Cultivation: For obtaining the best results, an open situation should

be chosen, free from the shade of trees. The ground should be light

and sandy, and, if possible, that which has been previously manured

for some other crop, French beans, for instance. Trench the soil to a

depth of 2ft. in the autumn, and ridge it up for the winter. As soon

as dry enough to allow of working in spring, dig over the whole bed

with a steel digging fork, and break the soil tolerably fine. Sow any

time from the last week in April to the end of May. Prepare the drills

about a foot or 15in. apart, and from 1in. to 2in. deep. The seeds grow

quicker if steeped in water previous to sowing, afterwards allowing

them to get dry enough to separate from each other. Sow thinly, and

fill in the drills with a rake. As soon as the plants are up, hoe

between the rows, and keep free from weeds. In a fortnight or three

weeks after this hoeing, if the weather has been favourable, the plants

will be large enough for thinning. Thin out to about 9in. apart,

and carefully fill up, in dull weather, any blanks that may occur.

Transplanting is, however, not generally a very satisfactory method.

Carefully lift the roots in autumn, before frost comes, and wring off

the leaves about an inch from the crowns. Place the roots in a cool

shed or house, and allow the soil on them to get quite dry, when they

may be stored for winter use in dry sand, or soil, in a shed free from

frost. It is preferable to keep the crowns free from soil, to prevent

decay from the ends of the leaves left on them. If this be carefully

done, the roots will keep till the next season's early crop is ready.

In all processes connected with the growing, storing, or cooking of

this vegetable, the greatest care must be taken to avoid bruising or

otherwise injuring the roots, as deficiency of colour would be the

result, especially in the case of the red-fleshed kinds, in some cases

rendering them valueless for table use. Seed Saving: When lifting the

crop in autumn, select as many of the best formed and coloured roots as

required, and store them separately from the rest. In April, plant them

in a spot by themselves, where there is no danger of impregnation from

other varieties, and in due time good seed will ripen. If good foliaged

varieties are required, the best should be selected when growing in the

summer, and either be marked by some means, or have the inferior ones

removed from them.

_Sorts._ These are somewhat numerous--almost every seedsman having a

so-called "improved strain." Nutting's Dwarf Red, Chelsea, Pine Apple,

Dell's Crimson and Red Castelnaudary, are the best of the crimson or

red-fleshed kinds. The Egyptian Turnip-rooted is a distinct variety,

with flesh of a good colour, and fine flavour; excellent for summer

salads. Betterave de Bretagne is a Continental variety; the roots grow

to a good size, with a distinct outer skin of a dark colour; flesh

rich purple. The best of the yellow-fleshed kinds are Small Yellow and

Long Yellow (see Fig. 222); but these are not grown nearly so much as

the deep-coloured section; in fact, they are almost useless for garden

purposes.

[Illustration: FIG. 223. WHITE LEAF BEETROOT.]

_Beetroot for Bedding Purposes_: In this case, where the foliage is

the main object, the seed may be sown in a reserve bed, and the plants

transferred to their positions in the flower garden. If, however, a

line is required in a ribbon or other border, the best plan is to sow

there, and thin out the plants to equal distances. Dell's Crimson is

one of the best varieties for this purpose, being very compact and of

a good dark colour.

Varieties of the Leaf Beet (_Beta Cicla_), and Sea or Perennial

Beet (_Beta maritima_), are sometimes, but very seldom, cultivated

for the use of the leafstalks and leaves, the roots being hard and

unfit for cooking purposes. They are at the best but substitutes for

other vegetables--namely, the midrib for Sea-kale and the leaves

for Spinach. If desired, seeds may be sown in the way described for

Beetroot, in April for using in autumn and winter, and in August for

spring use, plants of the latter sowing being protected in severe

weather. The best sorts are Red-stalked, Yellow-stalked, and White (see

Fig. 223) or Silver Leaf.

=BEET CARRION BEETLE= (_Silpha opaca_). This destructive insect is

frequently found in dead animals, but often its grub almost destroys

the leaves of Beet and Mangold Wurzel crops. The grubs, which are black

and shining, when full grown are from 1/3in. to 1/2in. long; the three

segments next the head are rounded at the sides, but the other segments

are sharp, and the tail segment has a sharp spine on each side. "When

full-fed, the grubs bury themselves, and form cells at the depth of

3in. or 4in. below the surface of the earth, in which they turn to

pupæ, and from these the Beetle has been seen to come up in about

the space of a fortnight or three weeks" (Ormerod). The Beetles are

flattish, and about five lines long, brown-black, with a tawny down;

eyes large and oval; horns club-shaped; body somewhat oval; wing-cases

very flat, turned up at the outer edge, each case having three sharp

ridges running along it; tip of abdomen dull red. Any manures or

methods of cultivation that would stimulate growth in the plants, so as

to permit renovation of injuries, would be found useful. If farmyard

manure were applied to the soil intended for Beet _in the autumn_

instead of in spring, it would lessen the risk of attack to the Beets.

[Illustration: FIG. 224. COMMON GARDEN BEETLE.]

[Illustration: FIG. 225. DEVIL'S COACH HORSE.]

=BEETLES= (_Coleoptera_). Beetles form one of the most extensive

orders of insects, there being upwards of 3000 known British species.

They vary much in appearance, but a Beetle is readily recognised by

its front wings, or elytra; these form a tough horny sheath or case,

which lies over the real wings, and protects them when the insect is

not flying. Sometimes, the elytra are very short (see Fig. 225); the

mouth is fitted with jaws for cutting. The metamorphosis is complete,

_i.e._, the larva or grub is very unlike either the quiescent pupa or

the perfect insect. The period that elapses before Beetles arrive at

their perfect state varies from a few weeks to two or three years, but

is usually rather longer than in Butterflies or Bees. Various Beetles

attack growing plants and roots. Thus, _Otiorhynchus sulcatus_ and

_O. picipes_ attack Vines, Roses, and other plants, gnawing off the

bark. Some species of Beetles attack Mushrooms, while others bore into

the wood of old trees, or eat leaves (_e.g._ Turnip Fly), or burrow

in the leaves, or form galls on roots (Cabbage-gall Weevil). Of some

kinds, the beetles are hurtful; of others, the larvæ. Many kinds,

however, are beneficial, such, for instance, as the common Ground

Beetle (_Carabus_, Fig. 224), and the Devil's Coach Horse (_Ocypus

olens_, Fig. 225). These live upon other insects and snails. One kind

of Beetle--the Ladybird (see Figs. 226 and 227)--is very beneficial in

a garden, as it preys upon the aphides, or plant lice. For instructions

in dealing with the noxious kinds, _see_ =Asparagus Beetle=, =Bean

Beetle=, =Beet Carrion Beetle=, =Click Beetle=, =Cockchafer=, =Lily

Beetle=, =Rosechafer=, and =Turnip Fly=.

[Illustration: FIG. 226. SEVEN-SPOTTED LADYBIRD.]

[Illustration: FIG. 227. GRUB OF LADYBIRD. (Enlarged).]

=BEET= or =MANGOLD FLY= (_Anthomyia betæ_). The maggots of this fly

do considerable damage by feeding on the pulp of the Beet or Mangold

leaves. The eggs are small, white, and oval, and are laid in small

patches beneath the leaves; the maggots are about 1/3in. long, legless,

cylindrical, and yellowish-white. As it is of such recent appearance in

this country, specifics for its eradication are by no means numerous;

but, according to Miss Ormerod, "the best treatment appears to be to

nip it in the bud, where such treatment is possible, by destroying the

infested plants, but generally by all means of good cultivation, or by

special applications of artificial manure, to ensure a hearty growth,

which may run the plants on past the power of average attacks to weaken

the leafage to a serious extent."

=BEFARIA= (named in honour of Bejar, a Spanish botanist). ORD.

_Ericareæ_. SYN. _Bejaria_. An elegant genus of greenhouse evergreen

shrubs, closely allied to _Rhododendron_. Flowers bracteate; corolla

very deeply seven-cleft, spreading. Leaves racemose or corymbose,

crowded, quite entire, coriaceous. They thrive in a compost of peat and

loam. Propagated by cuttings, made of the young wood, and placed in

sandy soil, in gentle heat.

terminal panicles. July. _l._ ovate-lanceolate, glabrous;

branchlets smooth or hispid. _h._ 3ft. to 5ft. Georgia, 1810.

=BEGONIA= (named after M. Begon, a French patron of botany). ORD.

_Begoniaceæ_. A large genus of succulent herbs or undershrubs (a

few climbers), in many of which the stem is reduced to a tuberous

rhizome, whilst some are distinctly tuberous. Flowers usually showy and

large, white, rose, scarlet, or yellow, unisexual; perianth segments

petaloid, four to five divisions, rarely two. Stamens numerous,

filaments free or united at the base. Ovary inferior, styles two to

four, free, sometimes connate, stigmas brandied or twisted. Fruit

capsular, rarely succulent, often winged. Seeds numerous, minute.

Leaves alternate, more or less unequal-sided, entire, or lobed,

or toothed. Flower-stalks axillary, cymose. Distribution: Species

about 350, in all tropical moist countries, especially South America

and India; not known in Australia. Cultivated species (exclusive of

garden hybrids and varieties) about 150. A large number of genera,

or what were considered as such are now merged in Begonia--viz.,

_Barya_, _Baryandra_, _Casparya_, _Pritzelia_, &c. The rich colours

and beautiful form of the flowers of Begonias, their prettily-marked

foliage, and free-growing, free-blooming nature, have long marked

them out as favourite garden plants. Within the last twenty years a

new race, characterised by a tuberous root-stock, annual herbaceous

stem, and large handsome flowers, has been introduced from the Andes

of South America, from which, by means of careful cross-fertilisation

and selection, a large number of beautiful and almost hardy kinds have

been raised. The size, substance, and rich colours of the flowers of

the majority of the plants of this race of Begonias are witness to

what may be done by skilful cultivation and careful cross-breeding

among plants. In the same way the large-leaved, stemless section, of

which _B. Rex_ may be taken as the type and principal progenitor, have

been improved both in the size and the coloration of their foliage,

and countless forms are now in cultivation, both as garden plants and

for the decoration of rooms, &c. The propagation of Begonias may be

accomplished by means of seeds, which are freely produced by almost all

the cultivated kinds, by cuttings, by division of the rhizomes, and--in

the case of the large-leaved kinds--by leaf-cuttings. For the first of

these methods it is necessary that the seeds should be well ripened

before they are gathered, and kept dry until sown. Where it is desired

to increase any particular kind of garden origin, seeds are useless,

none of the hybrid or seedling forms perpetuating themselves through

their seeds, although equally beautiful sorts may be raised from them.

The characters of all true species are, however, reproduced in their

seedlings. For the successful raising of Begonia seeds it is necessary

to sow them on pans or pots of well-drained, light, sandy soil, which

should be well watered before the seeds are sown. The seeds should not

be covered with soil, or they will fail to germinate. Over the pans a

pane of glass should be placed, and they should then be stood in warm

house or a frame where a temperature of about 65deg. can be maintained,

and shaded from sunshine. As soon as the plantlets are large enough to

be safely manipulated, they should be pricked off into pans of light

leaf-mould soil, in which they may remain until large enough to be

placed singly in pots. Cuttings: These strike freely if planted in

small pots, in sand and leaf mould, and placed on a bottom heat of

70deg. Where large quantities are required, a bed of cocoa nut-fibre

in a stove or propagating frame may be used, and in this the cuttings

may be planted and remain until well rooted. Leaf cuttings succeed best

when laid on sand or cocoa-nut fibre, and shaded from bright sunlight.

In preparing the leaves, old, well-matured ones should be selected, and

incisions made with a sharp knife across the principal nerves on the

underside. They should then be placed on the sand or fibre and held

down by means of a few pieces of crock. Under this treatment, bulbils

will form on the lower ends of the nerves of each section of the leaf,

and these, when large enough, may be removed from the bed and potted.

With the exception of _B. Evansiana_ (_discolor_), an almost hardy

species from North China, all the shrubby species require a warm or

intermediate house for their cultivation, although during the summer

months a frame or sheltered bed answers for most of them, provided they

are removed into their warm winter quarters on the approach of cold

weather. Some of the species, such as _B. Dregei_, _B. semperflorens_,

_B. nitida_, _B. fuchsioides_, _B. Lindleyana_, _B. Richardsiana_,

along with the hybrids _Ascotensis_, _Knowsleyana_, _Weltoniensis_,

and _Ingramii_, are grown in pots out of doors all the summer, and

under liberal treatment they form large handsome specimens, which are

of great value as flowering plants for the conservatory in winter. The

tuberous-rooted herbaceous kinds should be started in heat in February,

and, when vigorous growth has commenced, be gradually hardened off,

for use either as bedding plants or as pot specimens for flowering in

the greenhouse. A mixture of loam and leaf mould with a little sand

and rotten cow-dung is suitable for the cultivation of these plants

in pots. Liberal supplies of water should be given during the growing

season. As the growth decays, water should be withheld until finally

the tubers may be shaken out of the soil and placed in dry sand or

cocoa-nut fibre, in a house or shed where a temperature above freezing

can be maintained. _B. gracilis_ and its varieties, _diversifolia_

and _Martiana_, are beautiful greenhouse plants, which thrive well

if treated as advised for the other tuberous-rooted kinds, with the

addition of a few more degrees of heat.

The _Rex_ section requires a light rich soil, plenty of moisture, and

a shaded position in a warm greenhouse. These kinds are often employed

with good effect for clothing peat-covered walls in ferneries, or as

an undergrowth in large tropical houses. Large specimens have been

grown under the stage in a warm house, the shade and moisture of such

a position being exactly what they best delight in.

_B. socotrana_, an interesting species from the island of Socotra,

is somewhat singular in its requirements. The stem is herbaceous and

annual, and about its base a cluster of bulbils are formed, from every

one of which a plant will be developed the following year. The growing

season for this species is from September to March, after which it goes

to rest for the whole summer. A tropical temperature and all the light

possible, are essential to the well-doing of this plant.

It is interesting to note the apparent impossibility to cross any of

the shrubby Begonias with the distinctly tuberous-rooted species; and

even the species of the shrubby section, whose stems are semi-tuberous,

have hitherto refused to commingle with the South American tuberous

kinds, of which _B. Veitchii_, _B. rosæflora_, and _B. boliviensis_

may be said to be typical. The infusion of the blood of these large,

handsome-flowered kinds into the tall, shrubby species, would

almost certainly result in the production of a race of splendid

winter-flowering greenhouse plants, and it is therefore in every way

desirable that no pains should be spared to break through the obstacle

to the union of the two races.
