plants, wliioli are frequently transplanted or renewed from 

 seed. 



Suckers from old Pear, Cherry, Plum, and other kinds 

 of fruit trees may, under some circumstancss, be worth 

 preserving, especially when other means of propagation 

 are not at hand ; but trees raised from these suckers are 

 seldom as vigorous, productive and healthy as those prop- 

 agated by other and more scientific methods. The same 

 is true of many kinds of forest trees which sucker more 

 or less freely ; and while there may be no difficulty in 

 transplanting the suckers and making them grow, they 

 are, as a rule, inferior to seedlings. 



There are many kinds of herbaceous plants, such as 

 Japan Anemones, the Pachysandras, Lilies-of-the- Valley, 

 and some of the herbaceous Spiraeas, that are usually 

 propagated by suckers, but they are so frequently trans- 

 planted and divided that no apparent deterioration has 

 as yet been observed from this long continued mode of 

 propagation. 



PEOPAGATioiir BT DIVISION. — In propagating plants 

 by divisions, we take advantage of all the various forms 

 of growth wherein buds or sprouts appear on the crowns, 

 side shoots, or the base, of the stems. With many kinds 

 of herbaceous plants, division of the clumps of the buds, 

 stems and roots is the most common mode of propagation. 

 There are also various kinds of ligneous plants which 

 may be rapidly multiplied by divisions, employing for 

 this purpose the sprouts which spring up from the base 

 of their stems. The number of these sprouts may be 

 greatly increased by severely heading-back the main stems 

 early in spring, thereby forcing the stump to produce a 

 large number, and permitting the entire forces of the 

 roots to be expended in producing buds and sprouts. 

 After these sprouts have reached a moderate size they 

 may be banked up and their bases covered with soil, to 

 induce the formation of roots at this point, as described
