HEDGES. Living green fences are used for two dis- 

 tinct purposes — defense and ornament. Ornamental 

 Hedges may be rendered defensive by stretching tightly 

 2 or 3 strands of barbed wire through the center of the 

 Hedge. So far, no plant has yet been tested that meets 

 all the requirements of the farmer for a truly impass- 

 able barrier, although the Osage orange {Maehira au- 

 ranliaca) possesses more recommenil:ible feutui-L-s than 

 any other hardy tree. This tree. Imwri ,r, is imi h uily 

 in the northernmost states. Next t.i 1 1 , i .inks

warm admirers and advocates. The h i . i mh mm] I ; n upe 

 (Crataegus Oxiiaeaiitha) may not be planti.-d in this 

 country with any chance of success, owing to fungous 

 enemies, and all of the large-sized thorny shrubs fail in 

 important characters. A perfect thorn Hedge requires 

 unremitting care, and must conform to an established 

 rule, the most important being entire freedom from 

 weeds and a systematic pruning. The preparation of 

 the soil for a Hedge consists in thoroughly plowing and 

 cultivating an area 6 feet wide ami the length the Hedge 

 is proposed to extend. If this space should be fertilized 

 and cropped the year previous to planting, vegetation 

 will be greatly accelerated. The plants must be short- 

 ened, both top and root, and set 9 inches apart in a 

 single row. The double row, as formerly advised by 

 some growers, is now practically obsolete, and justly 

 so, being difficult to cultivate and preserve free from 

 weeds. A trench or furrow is opened through the center 

 of the cultivated strip of a sufficient depth to admit the 

 roots without bemliug In setting, the soil must be 

 made Arm with the aid of a raniiiier, a practice unex- 

 celled for aiding growth, and. indei-d. preseiving plant- 

 life after removal. Pruning is simply an annual neces- 

 sity from the first, excepting when the Hedge is in- 

 tended to be plashed, and even in such cases, after the 

 laying process, pruning must never be omitted during 

 summer. This work is greatly accelerated and conse- 

 quently cheapened by shearing when the plants are 

 young and tender, say during the month of July. As to 

 the best outline, a plain triangle, or what may be more 

 sightly, the curvilinear or Gothic arch, is desirable, and 

 a flat top is to be discouraged, as a body of snow lodged 

 on the latter invariably injures the symmetry and beauty 

 of any Hedge. The ornamental Heilgo proper may be 

 either evergreen or deciduous, and vet in the so-called 

 California privet (Lianstrum onilifoUiiM) are united, 

 to a certain extent, both conditions. Taking into con- 

 sideration its almost faultless character for the purpose, 

 we may assign it a promiflent position at the head of the 

 list. 



Among strictly evergreen plants, the Norway spruce 

 (Picea excelsa) succeeds most satisfactorily. Foracora- 

 bination of cheapness and general titility, the American 

 arborvitae (Tliiija occidentalis) may be placed next, 

 although for decided beauty nothing can supplant the 

 common hemlock (Tsiif/a Canadensis). The number of 

 available deciduous trees and shrubs suitable for Hedg- 

 ing is so extensive that to specify even a few is unnec- 

 essary. Flowering shrubs may, however, claim prefer- 

 ence, and such attractive species as Cijdonia Japonica, 

 Deutzia scabra, some of the spireas, viburnums, etc., 

 may be employed with good effect. Species of Berberis 

 are occasionally used with marked success, especially 

 the purple-leaved variety, although rather formal in 

 character. The most serious annoyance to the Hedge 

 grower is the presence of unwelcome woody vines, such 

 as poison ivy (Ifhus Toxicodendron), Japan evergreen

Hedychiums are strong-growing plants, very orna- 

 mental, both in foliage and in flower. They are essen- 

 tially fall bloomers, although they may be made to 

 bloom more or less continuously under glass. After 

 blooming, gradually dry off the rhizomes, and let them 

 rest for a time. Pot them up in spring or early sum- 

 mer, and give them rich soil and ph-nty of water and 

 an occasional supply of liquid manure. The rhizomes 

 may be divided every two or three years. They need 

 an abundance of water. In fact, the pots may be set 

 half their depth in water, and R. coronarium is often 

 immersed until only the crown is emersed. The com- 

 mon white-flowered species is II. coronarium. This re- 

 quires warmhouse treatment for best results, although 

 it often flowers well when plunged in a warm, half- 

 shady place in the open. The species do not stand frost, 

 but they may be left out in the South if well protected. 

 The flowers are very fraerant; in fact, their odor may 

 be too heavy for a small room.
