and the plants can be set in the
field the following spring, and they will give a fair crop after
growing there two seasons. Small growers nearly always
buy plants of nurserymen. Old asparagus crowns can be
divided, but seeds give better plants.

The ornamental species of asparagus are propagated by
seeds when they are obtainable ; otherwise, by division.
Asperula. Rubiacece.

Increased by seeds and by divisions of the roots during
spring and early summer.

they are produced.

Astragalus (Milk Vetch). Leguminosce.

Seeds should be sown in pots of sandy soil placed in a
cold frame, as soon as ripe, or early in the spring, as they may
lie a long time before germinating. The herbaceous peren-
nials also increase by divisions, and the shrubby kinds slowly
by means of cuttings placed in a cold frame.

In early autumn carefully transplant to a cool shady bor-
der. Also by divisions. Where a stock of old plants exists,
layer their long slender branches any time after flower-
ing, and cover with a mixture of sand and leaf soil ; they
will then root freely and establish themselves in time for
spring blooming. Cuttings should be " drawn " or grown
in a frame until they are soft, before they are removed.

Aucuba. Cornacex.

Readily increased by seeds, sown as soon as ripe ; or by
cuttings, inserted in spring or autumn in sandy- soil, with or
without a covering.

Increased by ripened cuttings, taken off at a joint, and
inserted in pots of sandy soil. These will root well under a
hand-glass, in a cool house.

Auricula {Primula Auricula). Primulacece.

Propagated by seeds, sown as soon as ripe or in spring, in
well-drained pots, filled with sandy soil, well watered pre-
vious to sowing. Cover lightly with coarse sand, place a
pane of glass over the pot, and place the latter in a hand-
glass. By offsets, which should be removed when top-
dressed, as they are more likely to root. Arrange about
four offsets around the sides of well-drained three-inch pots,
filled with sandy soil, place under a bell-glass or in a close
hand-light, water very sparingly so as to prevent them
damping off After becoming established, admit air, and pot
off singly.

root in sand, under a hand-glass, with bottom heat.

Axillaria. . See Polygonatum.

Azalea. Ericacea.

Increased by seeds, sown as soon as ripe, or early the fol-
lowing spring, in a large shallow frame containing from two
to three inches of peat, over which more peat must be spread
by means of a fine sieve ; do not cover, but water thoroughly.
When the seedlings begin to appear they should have air,
shade, and a daily sprinkling of water ; transplant in autumn
in boxes of peat and coarse sand,, water, shade and keep close
until growth commences. Grafting is largely practiced to
increase the stock of named varieties or choice seedlings, the
stock most employed being ^. pontica for hardy sorts, and
some strong growing variety of A. Indica, like " PhcBnicia,"
for tender ones. Layering in spring, enclosing the part bur-
ied with moss, is also practiced ; but the layer must be left
two years before separating. Cuttings of the last year's
wood two or three inches long, taken with a heel, root read-
ily in sand ; about the end of summer is the best time. When
placed outside they should be covered with a hand-light for
about two months, and at the end of that time air should be
given freely.
