242 THE NURSERY LIST. 



able plant in one year after transplanting from the stools, 

 but Smith Improved may require a year more. Layered 

 plants are usually set in nursery rows for a year after 

 removal from the stools. Green-layering during summer 

 is sometimes practiced for new or rare varieties. Strong 

 plants may also be procured by tip-layering, as in the 

 black raspberry (see page 36). If it is desired to train 

 the weaker gooseberries in tree form, they may be grafted 

 upon the stronger-growing varieties. 



Gordonia. Temstramiacea* 



Propagated by seeds or layers. 



Gorse. See Ulex. 



Goumi. See Elaeagnus. 



Gourds ( Gucurbita Pepo, Lagenaria, etc.). Cucurbitacece. 

 Seeds, after the weather is settled and ground is warm. 



Granadilla ( Passiflora edulis, etc. ) Passifloracetz. 

 Propagated by seeds, or, less easily, by cuttings. 



Grape ( Vitis, several species). Vitacea. 



Grape seedlings are very easily grown. If the ground 

 is fit and there is no danger from vermin, the seeds may 

 be sown in the fall, but they are usually stratified and 

 sown in spring. They come readily if sown outdoors, but 

 some prefer to force them under glass with a mild bottom 

 heat. Seedlings do not "come true," and they are there- 

 fore grown only for the purpose of obtaining new sorts. 



The grape is very readily multiplied by layers, either of 

 the ripe or green wood. The ripe wood or canes may be 

 layered either in fall or spring, but spring is usually 

 chose'n. The cane is simply covered up 2 or 3 inches 

 deep, and nearly every bud will produce a plant. In 

 August or September the layer should be lifted and cut up 

 into plants. Better plants are obtained if only the strong- 

 est canes are used and only a part of the buds on each are 

 allowed to grow. The cane is usually cut back to four or 

 five buds, or if very strong plants are desired only one bud 

 is left on each layer. Canes of the previous year, those 

 recently matured, are preferred, although wood two or 

 three years old may be used, but in this case it is usually 

 necessary to cut or otherwise wound the joint in order to 

 induce the formation of roots. Vines or stools grown for 

 the production of layers should be cut back severely in 



fall or winter, to induce a vigorous growth of canes the
