INTRODUCTION
I have grown pears, plums, cherries and mulberries for many years, and have written many articles about the first two fruits; yet, in preparing this work, I found that I had still much to learn, and I wish particularly to express my obligations to the new edition of Thompson's Gardener's Assistant, edited in six volumes by Mr Watson, Assistant Curator of the Royal Gardens, Kew, and brought out by the Gresham Publishing Company. I have also derived valuable aid from the volumes of the Royal Horticultural Society. The chapter on "cherries" is based chiefly on the booklet contributed by Mr G. Bunyard to my Helpful Hints for Hard Times published by the S.P.C.K.

History of the Pear
The Pear is my theme, and a pleasant one it is. Only those who have planted trees, pruned them, watched their growth, plucked the fruits, enjoyed them at almost all hours, seen them on the table month after month as an appetising dish, can fully realise the value of the Pear. A good Pear-tree is like a faithful friend—treat him properly and he will
Pyrus (or pirus), the Latin name for Pear-tree, is the name of a genus of plants belonging to the natural order Rosaceæ. Pyrus communis, the wild pear, from which the numerous cultivated varieties have sprung, is found over a great part of Europe and Asia, within the limits of the temperate regions. Its origin is lost in obscurity. The lake-dwellers in Switzerland are said to have stored the fruits for winter use. It was probably brought by the Greeks, possibly by birds, from Asia, and after a time became a favourite with the Romans as well as the Greeks. It is mentioned by Horace, Vergil, Juvenal, and others. Pliny refers to numerous varieties, describing those with special flavours. He tells us that many of the sorts were called after the countries from which they came, such as the Syrian, the Alexandrian, the Numidian, and the Grecian. Thus he mentions pira nardina, a pear with the scent of nard; pira onynchina, a pear of the colour of the fingernail, and others. These last are evidently Greek. Forty or fifty sorts are named in Roman writers, and the Pear was appropriately dedicated to Minerva, the goddess of wisdom.
The Romans no doubt took their pear-trees northwards into Gaul and Britain. The climate of France is so well adapted to the growth of pears, that at one time it was thought all good pears must come from France. I well remember many years ago seeing a garden in this country full of pear-trees, every one of which had come from France. Happily there is no need now to go out of England for the very best varieties. A list published in 1628 by a fruit-grower of Orleans named Le Lectier (there is a new variety called by his name, and probably after him) enumerates 260 varieties. The well known Jargonelle is mentioned in that list. Our Parkinson in 1629 refers to 64 varieties only. Seventy years later we read of 138, and in 1829 of 630 varieties. John Scott, rather famous as a fruit-grower forty years ago, says in his "Orchardist" that he has above 1000 sorts worked upon the Quince Stock. He had studied pomology at the "Jardin Fruitier," the fruit garden attached to the Jardin des Plantes at Paris, and, using his opportunities, learnt all the secrets of Pear culture, and brought them from France to Merriott, near Crewkerne, in Somerset. The last edition of Dr Hogg's "Fruit Manual" (invaluable to the Pomologist), published in 1884, contains the names of 647 varieties. Not a few of these were marked as worthless by the Committee of the National Pear Conference, held at Chiswick in October 1885. The Royal Horticultural Society in their "Fruits for Cottagers and Small Farmers" (1892), selected eight varieties only for eating, and two more for late keepers; four were recommended for cooking or stewing. Fresh sorts are constantly being brought into notice, the result of cross-fertilisation, and we may, I think, congratulate ourselves that British pears in a favourable season are as good as those produced in any part of the world. Let any one who doubts this statement attend a Crystal Palace or any other first-rate Fruit Show; his doubts will soon be dispelled.
Situation and Soil
These two points are of the greatest importance in successful cultivation. No amount of skill will enable even a clever gardener to grow good fruit in a bad site. Where the land is low and swampy, exposed therefore to frosts more than ground at a higher altitude, the effort would be useless. Stagnant water moreover produces canker, and soon ruins trees. Pears love a deep moist soil, but not water that lies for any length of time about the roots. On a hillside, where the slope is more than gradual, so that in a dry season the upper part suffers from drought, they would be a failure. Trees planted near the bottom and properly protected from winds might succeed, yet they would probably suffer from frost. The slope should not be more than two to three feet in a hundred.
The aspect should be south, south-east or south-west. The Pear is of Eastern origin, and probably retains its Eastern habit in blooming early some time before the apple. It needs more warmth, and more protection.
To plant pears in a north aspect even on a wall is a mistake. Morello cherries are a sure crop, pears a very doubtful one. The wood is not well ripened, and bloom-buds are not often formed. The amount of rainfall is also a matter for consideration. If the soil is light, more moisture will be needed than in heavier land. Heavy clays are not good for pears, yet much may be done to improve such soils, and some outlay may be desirable in gardens and small plantations. Good drainage will be necessary. The ground before planting must be well lifted and exposed to the air; some portions should be burnt and mixed with the rest; decayed vegetable matter should be added in abundance. After planting, when the trees are rooted and growing, the soil should be often lifted with a light fork, or hoed, and the air admitted to the roots. A clayey loam is the best of all soils for the Pear, yet even that may be much improved by exposure before planting, and the use of the fork or hoe afterwards. In sandy or chalky soils, pears will have a poor chance even on the free (or pear) stock, unless the ground has been previously prepared by trenching, and then digging in a good quantity of decayed stable or farmyard manure. Marl or clay from other parts, or turf (chopped up) from a field, may be added with advantage. Generous treatment subsequently in the way of liquid manure will alone make trees in such ground a success. Should, however, the soil be shallow and the subsoil gravel or chalk, trees must be lifted every few years, and the expense in a large garden might be considerable.
The monks in olden days were wont to put slates or large stones below their trees before planting, to prevent the tap-root running into bad soil. In modern gardens a concrete bottom two or three inches thick, sloping towards a drain in front, is sometimes made. Methods must depend on soil and means. A concrete bottom is better than a stratum of stones or brick rubbish. Persons content with a few small trees may lift them frequently or root-prune annually, in which case no special precautions are required.
Protection
As the Pear needs sunshine and warmth as well as moisture, it must have protection from cold winds. Walls and buildings are not always to be had. Black Italian or Canadian poplars well planted and rather close together soon form a good shelter; limes (invaluable for bees) quickly make a good fence if encouraged to throw shoots from the lower part of the tree and closely cut in. Hedges of damsons or the myrobalan (the cherry plum) serve as shelters from the wind and grow rapidly. This cherry plum blooms early, and its flower is often cut off; otherwise its fruit (ripe in August) is useful for tarts. Protection is needed on the south-west against the winds as well as on the north-east. The larger trees should be placed at some distance that their roots may not absorb the nourishment needed in the fruit garden.
Planting
seems a simple subject, yet the difference between good and bad work may make the difference between success and failure. Proper planting is of vital importance. The ground should be prepared beforehand. If it is wet, and the water does not readily pass off, drainage is essential. The depth of the drains must depend on the outfall. If they can be sunk three or even four feet below the surface, they are less exposed to danger from deep
With pears on the Quince, it is important that all the quince stock should be covered by the soil, as it suffers in dry weather if exposed, and the fruit would therefore be affected. All buds on this stock should on this account be inserted as near the ground as possible. Should the soil be very heavy, yet pears must be planted, place the roots almost on the surface, and throw the lightest earth obtainable round the stem. If such ground is trodden down hard, and rain should soon follow, the ground would probably become like a brick, and the roots, kept in check, would suffer seriously.
The best time for planting is towards the close of October and in November. Select your trees yourself, and go only to first rate nurserymen for pears if you want varieties on the Quince stock. Each nursery has its specialty. Budding, grafting and double-grafting on special stocks do not always have the attention and skill required. If you cannot go, send your orders early, so as to secure an early choice and good trees. Planting may continue to the end of February, but you must not expect good trees for late orders. The roots, too, make some progress even in winter, so that early planting is preferable in every way.
Staking and Wiring
Standards should be attached to a round, strong, stout stake 2½ inches thick or more, as soon as planted. The best plan is to have the stake in position ready for the tree. For full sized standards, the stakes should be 7 to 8 feet long, and driven 18 inches or more into the ground; they should be in the centre of each hole. Choose durable wood, as far as possible. A straw or hay band, or a piece of bagging, should now be run round the stem, and the stake attached to it by thick string or cord well tarred. The twigs of the willow (soft and strong, especially the golden willow) may also be used. Protection against rabbits must be provided at once. A wire fence round the orchard or garden is best; where there is no fence, put a yard of wire netting (1¼ mesh) round each tree. This will last for years. The wire should be 3 feet high at the least. Examine your fence every year in September and repair. You cannot be too particular. Serious damage may be done in a night.
Stocks For Pears
The discovery of the Quince Stock, as adapted to the Pear for budding or grafting upon, has added immensely of late years to the popularity of this valuable fruit. The discovery, it is true, is not a new one. Merlet, writing in 1667 (says Mr Scott), recommends the Portugal Quince as stronger and more favourable for working pears upon than any other variety: "It swells equally fast with the graft, which none of the other sorts do." Le Gendre, an author of about the same date, in Le Manière de cultiver les arbres Frutiers, says: "I have been much aided by the invention of grafting the Pear upon the Quince," and adds that he was one of the first who helped to introduce this method. By this discovery the well-known saying: "Plant pears for your heirs," must give way to another:—
Grow fruit for their heirs
Is a maxim our grandfathers knew;
But folks have learnt since,
If you graft on the quince
The fruit will develop for you."[1]
This stock checks excessive growth, and brings the tree into early bearing. It is not adapted for large standards nor for light soil; in good pear ground it is simply invaluable. Sometimes poor results occur, but the failure is usually caused by the want of proper care, either at the nursery or in the garden. Young trees are often overworked. Some varieties will not thrive on the quince stock, so that double-grafting has been introduced. Thus the strong-growing Beurré d'Amanlis is grafted on the quince, then two years after some other sort is grafted on it. It is said that in this way Gansel's Bergamot is made "a marvel of fertility,"[2] but this is not my experience! The disappointing pear Marie Louise is usually double-grafted, so is that excellent late pear Josephine de Malines for cordons, bushes, or pyramids, and so are many others. Strong-growing varieties like Vicar of Winkfield, Beurré Hardy, Beurré Clairgeau, Marie Louise d'Uccle, and others, are used as intermediate stocks. To check the vigorous Pitmaston Duchess, the weakly Winter Nelis is employed as an intermediary. Our chief nurserymen are studying the habits of each pear which needs double grafting, and failure is rare on their part. Fruits grown on the Quince Stock are often more highly coloured, and not so coarse as such as are on the Pear Stock. Those who have a good pear soil then should plant no tree on the Pear Stock, except in an orchard.
The varieties usually employed are the Portugal, the Angers, and the common Quince. The Angers being compact, prolific, and easily increased, is said to be the favourite.[3]
In some soils Pear Stocks must be used. The Quince would not thrive; it is not strong enough. The latter is surface rooting, it emits more fibres, and does not rejoice in the tap-root of the Pear Stock. But for light and unfavourable soils, and also for
Orchard Trees
In good soil and a favourable, well-sheltered aspect, standard trees on the pear stock may be a success if planters and owners can wear the cap of patience for eight to ten years. Should it be probable that cattle will use the ground, a strong and lasting fence must be put round each tree, as thorns encircling them will not suffice. Iron fences made for the purpose, with wire netting added at the top, may be the cheapest in the end. Otherwise, put three posts (larch or oak) to form a triangle round the tree. These should be well charred or tarred at some distance from the lower end before being firmly driven in. The tops should slant outwards. Then nail cross-pieces to the posts; old railway-sleepers are sometimes cheap and useful. The standards in good soil should be thirty feet apart or more. It is a mistake to allow the grass at any time to grow under the trees. Moisture which pears require is absorbed, and the air is kept from the roots. Reduce the branches after planting (in October or November) to five or six at the most; cut these back to an outer eye, six to nine inches from the stem. The roots will establish themselves for the first year, and good growth will usually follow. The strength of a tree depends mainly on its roots. These must not be overtasked at first, or the tree will suffer seriously. Next year, late in July, cut back to the sixth leaf all shoots springing from the main branches which run inwards; keep the centre open, well exposed to the light, sun and air, and allow the main branches to develop themselves freely. In the winter cut all shoots not needed back to two or three eyes. If more boughs are needed, shorten the leading shoots, always cutting just above an outer eye. Make the tree as even as you can by shortening leading shoots on opposite sides. Never allow boughs to cross or to interfere with one another. If boughs are void of a fair proportion of shoots and spurs, they should be stopped. Be careful to admit the sun fully on the south side. Cut off all shoots springing from the central part or on the lower part of the branches of old standards. If young standard trees are well planted, carefully fed and pruned, the stems kept clear of weeds and grass, they can be brought into comparatively early bearing. Where irrigation is possible, let a stream of water that has flowed some distance over the ground be turned in dry weather on to their roots, or let liquid manure be given after rain; the effect will be surprising. But beware of very cold or stagnant water!
Early pears are probably the most profitable for orchard planting. The following are reliable:—
Six Market Orchard Standard Pears selected by Messrs Bunyard: Hessle, Fertility, Williams' Bon Chrétien, Beurré Capiaumont, Durondeau, Pitmaston Duchess.
Messrs Rivers' list of seven: Beacon, Bon Chrétien, Clapp's Favourite, Fertility, Conference, Marie Louise d'Uccle, Vicar of Winkfield.
The list of an eminent firm in the south is as follows:—
Bon Chrétien, Hessle, Pitmaston Duchess, Louise Bonne of Jersey, Emile d'Heyst, Marie Louise. At the Pear Conference (R.H.S.), 1885, Bon Chrétien had 50 votes, Louise Bonne 46, B. Capiaumont 38, Hessle 30. Thus, William's B. C. has 4 votes, Hessle 3, Pitmaston 2, Fertility 2. Personally, I prefer Pitmaston as a bush, the fruit being so large. It is a pear for a good market, not a coster's fruit. Ten trees of three varieties would make a good orchard. Vicar of Winkfield or Verulam might be added for a later Stewing Pear. The bloom of Marie Louise is so tender that I prefer Marie Louise d'Uccle, a very good cropper; the fruit is sometimes sold as Marie Louise. The list of 1885 is hardly up to date. Louise Bonne does not do well with me as a standard, and I should substitute Fertility. Clapp's Favourite is also very promising.
If the plantation is of any size, do not put two trees of the same variety close together. Some varieties are self-sterile, yet quite capable of cross-fertilisation from the pollen of other varieties. Bees should be kept close at hand to fertilise the blooms.
The following is Mr Radcliffe Cook's list of orchard standards for Perry (see his "Cider and Perry"):—
Barland, Moorcroft, Red Pear, Taynton Squash, early varieties.
Langland, Yellow and Black Huffcup, midsummer.
Blakeney Red, Butt Pear, Oldfield, Pine Pear, Rock Pear, late.
It is said that in France there are more than 1500 varieties of Perry Pears. We must "wake up" and grow the best varieties.
Pyramids
No one should plant high standards except under special circumstances; pyramids are a part of almost every large and good fruit-garden. In moist, strong soils they should be on the Quince Stock. In light soils the Pear Stock alone has a chance. Some trees succeed only as bushes, others can be trained as pyramids. The lists of the leading nurserymen usually refer to the habits of each tree. Buy trees trained as pyramids direct from the nursery. If you prefer maidens (trees one year old) train as follows: In early spring, after planting, stop the tree slightly, and encourage growth; next winter cut it down almost to the stock. A strong shoot from the base must now be made the leader and the central stem. Next winter cut this back to within 18 inches of the ground. The highest shoot next season must be trained upwards by a straight stake; the side shoots will form branches. These in September must be brought (by stakes) into a horizontal position. The stronger must be more depressed, the weaker may be left for another year. Bend into position before the sap sinks. In winter reduce side shoots on branches to two or three eyes. Cut the leading shoot 12 or 15 inches (according to growth or soil) above the branch below it, so as to produce fresh branches. Bend these down as before. As the tree progresses, the leading shoot may be stopped in summer when it has grown a foot, so as to throw out more branches; it may grow another foot upwards by September, and also send out fresh branches. Every care should be taken to keep an upright and straight stem. In summer pruning check the upper branches before the lower, stopping the terminal shoots so that they shall not spread out further than those below them. Stop them when they have grown 8 or 10 inches, removing the top. Any shoots from the branches (laterals) must be reduced to six or seven leaves about mid-June (on young trees), so as to open the tree and concentrate growth on necessary parts, and also to produce bloom-buds. These may form near the base. In winter reduce to two or three eyes.[4] Pyramids on the Pear Stock in strong soil reach a height of 15 to 25 feet, but such trees are hard to manage. Weak growing sorts might be tried. The larger trees would need annual root-pruning (half a side each year) to secure good crops. Train pyramids from the nursery in a similar way, keeping the upper branches in subjection to the lower, taking care to let light into every part of the tree by summer pruning. Pyramids on the
The following are good sorts for pyramids:—
Citron des Carmes (on pear) early, Williams' Bon Chrétien, Clapp's Favourite, Marie Louise d'Uccle, Duchesse d'Angoulême, Durondeau, Fondante d'Automne, Beurré Hardy, Beurré Superfin, Maréchal de la Cour, Doyenné du Comice, Princess, Josephine de Malines, Beurré Rance.
Cooking Pears.—Bellissime d'Hiver, Vicar of Winkfield, Verulam.
Others might be added. Some of these also do well as bushes.
Columnar Trees
are pyramids on a smaller scale, kept well in check by lifting or root-pruning, more like a column than a pyramid. In light soil this work would not be needed. They are adapted for small gardens, and, well managed, may be very useful. Plant from 8 to 10 feet apart.
Espaliers
in the open ground (according to some good growers) are the most economical of space, but I do not care much for them. Train at first from maidens as for a pyramid, keeping one upright shoot and guiding one branch each side in an almost horizontal position. Cut back the leader once a year at first at about 12 or 15 inches from the branch below to one bud just above the buds whence the branches are to spring. From this one bud the upright leader will grow. The branches should be about a foot apart. Stop the topmost in summer (if very strong) to divert the sap into other parts. Stop strong horizontals to strengthen the weak and to promote fruit-buds. Stop shoots on the branches late in June or in July at six full leaves, if the tree is flourishing, but not otherwise. Equalise the sap as far as possible. Espaliers may be bought from the nurseries, saving several years. Plant 15 or 20 feet apart according to ground and tree. Support with rails or stout firm stakes placed 2½ feet from the walk; place the tree 3 inches from the stake on the side of the path. Keep the trees low to prevent shade on the garden; 5 feet is high enough. Prune established trees in July; cutting back fresh shoots (laterals) to six leaves, and opening the tree and fruit to the sun, removing shoots not needed. Reduce to two or three buds in winter; with a small saw cut back large lumpy pieces the growth of years.
Horizontals on Walls
should be trained as Espaliers. They are better for a low than a high wall. The branches should be about a foot (four bricks) apart. In some old gardens, enormous Horizontals may be seen with the branches at distant ends turned upwards. The lower branches are horizontal as far as the space allows, then turned upwards. This change checks the sap, lessens luxuriance, and promotes fruit-buds. But there often is excessive growth in the upper parts. These upper shoots must be pruned before the lower. Such trees are called Palmetto Verrier, and are scarcely to be recommended.
Fan-Shaped Trees
are adapted to high walls. Tomatoes or other fruits may be grown below in the vacant spaces. By planting a standard against a high wall, it will soon be covered if fed and duly trained. Cut the tree back as an orchard standard after planting. Keep the boughs well away from each other, 12 inches or more apart. If a wall is shaded with foliage it derives little heat from the sun. Stop the gross upright shoots early in the season to spread the sap, and summer prune in July. Keep the branches close to the wall, and complete pruning in winter. These trees must be on the Pear Stock. The choicest sorts, such as Doyenné du Comice, Beurré Superfin or Diel should be selected for a south wall. Prune the upper parts before the lower. Wires may be placed on the walls 1½ inches out, with an interval of 12 inches or more between each wire.
Bushes
are of great value, either in a plantation or a garden. In good soil, even those on the quince grow large, and may need root-pruning or moving. In poor soil, with gravel or chalk not far below, bushes on Pear Stock must be moved every few years, and well fed. Rotten manure given in the autumn will attract and feed the roots. Fruit on low bushes is less affected by strong winds. Some sorts do better as bushes than as pyramids; bushes, too, are more under control. A maiden tree after planting should be allowed to grow for a year unchecked, to establish the roots. In winter cut the tree back to within a foot of the ground. In the spring it will throw out vigorous shoots. Select three or four of these, and fix them in position with stakes, removing the others. Next winter cut these back to an outer eye, leaving six or nine inches of each branch from the stem. Other branches will soon follow. Time will be saved by buying bushes from the nursery. Keep these as open as possible, especially on the south side and the centre. Each branch should be a foot apart. Summer prune in July and winter as before. Stop the branches in summer, if growing rapidly, to produce fruit spurs, and in winter cut back to strong wood (to an outer eye). All new wood will thus be feathered during the following year. Some bushes are very diffuse and need much room, e.g. Catillac and Uvedale St Germain. Bushes on quince should be eight to twelve feet apart; strong growers, such as Pitmaston, Duchesse d'Angoulême, Catillac, should be even more in good soil, if root-pruning is not to be practised. The following are good as bush trees:—
