88 SUCCESSFUL TRUIT CULTURE 



but when a crop of fruit is set, unless the fruit is 

 thinned severely, a liberal supply must be used to carry 

 the crop through and not weaken the trees. The best 

 fertilizers to use are those rich in potash and phos- 

 phoric acid, with only nitrogen enough to make a 

 moderately vigorous growth of wood. These materials 

 may be put on in any forms that are most available, 

 but the quantity must be determined by the grower, 

 who alone knows the condition of his soil and trees, 

 and upon his good judgment will depend his success. 



VARIETIES 



The number of varieties of peaches has become so 

 large that the beginner finds much difficulty in deciding 

 what kinds to plant, and yet when we come to investi- 

 gate we find that there are but a comparatively small 

 number of varieties planted by the successful peach 

 growers. The following named varieties are among the 

 best and most largely grown : 



White Fleshed — Of the very early varieties of this 

 group, including the Alexander, Early Eivers, Sneed 

 types, none will be found profitable, as they are certain 

 to be attacked by the brown rot nine years out of ten. 

 Those generally found profitable of this group are 

 Mountain Eose, Carman, Champion and Oldmixon. 



Yellow Fleshed — Triumph (in a dry season may 

 be of some value), Crawford's Early, Crawford's Late, 

 Elberta and Crosby in Northern localities. This list 

 is purposely made very small for the reason that few 

 varieties will do equally well in distant localities and 

 the grower must study the varieties in his own locality 

 and plant such as have proved the most valuable. The 

 experiment stations are all making comparative tests 

 of the leading varieties that succeed in the different 

 parts of the country and can give the best possible 

 advice as to what will be most profitable.
