SHADE TREES AND SHRUBS 



717 



Work of the Hickory Bark Borer 



sections cut from damaged trees, showing the holes outside the bark made by the borer and the 



galleries inside the bark 



establishment of municipal nurseries, 

 city forests and state parks and the 

 proper ground cover for slopes and 

 woodlands are questions of the latter 

 class. 



To the one interested in the care of 

 trees there may thus be offered hundreds 

 of suggestions of innumerable practical 

 value. The men at present engaged in 



this work are still learning and exchange 

 of experiences and discussions would 

 therefore be of value to all. This is 

 just what this department aims at. 

 It will need the cooperation of all 

 interested, welcoming both your ques- 

 tions as well as your findings and it in 

 turn will aim to make its information as 

 authoritative as it possibly can make it. 



ADVICE FOR THE MONTH OF JUNE 



Cultivate and water all young plants. It is quite essential that young plants, 

 especially those recently set out should be watered and weeded during the summer 

 months. No fixed amount of water can be prescribed; that will vary with the 

 size and habits of the plant as well as with the local soil and climatic conditions. 

 It is well to dig down occasionally and examine the moisture conditions of the 

 soil around the roots, this will avoid the danger of overwatering. 



Destroy the nests of the forest tent caterpillars so common at this time on 

 wild cherries, mulberries, willows and other trees. Apply a burning rag or torch 

 to the web or else squirt a little kerosene into the web. Where the webs can be 

 readily reached, the latter is preferable because it prevents burning of the infested 

 branch .
