166 THE NURSERY. 



may produce twenty-five to fifty, and even one hundred 

 in one season. Plants to be propagated from should have 

 abundance of space, and a deep, rich soil. An applica- 

 tion of liquid manure will stimulate their vigor, and in- 

 crease the number and strength of the runners. 



The Bush Alpine varieties, which make no runners, are 

 usually propagated by division ; but it is much better to 

 propagate them by seeds, which should be sown as soon 

 as the fruit is ripe. 



5th. Raspberries. The usual mode of propagating the 

 Raspberry is from the shoots, or canes, called " suckers," 

 which are produced from the collar and spreading roots 

 of the plant. A crop of these spring up every year. 



Much better plants, and many more of them, may be 

 produced by taking up the roots, cutting them into small 

 pieces, say an inch long, and planting them in beds of 

 good, rich, light soil, with a little bottom heat, and a 

 glazed sash over them, until they have made a good start. 

 They may then be transplanted to the open borders. In 

 this way fine plants are made in one season much better 

 than the ordinary suckers from old plants. 



The American Black Cap family of raspberries are 

 propagated from the tips of the shoots, which are fastened 

 to the ground. This is their natural method of multiply- 

 ing themselves. 



The seeds are washed out of the ripe fruit and sowed 

 at once, making good plants the next season. 



6th. Blackberries. The Blackberry is propagated in ex- 

 actly the same way as the raspberry, but the cuttings of 

 roots make much more desirable plants than the suckers. 

 Indeed, the latter are seldom fit to be planted ; being 

 destitute of fibres, they mostly fail. 



7th. Mulberries. The principal Mulberries grown for 

 the fruit are the Black Mulberry (Morus nigrd), and Down- 

 ing's Everbearing, a seedling of the Morus multicaulis, 

 used so extensively in China to feed the silk-worm.
