Remarks 



In 1888 a ten-acre grove 



of hardy catalpa was 



planted at Pioneer, Iowa. 

 In 1908 the grove eon 

 sisted of trees 25-32 ft. 



tall, 4-10 in, diameter, 



worth (2,825.70 in posts. 



Catalpa plantations 



should be protected by a 



windbreak of hardier 

 trees. 



The common catalpa 

 is much less hardy, and 

 less erect in habit. 



Fragrance of wood uti- 

 lized as insecticide. 



The western red cedar 

 < J. scapular um) and the 

 southern red cedar (J. 

 barbadeiisis) give wood 



of similar grade.

Not shade-enduring, 

 therefore pure forest 



recommended, or associ- 

 ates like Russian mul- 

 berry or Osage orange 

 which will endure shade 

 and so act as a "filler" 

 to force pruning ami 

 straight growth of the 

 catalpa. 



Plant pure, or with 

 Osage orange or honey 

 locust for windbreaks. 



( irowth 



1 lb. seed yields 12.0011 

 seedlings. Transplant 

 from nursery when they 

 are 1 yr. old (12-14 in. 

 high |, Space 4 tt. each 

 way. 



Growth most rapid. 

 Annual height increase 

 2J ft., diam. increase \ 

 in. Post size may be 

 reached in 8-10 yrs. 

 Telegrapli poles in 20-30 

 yrs. 



If entire seed forest 

 cut for posts after 1.5-20 

 yrs., it will renew rapidly 

 from stump .sprouts. 



Buy nursery-grown 

 seedlings, or transplant 

 wild seedlings to nursery

Recommended for eco- 

 nomic planting on fertile 

 lands of the Middle West, 

 south of the 41st parallel. 

 It grows well in the south- 

 ern parts of Ohio. Illinois 

 and Indiana: in Nebraska 

 south of the Platte River; 

 in eastern Kansas; and 

 on irrigated lands in New- 

 Mexico, Colorado and 

 Utah. Will not grow- 

 well on poor sandy or stiff 

 clay soils. 



Thrives as far north as 

 N<>\ a Scot la and Dakota, 



but reaches best develop- 

 ment south of Ohio

Recommended for eco- 

 nomic- planting especially 



in Plains Slates west of 



Mississippi. 



Economic Value 



Wood most valuable; 

 light . elastic, very durable 

 in contact with soil. 

 Fence posts may remain 

 sound thirty to forty 

 years. Used in cabinet 

 work. Has high value 

 for fuel, posts, small poles 

 and railway ties.
