 THE PLANTING OF STREET TREES. 



At first thought it might seem that street trees would need no more careful 

 planting than any other tree, but if we consider how much more artificial are the 

 conditions under which it must live, we can see why special care should be paid 

 to this feature. Here of course is the stumbling block for many ambitious 

 enterprises. And that is, the expense of adequate preparation. 



From actual practice it has been found that for best success a hole, at 

 least three feet in length for each of the three dimensions, should be excavated. 

 If the nature of the soil does not demand an addition of fertilizer, the top soil 

 is put at the bottom and the lower soil was brought to the top. In most cases it 

 will pay best in the end to add some fertilizer. *n some cities the street 

 sweepings are saved and used for this purpose. These are quite excellent for 

 lightening the consistency of the soil but vary considerably in their value from 

 the food standpoint. Again, if the soil is of a very clayey nature, the addition 

 of lime is a valuable point to remember. Fig. represents the method of 

 work in a very good soil naturally approaching the ideal. Fig. represents 

 the method employed by a local stock company of citizens, which cares for their 

 plantings, in Garvanza. This method is to be recommended over the proceeding in 

 any case. In cases of specially clayey soil this company adopts the following 

 method of using lime to free the soil particles. Fig. 



It has been found that by the time the roots of the tree reach the lov/er 

 levels ( ) that the lime has spent itself and broken up the colloidal 

 clay so that the soil is easily penetrated by the roots. 



At all plantings, arrangement is made for watering. Fig. Usually 

 the top six inches of soil is kept loose so that it can be drawn back to form a 

 rim and the hollow flooded. After the water has disappeared this loose material 

 is thrown back as a mulch. For planting on hillsides the tree is pieced as 

 in Fig.
