WATERING WALL TREES AT THE ROOTS. 



As the result of experience gained in the lifting 

 and transplanting of wall trees, not only of the 

 peach, but also of the apricot, plum, cherry, and 

 pear, I am fully convinced that the soil about the 

 roots of trees planted at the foot of walls having 

 various aspects, but more especially that in which 

 trees are growing against walls having south and 

 west aspects, is invariably too dry, if not uniformly 

 dry, for healthy root and branch growth. This I 

 have found to be the case even in a summer and 

 autumn that might fairly be described as wet. This 

 however, is not to be wondered at, seeing that, in 

 the very nature of things, the bricks and mortar of 

 which the footings of the walls consist are of a 

 most moisture - absorbing nature. In addition to 

 this, both the border and the alley immediately 

 over the roots of the trees are sloping from the 

 wall and the surface hard circumstances which 

 allow any rain falling thereon to run off, and rain 

 coming direct from the south and west run off in 

 the same way. Therefore in these circumstances 

 wall trees, especially peach trees, should receive 

 frequent and copious waterings at the roots during
