THE basket willow is one of the little known farm crops which cannot be too highly recommended. The farmer is compelled more and more to branch out into some special lines of farming in order to avoid competition and at the same time secure the highest possible returns from his land. He is also compelled not only to cul- tivate rationally and intensively the most fertile acres of his farm, but also to l)ring under cultivation the least fertile acres and render them productive to the fullest extent. The basket wdlow is one of the easiest of all the farm crops to propagate. Its management is simple. rt([uiring no machinery of complex mechanism, or a great deal of high-])riced labor. Almost all the work required in rational basket willow culture comes during a time of the year when other farm work does not claim the attention of the farmer. He is able, therefore, to give constant emjiloyment to his farm hands all the year. The reason why basket willow culture has received so little atten- tion in this country is due partly to the lack of knowledge and partly to the mistrust of new things. Every farmer who is eager to get the most money from his farm, as well as to enchance the value of his land, should give willow culture an unprejudiced consideration. In- vestigation will convince him that this is a product of the farm of which an over production is absolutely out of the question for many years to come. There are few cultural plants which yield suoh a good crop in return for so small an outlay of capital and labor. The demand for basket willow rods is very great and every year many thousands of bundles of rods, as well as large quantities of manufac- tured basket willow ware, are imported from France, Germany and Holland. The growing of this product is so quick and easy that it seems incredible that the industry has not been miore fully developed, or more generally introduced. There is a constantly growing de- mand for willows, sufficient to take care of a largely increased production. SOIL REQUIREMENTS. One of the first considerations in the cultivation of basket willows is the selection of the proper soil. Willows do not thrive in all soils. Though they do not require a wet soil, as is often supposed, they do 6 • require one which is permanently moist. Soil which produces a good crop of wheat may also yield a fair crop of basket willows when properly managed. It is best to select moderately loose, moist, loamy sand land. The loam contains the necessary nourishment for the plants and retains the moisture, while the sand mixed with loam keeps the soil loose and the roots can penetrate quickly and easily in all directions. Areas which are low and swampy or subject to fre- quent flooding must be drained so that the water does not stagnate or the soil become spur. The soil should be deep, with a water level preferably not over 6 feet below the surface. It was formerly supposed that basket willow growing could not be profitable on land having a high rental value. It has been shown conclusively, however, that basket willows grown under intensive management and in rich soil yield a return equal to or greater than that of most farm crops. On the other hand, very poor soil may be planted with basket willows, provided the proper varieties are select- ed and the soil is sufiiciently fertilized and irrigated. One cannot grow basket willows successfully on dry, shallow soil or on perman- ently wet and boggy peat land. Locations where frosts are liable to occur during the growing season should be avoided since the tops of the tender young shoots are easily injured. PREPARATION OF THE GROUND. . Draining, wherever necessary, must be attended to at once. The drains should be straight and open from the lowest part of the ground, giving them a depth of two or three feet, according to the conditions. They should be about 5 yards apart in wet, and ten yards in moderately wet ground. The land should be plowed as deep as possible in the fall prior to planting in the following spring. The object of the deep plowing is to turn the top layer of the soil completely under and in this way bury the weed seeds in the surface soil so deep that they cannot spring up during the following season. The soil does not settle or become compact during the first winter, but becomes thoroughly pulverized by repeated freezing and thaw- ing. The depth to which the soil should be turned depends some- what on the soil and subsoil. For a sandy soil, which is naturally loose and porous, a digging of 10 to 12 inches is sufficient. Where the soil is compact and contains heavy clay a digging of 15 to 18 inches is necessary. Prior to plowing, the area should be thoroughly cleaned of all its rubbish and weeds. It is advisable to plant the area to potatoes the year before willows are planted, so that the soil be- comes thoroughly pulverized during the cultivation and digging of this crnp. It is essential iliat weeds are ke])t down, and tlieref<:)re thev nuist not be allowed lo come to seed. In IcK'ations where the soil is poor it is best to spread well-rotted stable manure over the surface just before plowing. Lime is recom- mended for soil which is chiefly composed of sand.

A great many kinds of basket willows have been in- troduced into this country from Europe, but only a few have proved worthy of cultivation. Those most commonly jilanted in the L'nited States are American green. Welsh, Lemley, and common white. It is not always wise to plant extensively the most highly recommend- ed varieties until they have been tested on the particular area to be planted. Each variety has its special requirements and unless the soil constituents and soil moisture are definitely known great care is required in the selection. Sali.v aiiiygdalvna — American green. This willow requires a moderately rich sandy loam, in which it frequently produces rods from 8 to lO feet high in a single season. The rods, although heavy at the base, grow very tall, straight, and flexible. It produces a higher yield in weight per acre than any other variety and is often considered the most profitable for general use. Salix ['urpurca — Welsh. This willow grows in a great variety of soils, and produces rods of excellent quality. In rich loam it crops heavily and the rods grow very slender, straight, and cylindrical. and seldom produce side branches. The Welsh yields less in bulk per acre than the American green, and surpasses it in market value and in the quality of the rods. This willow^ has the highest specific weight. For planting along shallow river banks, where ice or high water is apt to do some damage, this willow^ recommends itself more particularly than any other. Salix priiinosa acutifolia — Lemley. which is also known as Casp- ian willow, is a good cropper in rich, fresh loam. L'nless the stools of this variety are planted close the rods develop side branches near the top, especially during the first few years of the life of the holt. Lemley has been reported to thrive very well in loose, sandy soil with a moist loamy subsoil. It demands a very rich soil when the rods are cut ofif every year. Salix z'iininalis — Common white. This willow has been planted rather extensively and with good results in some sections of the United States. It produces a great many new shoots every year, and 8 the rods are extremely tough and almost perfectly white after peel- ing. By correct handling the holt may last many years with only a slight decrease in the crop as the stools become older. This willow thrives in a great variety of soils but demands a considerable degree of soil moisture. Sali.v purpurea viminalis — Blend willow. This is one of the earl- iest and best basket willows cultivation in North Germany and is now introduced here with success. It produces beautiful, slender, and branchless rods which are both smooth and cylindrical. The first year's rods are generally curved at the base, but the second year and thereafter they grow up straight. The pith is considerably smaller than in those of the Welsh, and the rods are more flexible. There is no basket willow which produces more rods per stool than this one. The stock is valued very highly both in the peeled and un- peeled conditions. The blend willow thrives in rich, sandy loam with a moderate degree of moisture, but it does not grow in wet soil. Salix Americana — American willow. This willow is said to have had its origin in the United States and has been cultivated in eastern Germany for a number of years. It has large and glossy leaves and a pinkish stem. The rods are smooth and slender and are considered among the best for the production of peeled stock from which the best grade of wicker work is made. The American willow is seldom attacked by insects, and for this reason may prove to be the basket willow of the future. It requires a moderately rich, moist soil. There are other varieties yielding good results only in limited sec- tions of the country where local conditions are favorable. It is im- portant to select varieties possessing the most desirable qualities and at the same time fitting the local soil and climatic conditions. Those above mentioned usually give the best results in this country. Many common names are used for the same varieties of willow in various parts of the country. This confusion of vernacular names is unfortunate and an attempt is made here to give the name most generally used for each variety. PREPARING AND STORING THE CUTTINGS. Basket willows are propagated on a commercial scale wholly by cuttings. The best time to prepare the cuttings is during the last half of February or the first half of March. It is best to select them from the shoots of the most thrifty stools and only from one-year- old rods. It has been the experience of a great many growers that cuttings of one-year-old rods produce roots and shoots more quick- ly and easily than cuttings from older wood or from rods cut from 9 weak stools. Althous^li it is j^onerally atlvisablcj to have the cuttings prei)areh(>nl(l be allowed to gTOvv up. This crop may then be plowed under, which will not only serve a.s a very g-ood fertilizer but will also keep the soil loose and moist for several years. Fertilizing old plantations frequently becomes necessary in order to prolong the life of the holt. Well-rotted stable manure should be spread broadcast over the bolt immediately after the willows have been cut. Great care should be taken to use manure free from weed seeds. Fertilizers containing phosphoric acid are very highly recom- mended. The quality of the rod in old plantations is considerably improved when this fertilizer is used. \ 11 A LIT \' OF rm-: holt. The length of time during which a willow plantation yields a profitaible return to the owner depends upon a number of things : variety, soil, drainage, climate, preparation of the ground, fertiliz- ing, irrigation, or soil moisture, care and cultivation of the holt, manner of cutting the shoots, and the protection of the holt from winds, animals, or insects. The duration can be easily prophesied when one is familiar with these factors. Under favorable conditions a holt should last irom i8 to 25 years. As soon as the production is considerably diminished on account of the loss of vitality in the mother stools, it becomes necessary to grub them up. A crop of corn or wheat should then be raised on the area before it is again planted to willows, but it is best to select a different variety of wil- low from the one originally grown in the holt. It is claimed by expert growers that the profitable life of a holt may be increased by allowing the willows now and then to grow for two years without cutting them. RESTOCKING OPEN PLACES. Although willow growers realize that it is absolutely necessary to plant in places where stools are missing, they very seldom attend to it with sufficient care. The vitality and productiveness of the holt depend largely upon the proper replacing of dead and decrepit stools with vigorous new shoots. Every year a number of stools die from insect and fungous diseases, or from injuries inflicted while cultivat- ing the holt. Stagnant water or an insufficient amount of soil mois- ture frequently causes stools to die. It is best to grub up all the un- productive stools every year and plant in their places thrifty new shoots. This may take place any time from late fall until the middle of April. For this purpose ordinary short cuttings should not be 12 used, ibnt entire one-year-old rods, which must be vigorous and branchless. The shoots should be forced into the ground as deep as possible. Cuttings require more time to sprout in the spring than the neighboring older stools which already have fully developed root systems, and in order to prevent the shoots of new cuttings from being over-topped and choked out, long rods are planted. Rods used in restocking open places must be free from branches so that they are not swayed and twisted too much by the wind, which would interfere with their root development. PROPER ROTATION FOR BASKET WILLOWS. After a number of years the rods show a diminished height growth even in the best regulated holts. This is the first sign of the deterioration of the stools, or of an insufficient supply of soil mois- ture. It is often a waste of time and labor to attempt to revive an old holt after it has shown marked signs of diminished yield. A young holt gives better returns and it pays to grub up the old stool early and seed the area to wheat, corn, or potatoes. After several years the area may again be planted to willows. Proper rotation should not only be practiced with the ordinary farm crop, but also with the different varieties of willows. The Welsh may be followed by the American green. The most experienced willow growers in Europe find it most profitable to rotate the crop every 12 or 15 years, depending upon the soil and variety of willow. CUTTING THE RODS. The rods may be cut as soon as the wood has fully matured and the leaves have fallen. As a rule, rods are cut in this country during February and March, but they may be harvested any time between the end of October and the middle of March. If cut after the sap rises, the stools suffer from loss of sap and the shoots themselves become less valua'ble. Rods intended to be dried with the bark on should be harvested during December and January. It is very essential to cut the rods close to the stool. This will aid a great deal in keeping the stools low. A very objectionable fea- ture in a poorly managed willow holt consists in high stools. As a rule, stools heave considerably in rather moist soil, and where careless cutting" is practiced they are apt to become especially high. It is best to use a short-bladed knife, shaped somewhat like a sickle, which should be kept very sharp. The cutting stroke must be clean and decisive. Each rod should be held tightly in the left hand and cut by a single stroke. 13 I-KIXINC I' I II". RODS. A certain percentage of the roils of all varieties of basket willow.s and under all methods of management develo]) side branches. If the grower does not care to separate the l)ranched from the un- branched rods, pruning is most conveniently done just before cutting them. A very sharp, sickle-shaped knife is used for this ])urpose. Care should be taken to shave off the branches as close to the rod as possible. It is often advisable, however, to separate the branched from the unbranched rods, and when this is done considerable is gained by pruning after cutting, since it is nuich (juicker and easier to sort the branched from the unl)ranche(l rods l)efore than after pruning. SORTING THE RODS. The rods are sorted in four height classes immediately after cut- ting. This is commonly known as drafting and consists in sorting the rods according to sizes by means of a measuring stick placed upright on the side of a barrel in which rods are stood on end. They are then removed according to their height, the tallest first. When the rods are intended for peeling they must be tied firmly in bundles of convenient size and weight (about 40 pounds) and placed standing on their butts in water to the depth of 4 or 6 inches. These bundles must be firmly fixed in position so as not to be dis- turbed by the wind. In this shallow pond, which is commonly called a pit, a rack must be arranged to keep the bundles upright and secure. The rods must remain in this position until the sap rises and they begin to sprout. They are then ready to be peeled. If they are to be used green or with the bark on, they must be set up thinly and loosely on the butts in any dry place until the sap has left them. As soon as they dry they must be put under cover, pre- ferably in a place where the moisture is uniform. Tbey may be sort- ed either before or after they are dry, but they should not be tied into bundles until they are thoroug'hly dried and carefully sorted. Tie the bundles firmly and securely. In cases where the rods are long, it is advisable to sort them into 5 grades, and great care should be exercised to have the rods in each bundle as nearly uniform in length as possible. PEELING THE RODS. Two methods are employed in the preparation of rod's for peeling, both quite simple. In one case the rods are placed in a pit contain- ing 4 or 6 inches of water as above described and left there until the 14 sap is up and the bark can be easily removed. This is known as sap peeHng". The other me'thod, commonly referred to as steam peeling, consists in steaming or .boiling the rods imtil the bark is loose and readily comes off. In the ordinary method of sap peeling, the rods remain almost pure white. The apparatus for peeling consists of a round steel rod from ^ to 5^ of an inch in diameter and about 4 feet long, which is doubled over so that the two ends are brought together making a double rod 2 feet long. This instrument is known as a brake, and there are a great many different designs. The lower or welded end of the parallel rods must be inserted in a log placed at a convenient height. The brake must be perpendicular and have the upper ends of the prongs sl'ightly curved out one inch from the top so that the rods can easily be put in the brake. The operator places the thick end of the rod between the prongs of the brake and draws it to- wards him and the bark is at once separated from the wood. The small end is then treated in a simikr way which completes the peel- ing. The white peeled rods should be bleached quickly in the sun and thoroughly dried in the open air, after which they s'hould be stored in a dry, dark place. When thoroughly dry, they must be tied in t'undles about 3 or 4 feet in circumference at the base, three bands to each bundle, one near each end and the third in the middle. The rods in the bundle must all be as nearly parallel as possible. It is a good plan to place a small armfull of rods in the middle of the bun- dle, so that the ends extend out about one foot beyond the bottom and tie it in this state. By lifting the bundle a few times, and letting it fall on its base on the iground, the protruding butts act as wedge and tighten the bundle. Rods peeled by using boiling water or steam ,are known as buff in dis'tinction from white rods peeled in the ordinary way. In the process of bdiling, the coloring matter or tannin in the bark stains the willow a buff color. White rods are used almost exclusively for high grade wicker work, but it is often claimed that steam-peeled rods are the .more durable. Andther method of preparing the rods for sap peeling is coming into use. They are cut and sorted in the usual way and placed in a steam-heated room having a temperature as nearly as possible at summer heat. The bundles are stood upright on a dirt floor of thor- oughly saturated clayey loam. This serves the same purpose as a pit for storing rods preparatory for sap peeling in the spring. When 15 rods arc thus treated after tiie first h'ich the grower must learn by experience. One must familiarize himself with the require- ments of the willo\vs he wishes to plant and with the soil and mois- ture conditions of the holt. In order to avoid a great many mistakes, it is especially advis'able that willow groovers in a .community form an association, and hold meetings at convenient places, wihere their experiences may be communicated to others and thus be mutually l">enefited.
