ily if laid on sand. It is customary to allow these cuttings to 

 dry several days before planting them. See also Cactus.

Seeds, sown where the plants are to stand. 



Orange (Citrtts Aurantiuni). Rutacecc. 



Orange stocks are grown from seeds, which should be 

 cleaned and stratified in sand or other material, until sow- 

 ing time. The seeds should not be allowed to become hard 

 and dry. Some prefer to let the seeds sprout in the sand 

 and then sow them in the nursery, but they must be carefully 

 handled. The seeds are usually sown in seed beds, after the 

 manner of apple seeds, and the seedlings are transplanted 

 the next fall or spring into nursery rows. Care must al- 

 ways be exercised in handling orange plants, as they are 

 often impatient of transplanting. Oranges grow readily from 

 cuttings, although cuttage is not often practiced. Green cut- 

 tings, handled under a frame, give good results. Mature 

 wood, either one or two years old, can be treated after the 

 manner of long grape cuttings. They must have an abund- 

 ance of moisture. Layers are sometimes made. 



The named varieties are shield-budded upon other stocks. 

 Grafting can be practiced, but it is often unsatisfactory. 

 The nursery stocks are commonly budded in the spring, after 

 having grown in the rows one year, which is two years from 

 the sowing of the seed. If thorn-bearing varieties are to be 

 propagated, a thorn with a bud in its axil is often cut with 

 the bud, to serve as a handle in place of the leaf stalk, which 

 is used in summer budding. Many stocks are used for the 

 orange. The leading ones are sweet or common orange, sour 

 orange (Citrtis Aurantium, var. Bigaradia}, pomelo (var. po- 

 melanaor decumana}, Otaheite orange, trifoliate orange (Cit- 

 rus trifoliata), and various lemons, as the "French " or Flor- 

 ida Rough and the Chinese. For general purposes, the sweet 

 and sour orange stocks are probably the best. The sour 

 stock is obtained from wild seeds, this variety having exten- 

 sively run wild in Florida from early times. The trifoliate 

 and Otaheite stocks are used for dwarfing or for small grow- 

 ing sorts, as many of the Japanese varieties. The trifoliate 

 orange is also one of the hardiest of the orange stocks, and 

 its use will probably increase upon the northern limit of the 

 orange belt. Old orange trees can be top-budded with ease. 

 It is advisable to cut them back a year before the operation 

 is performed, in order to secure young shoots. In ordinary 

 greenhouse practice, the seedlings of the pomelo make
