^\' inter grafting with dormant wood makes good pot 

 ])lants of hybrid perpetual varieties. Rosa rubiguiosa 

 (sweet briar), R. icatsoniana, and several other species 

 are used to some extent. Usually the shield method of 

 l)udding, Ijut sometimes veneer grafting, is employed. 



267. Hytrid stocks for roses. — A writer in Aiiiericau Gardening 

 considers Manetti stocks (popularly used) unsuited to American 

 climatic conditions. Where perfect hardiness is 'required he has 

 found Rosa sctujera, R. ll'icliuraiana and R. nibiginosa superior: 

 for, he says, "all make good, deep roots, and are little affected by 

 dry weather when established, and are not at all disposed to 

 sucker.'' The best of all stocks he considers to be a cross between 

 Clothilde Soupert and Crimson Rambler, both varieties of R. Multi- 

 flora. These stocks are exceptionally vigorous, do not sprout, and 

 are easily budded and in hardiness little inferior to the native species. 

 The roots are easily splice-grafted, but the stems are not so satis- 

 factory for grafting. For tree rose effects he prefers to bud high 

 on strong sweet briar shoots and trim off all other shoots as soon 

 as the bud has formed a fair top. 



268. Grafted roses for forcing.— A. B. Scott has grown half 

 a dozen varieties of forcing roses on their own roots and on 

 manetti stocks. Since all but .American Beauty and Perle des 

 Jardins did much better as grafts, he concludes that grafted roses 

 •make strong, vigorous plants much quicker than roses on their 

 own roots, produce as many, if not more flowers, of which a larger 

 proportion are e.xtra fine, and the plants are said to have more 

 vitality. Manetti is considered best for stocks. 



269. Citrus propagation. — Each principal citrus section 

 and soil has its preference of stocks. In the. heavy, moist 

 fertile soil of Louisiana and Mississippi, Citrus trifoliata. 

 a deciduous species, leads becau.se of its vigor and 

 hardiness, which are imparted to the cioti because it 

 becomes dormant in fall. In northeastern Florida tri- 

 foliata also leads, though some of the more lusty-grow- 

 ing stocks give good results in deep sandy lands. In cen- 

 tral Florida, on sandv soil, rich in vegetable matter, 

 ]3omelo stock does best, though the sour orange gives a 

 hardier tree. In South Florida rough lemon is far in the 

 lead. It is a rampant grower which does well on soils 

 almost sterile for other stocks. The fruit it grows from 

 cions worked on it is like!}- to be coarse. On heavy soils 

 free from limestone, pi.imelo and sour orange do well.
