CHAPTER IV

BULBS, CORMS, AND TUBERS

A TRUE bulb has a series of layers, or scales. An onion is a bulb, and

so is a Hyacinth; so are Lilies, though of a different kind. A Crocus,

a Gladiolus, and a bulbous Iris, are all corms. They are solid, and

could not be pulled to pieces in scales. A tuber is a thick fleshy root

that increases as the plant grows, and ripens when it has done growing.

Dahlias and Begonias have roots of this kind; so have many Anemones and

many wild flowers. Certain tubers are good to eat. You have one kind

for dinner whenever you have Potatoes, and another kind when you have

Jerusalem Artichokes.

Some people buy fresh bulbs every year, and pull up the old ones

directly they have done flowering. We think that if you are a

really-truly gardener, you will not wish to do this. You will want

to see some of your bulbs come up year after year, with increasing

strength and beauty; and you will want to take up others at the right

time, divide them or store them, as the case may be, and replant. But

if you do mean to grow your bulbs year after year and increase your

own stock, you must remember that for many weeks after the flowering

season you have masses of untidy-looking dying leaves. Therefore you

must plant as artfully as you can in places where other things will be

growing up close by and attracting attention. The leaves of bulbs must

not be removed until they are quite dead and come away with a touch,

and this does not happen until the summer sun has baked them for a long

time. While they are green the bulb is getting strength from them. We

shall only tell you about a few varieties that are inexpensive to buy

and easy to grow. When you have learned to manage these successfully,

you can try some of the many others you will find in catalogues and

in gardening books. Our advice to you is to spend your money on one

or two kinds every autumn, and not to buy a collection. This applies

especially to children who have a corner of a London garden, because

the collections always include some bulbs (such as Anemones or the

Persian Ranunculus, for instance) that are not quite easy to grow, and

would do nothing in the town border.

SNOWDROPS (GALANTHUS).

If you have any shrubs or trees in your garden, you can plant your

Snowdrops near their roots; and if they like the soil and the

situation, they will increase quickly. They are very fond of peat,

but they will grow well in any healthy soil, and they may be left

undisturbed year after year. There are many varieties. One of the

largest is Galanthus Elwesi, but it wants a sheltered spot and a light

soil. If you plant your Snowdrops in clumps near Crocuses and Winter

Aconites, put at least fourteen or fifteen in a clump, and set them

rather close together. The bulbs should not touch, but there should not

be more than the breadth of your thumb-nail between each. Beginners

nearly always set their bulbs too far apart, and then the clumps or

rows look stinted.

CROCUSES.

Another mistake that even older people often make is to think about

buying their bulbs about a month after they should have been in the

ground. There is a ‘best time’ to plant and a time that will ‘do.’ The

best time to plant spring flowering bulbs is the end of September. The

difficulty is to find places for them then, when your border is still

gay and crowded. But some of the summer flowers will be over, and can

be thrown away, and others will be cut down later, and can have some

bulbs tucked under the soil not far from their roots. Crocuses like to

be planted about three inches deep, and they may be left undisturbed

year after year. You could put clumps of them on your rockery or in

front of your border, and plant Siberian Squills, winter Aconites, and

Snowdrops near them. Then when April comes, you could sow Mignonette

or Nasturtiums just behind the dying foliage, and in time the summer

flowers would spread and fill up the bare places for you. There are

seventy species of Crocus, and many bloom in autumn. Some of these are

wild now in various parts of England, though they probably came long

ago from the Pyrenees. You will find the spring-flowering ones most

useful for your border; but though they are easy to grow, you have to

watch for their two enemies—mice and sparrows. Mice eat the corms, and

sparrows pull the flowers to pieces in order to get at the stamens,

that affect them as a sedative. It is generally found that they do not

attack the striped ones. If you are troubled by sparrows you must put

little twigs near your crocuses and wind black cotton from one to the

other. Crocuses seed themselves freely, and take from two to three

years to flower. You can also lift them in June, and separate the young

corms from the parent one; but you must not expect these very small

corms to flower the following year.

SIBERIAN SQUILLS (SCILLA SIBERICA).

The flowers of this little bulb are a most vivid sapphire blue, and you

should certainly have some either on your rockery or in front of your

border. They like a sandy loam, so if you have a clay soil you should

get some sand and plant your bulbs in it. Set them two inches below the

surface any time from July to September. They will increase if left

undisturbed, or you may lift the bulbs in June and carefully separate

the little offsets.

NARCISSUS, OR DAFFODIL.

If you buy bunches of these flowers you find that the man who

sells them to you calls some Daffodils, some Narcissi some

Polyanthus-Narcissi, and some Jonquils. But when you look at a

gardening book or a bulb list, you will find them all under the head of

Narcissi. There are hundreds of varieties, and some are difficult and

delicate, while others increase quickly in good soil. We fear that the

little London gardener will find that his Daffodils flower the first

year, and never send anything up again except green leaves; but in the

country the strong kinds, such as Emperor or Horsfieldi, have been

known to increase twentyfold in two years.

The best time to plant these bulbs is in August or September, but when

they are to replace summer-flowering plants they have to go in later.

Any good garden soil will suit the Daffodil, but a stiffish loam is

what it likes best. The bulbs should never come into direct contact

with manure, but if your soil is very poor you could have some dug in

nine to twelve inches deep. There is some diversity of opinion about

the depth at which to plant, but we have good authority for saying that

from two to five inches is enough. At St. Loy, the well-known Cornish

flower-farm, the manager believes, after many careful experiments,

that deep planting is a strain on the bulb, and weakens the growth. If

you are afraid of hard and prolonged frost, it is better to give your

Daffodils a winter blanket of manure, dead leaves, heather, furze, or

ashes, whichever you can conveniently procure. This must be removed

when the bulbs want to push through the ground. In June and July,

Daffodils lose both roots and leaves, and may be taken up for division.

The rule about division is quite simple. When you see a baby bulb

wrapped up to the neck in the sheath of the parent bulb, you must not

take it away, but plant them again together. It is only when the young

bulb has its own sheath that you may detach it carefully at its basal

root where it still touches the old one. When you want to separate

bulbs, do not tear them asunder. Press them gently together, and if

they are ripe for separation they will come apart easily.

When you have dug up those you want to divide, knock off as much soil

as you can, and leave the bulbs to dry for a short time in the sun, or

on a shelf in a shed or in a cool room. But it is advisable to plant

the young bulbs directly they are detached from the old ones.

If possible, when you replant your bulbs, give them a fresh place—or,

at any rate, fresh soil. When you cut your Daffodils, never cut many

leaves from one plant, because the bulb receives nourishment through

its leaves. The flowers may be gathered when in bud, and will come out

well and increase in size in water. Many people always send Daffodils

by post in bud, as they travel better, take less room, and last longer.

Besides, a mixture of fully-open and half-open Daffodils is like spring

itself, and gives you pleasure as they change and expand. But the

growers tell us that the shops and markets will not buy them in this

state, and insist on having the flowers in full bloom.

The Polyanthus-Narcissus has several flowers on one stalk, and it

is very fragrant. There are several varieties, and in the South and

West of England they are all hardy. In the sheltered parts of Cornwall

and the Scilly Isles they come into flower before Christmas, and all

through January you see fields of them opening their buds in the winter

sun. If you live in a cold part of England, you must give them a

sheltered corner and plenty of sand in the soil. Three good kinds are

Soleil d’Or, a bright yellow; Grand Monarque, white and pale yellow;

and Gloriosa, white and orange. The Polyanthus-Narcissus does better

than other kinds in a stiff soil, and it likes a little manure.

The variety of Daffodils in a bulb list is bewildering, but you must

learn enough about the leading kinds to choose, for instance, whether

you want a huge yellow trumpet, a hoop petticoat, a star, a double,

or one of those enchanting tiny ones that would get lost in a mixed

border, and must be given a choice corner in your rockery. In this

chapter we will give you the names of a few well-known and inexpensive

kinds that are effective in a mixed border. When you plant them in this

way amongst other flowers, you can put six in a clump, three inches

apart and three to five inches deep. They should be placed eighteen

inches from the path, well behind your Snowdrops, Crocuses, and dwarf

Alpines. You may like to choose those that flower late, and put them

near pale blue Hyacinths or deep orange Tulips. In that case, buy

Emperor, Empress, or Bicolor. The earliest trumpet Daffodil is Sir

Henry Irving; Golden Spur comes a little later. Bicolor Grandis is what

the catalogues call ‘the best all-round Daffodil’; Sir Watkin is ‘a

giant of noble appearance’; and Horsfieldi is pure white and yellow,

the finest of the early Bicolors. All these are single Daffodils.

The Poet’s Narcissus, or the Pheasant-eyed Narcissus, blooms later

than the Daffodils. These are what the flower-shops give you when you

ask for the single Narcissus, and they have strongly scented, pure

white petals, with a short yellow cup that is edged with red. If they

like your soil they will increase at a great rate, and if they don’t

they will flower the first year, but never again. We have known them

spread like a weed in a Yorkshire garden in a good rich loam, and we

have seen them doing well in pure sand. At Les Avants, in Switzerland,

there are vast fields of them, and when they are in flower the scent is

overpowering. They should be gathered just as the buds break, because

the sun soon bleaches the lovely orange and yellow of the ‘pheasant

eye.’

HYACINTHS.

Hyacinths should be planted nine inches deep and six inches apart. Five

or six bulbs of the same colour make a pretty clump, and they should

be from twelve to eighteen inches from the edge. You may leave them

undisturbed year after year, and in good soil they will increase and

flower. If you wish to take them up, you must wait till the leaves are

dead, and then dry the bulbs carefully in the sun before you store them

in sand till the autumn. The offsets, if cultivated in light, rich

soil, will flower in three years; but Hyacinths raised in Holland are

stronger than any you are likely to raise yourself. Until you are an

experienced gardener, we advise you to leave your clumps undisturbed as

long as they flower, and to buy new bulbs when you find that your old

ones seem exhausted.

GRAPE HYACINTH (MUSCARI).

These are charming little blue or white flowers, growing about six

inches high, and flowering in April. They are hardy and easy to grow,

but you must be sure to put a good many in a group, so as to get the

best effect with them. Plant them two inches deep and about two inches

apart. The bulbs are easily increased by lifting them every two or

three years when the leaves are dead, and removing the offsets. They

like any soil except a very damp one, and they look well in front of

your border or in your rockery, near some of the miniature Daffodils.

TULIPS.

Tulips are easily grown in any good garden soil. Where the land is

stiff and not well worked they die out. The proper time to plant is

from October till the middle of November, and, if possible, you should

give your Tulips shelter from wind, as their heavy heads, brittle

stems, and broad leaves are easily damaged. They should be planted

three inches deep. The ordinary garden Tulips may be roughly divided

into two kinds—early and late flowering—and of these there are many

varieties. The well-known scarlet and yellow Duc van Thol and all its

family are early, and will flower in April. The late ones flower in May

and June, and come from _Tulipa Gesneriana_. There are so many kinds

and colours in Tulips that we will not give you names, but leave you

to choose your own from any good catalogue. Perhaps you would like to

try some of the Parrot Tulips, which have large flowers, most curiously

coloured and flaked. Tulips, unlike most bulbs, may be lifted directly

their leaves turn yellow, dried in the sun, and stored in a dry, airy

place, where mice and rats cannot reach them. Most kinds are increased

by offsets. You can, if you choose, leave your Tulips in the ground two

or three years, but after that it is well to take them up and divide

them. If you do not, the bulbs get crowded, and do not flower well.

EARLY AND LATE FLOWERING GLADIOLI.

There are two kinds of Gladioli that we think you can grow in your

garden. One is the well-known Scarlet Brenchleyensis, that flowers in

autumn, and the other is an early-flowering dwarf variety called Nanus.

The early-flowering ones are white, pink, salmon, and crimson, and

in good garden soil they increase freely. They should be planted in

November, and you must remember that they will need protection from

frost during their first winter. Except in very hard weather, the

_established_ bulbs need no covering. They like a light loamy soil

and a sunny situation. When you have chosen a place for them, set the

bulbs, three inches deep and seven inches apart, in clumps of about

twelve, and have ready some dead leaves and ashes to keep each clump

warm. These dwarf varieties may be left undisturbed two or three years,

but as they increase quickly they will not flower well longer than that

unless you take them up, when the foliage is dead, and divide them. The

well-known white one, The Bride, belongs to this section.

The finest autumn-flowering variety is the splendid scarlet

one—Brenchleyensis. It is taller than the summer kinds, and should be

placed about the centre of your border. Each stem should be carefully

tied to a stick when it is about to flower, or a high wind may snap

it in two. This Gladiolus should be planted in the spring, about four

inches deep and twelve inches apart. When the leaves have died away

in the autumn, the bulbs should be lifted, dried, and stored in sand

for the winter. In the South and West of England the bulbs are often

left in the ground, but even there they should be protected the first

winter. Every two years they should be lifted and divided.

MONTBRETIAS.

A beautiful little South African flower, like a small Gladiolus. If

you live in a mild climate it will increase like a weed, and your

trouble will be to keep it down. In a heavy soil or where there is

much frost you must give protection. But the chief thing to remember

about Montbretias is that they will not flower unless the clumps are

frequently divided in autumn. Some growers recommend that it should be

done every year.

IRISES.

The Spanish and English Irises want conditions that not everyone can

give them. They like shelter without shade, drought in autumn and

winter, moisture in spring, sun in summer, and a light, friable soil.

If you have a light soil and a south wall, you should certainly put

some of these beautiful flowers in, and do not meddle with the bulbs as

long as the plants are doing well. Plant at least three inches deep and

five inches apart.

WINTER ACONITE (ERANTHIS HYEMALIS).

The Winter Aconite is welcome because it comes so early in the spring,

and even pushes up its bright yellow flowers, surrounded by a whorl or

ruffle of glossy leaves, through the snow. It will grow in almost any

garden soil, and is a good plant to put under shrubs or amongst ferns,

as it does not mind shade. It can be increased by dividing the tubers

in September; but if your Aconites do well, you can leave them year

after year and let them manage themselves.

ALSTRŒMERIAS.

These are beautiful orange-coloured Peruvian Lilies, and if you have a

light, well-drained soil you will find them easy to grow. If your soil

is heavy you must dig in leaf-mould, sand, and well-rotted cow-manure.

A warm, sheltered, sunny position suits them best. While growing and

blooming they should be watered sometimes, or the plants get too dry.

As they go out of flower you should remove the seed-heads, as when they

all set they exhaust the plant; but do not cut the stems or leaves,

because they are wanted to strengthen the tubers for the following

year. Their stems are so strong that they do not require stakes. They

should be planted from six to nine inches deep and twelve inches apart,

and once established, they should never be disturbed. When the young

shoots of the Alstrœmeria appear in spring, slugs must be kept away.

BEGONIAS.

Begonias used to be little grown in the outdoor garden, but of late

years you see them everywhere. We advise you to buy the inexpensive

unnamed tubers in April from any good nurseryman. When your Begonias

arrive you will find that they look rather like flattened, badly-grown

potatoes, and if you see no little pink shoots on them, you must put

them in a shallow box of sand or sandy soil or cocoanut-fibre, and set

the box on a dry light shelf till growth begins. If you can put your

box in a cool greenhouse, so much the better. The soil must be kept

just moist, but not wet, and the tubers must not be put out till the

spring frosts are over. In cold climates this will not be till the end

of May. When the time comes, choose positions in front of your border,

and as far as possible sheltered from high winds, which would play

havoc with their succulent stalks and broad, fleshy leaves. The soil

should be well dug, and if it is heavy you must add sand, and, when

you can get it, leaf-mould. Take up your tubers very carefully with a

trowel, so as not to injure their fine fibrous roots, and plant them,

with the pink shoots upwards, about four inches below the surface.

Then you must watch your Begonias carefully, and when they appear

above ground protect them from slugs by putting a circle of soot round

each plant. You will find Begonias useful as successors to the spring

bulbs that are over, and can be taken up for division or thrown away.

In the autumn they must come out of the ground before the frosts,

and if the leaves and stalks are not quite dead, cut them off with a

sharp knife; never pull at them, or you may injure the tuber. Some

growers keep their tubers exposed in a light, airy greenhouse until

the stalks and stems are so shrivelled that they will drop off with a

touch. As long as they are not shrivelled, they constitute a danger to

the tuber during its time of rest. Begonias must be stored in sand or

cocoanut-fibre in shallow boxes, and kept in a frost-free place through

the winter. They can be grown from seed or from cuttings under glass,

but we think both operations are a little beyond the juvenile gardener.

DAHLIAS.

It is difficult to find room for Dahlias in a very small garden, but

even one will give you a great deal of pleasure if you manage it well,

as the flowers go on for a long time, and are most useful for cutting.

Whether you have one or more, you must remember that the Cactus Dahlias

grow from four to six feet high, and that each plant makes a big bush.

The pretty little Pom-poms are rather shorter, and can be placed in

front of their big brothers. We advise you to grow these kinds, and

not what are called show varieties, which are stiff and, we think,

ugly. Dahlias are greedy feeders, and wherever you mean to plant one

you should get someone to dig in manure eighteen inches down. About the

end of April or early in May, according to the season and your climate,

you put out your Dahlias. If they are spring-rooted cuttings in a pot,

all you have to do at first is to take them out of the pot, plant them,

and look out for slugs. They will devour every one if they can. If you

are given a tuberous root, you must put it five or six inches deep in

the ground. It is of no use to grow Dahlias unless you can stake and

tie them properly, as they become very heavy, and are ruined by a high

wind if unsupported. Stout, square green stakes are made on purpose

for Dahlias, and if you are far away from a town where they are to be

had, you must get someone to cut and point you natural ones equally

strong. For Cactus Dahlias they should be five or six feet long, and

for Pom-poms four feet; and at least one foot of this length must be

driven firmly into the ground. Do not tie with raffia, but with stout

cord or coir, as nothing else is strong enough. When the frosts come

you can take up your Dahlias and store them in a dry cellar; but unless

you have a gardener to help you, we do not think you could strike

cuttings from them in heat, in spring. You will find in autumn that the

little plant you put out of a pot in May has made a big tuber, with a

number of fingers. These should be left as they are till spring comes

again, and then they may be carefully separated with a sharp knife and

put as they are into the ground. Each piece will make a fresh plant. In

sheltered parts of Devonshire and Cornwall, Dahlias, after being cut

down, are often given a little covering of straw and manure and left in

the ground.
