 Fig. 474. —A large, thick-rinded, lemon-like fr., some- 

 what cult, in Flor. and Calif. The rind is used in the 

 making of preserves and confections. 



The Citron is propagated by cuttings, layers, budding, 

 and grafting. The usual method of propagating is by 

 budding on a vigorous stock, in Florida preferably the

 but also on the sour orange. Grafting is so uncertain, 

 owing to the prevailing high temperature, that it is sel- 

 dom attempted. Cuttings of ripe wood root readily, 

 both m the open ground and the propagating house. 

 For open ground, select wood thoroughly ripe in De- 

 cember and cut in lengths about 6 to 10 inches ; clip 

 off all but the top leaf, and insert in rows in well-drained 

 soil leaving the top bud exposed to the air. Watering 

 must he thoroughly kept up until the succeeding rainy

 feet apait (although this is not arbitrary), as sufficient 

 room should be allowed for cultivation, hauling ferti- 

 lizer and fiuit, and plenty of sunlight and air. An 

 abundance of sunshine and breezes are the greatest aids

 and fruit githering difficult. Cultivation is essentially 

 the same as for the orange and lemon: shallow plowing 

 in December at the time of applying fertilizer, followed 

 by thorough harrowing every two or three weeks until 

 the latter part of June. This keeps the top soil loose, 

 conserving the moisture, and keeping down weeds and 

 glass during the dry season. After the rains set in
