rooting tree, and cultivation should cease when it would be a dam- 

 age to the root system. 



The catalpa sphinx has appeared in many of the catalpa plant- 

 ings in the southern part of the State and the trees are twice defol- 

 iated each year, and as a consequence the trees make but little 

 growth. 



In forest planting in Indiana where the locust can not be grown 

 successfully it appears that the catalpa is the most suitable tree 

 to plant as a temporary tree between trees that are intended for a 

 permanent stand. 



The last year's growth of the catalpa in our area is frequently 

 winter killed until the tree becomes 4-6 years old. During mild 

 winters the ends only of the shoots may be killed, while during 

 severe winters young trees may be killed back to the ground. In 

 case only the end of the shoots are killed it is advised to wait until 

 the buds begin to swell and then cut it back to a strong bud. If 

 the tree is killed back to, or near the ground, cut it off about an 

 inch above the ground.
