States. The trees were planted to grow posts, telephone poles and 

 crossties. In Indiana there is one plantation 42 years old, but the 

 majority are only 10 to 15 j'ears old. The tree has been planted Ion"- 

 enough in our area to definitely conclude that it should not be planted 

 in any part of Indiana for economic purposes. The range of the catalpa 

 sphinx which defoliates the tree is rapidly increasing, and now ranges as 

 far north as Wells County. In the southern part of the State the trees 

 are usually defoliated twice each year by the larvae of this insect, and as 

 a consecjuence the trees make very little growth, and some owners of 

 plantations have abandoned them on this accoimt. A new insect is 

 appearing which kills the young shoots, which will interfere with the 

 upright habit of the tree. The catalpa is not recommended for forest 

 planting in Indiana, and its use for this purpose has practically ceased. 



The cataljia prefers a moist, deep, ricdi soil, but will grow in almost 

 all kinds of situations. In the northern part of the State, the young 

 trees are frequently winter killed. The tree is cjuite tenacious of life 

 and when cut off at the ground, usually sends up several coppice shoots. 



This species can be recommended for planting for shade for hog lots, 

 and as a specimen tree in parks, etc. It is not a desirable street tree.
