STOCK AND CION HANDLING 2OJ 



Winter grafting with dormant wood makes good pot 

 plants of hybrid perpetual varieties. Rosa rubiginosa 

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

 are used to some extent. Usually the shield method of 

 budding, but sometimes veneer grafting, is employed. 



267. Hybrid stocks for roses. A writer in American Gardening 

 considers Manetti stocks (popularly used) unsuited to American 

 climatic conditions. Where perfect hardiness is required he has 

 found Rosa se'tigera, R. Wichuraiana and R. rubiginosa 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 extra 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 because of its vigor and 

 hardiness, which are imparted to the cion 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 sandy soil, rich in vegetable matter, 

 pomelo 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 likely to be coarse. On heavy soils 

 free from limestone, pomelo and sour orange do well,
