RENOVATING OLD ORCHARDS 



tree is l)oniid to make a still more rank growth and it is going 

 to be practically impossible to check it in the autumn in time 

 for it to ripen its wood before winter comes on. The result 

 is almost certain to be more or less damage to the cambium 

 layer and consequent killing of the adjoining bark. If the 

 damage is "less" we are likely to find injury around the trunk 

 of tlie tree, as is shown in Figure 103. In this case the bark was 

 killed only part way around and the tree survived, but it is like a 

 man with one lung so far as getting down to work is concerned. 



Fig. 104. — An orchard damaged by too much nitrogen. The trees have grown late in the 

 autumn and have not been able to withstand the cold. 



When the damage is more severe the tree may be killed outright 

 or so severely damaged that it is practically out of the race. 



Figure 104 shows a case of this kind. It was in an orchard 

 in the Annapolis Valley, Nova Scotia. The trees had been 

 rather neglected for several years, being kept in sod and no 

 fertilizer used. Then the owner had a ''change of heart" and

 not very fertile, and the past neglect had made it less so, with the 

 result that the trees had made long, straggling roots in search 

 of moisture and plant food, as it is well known that trees will
