ACKNOWLEDGMENTS 
it is surprising how few books or articles are available for 
j( reference and study on the propagation and cultivation of 
native , or foreign, plants in the Southwest. Recognizing this 
IP fact, a questionnaire was sent to a large number of Garden 
Hr Club members, and other experienced gardeners, who, by liv¬ 
ing with and learning the needs of their plants, were peculiarly 
qualified to share their knowledge. Because of the quantity of 
material received thru their generous response, it was found impos¬ 
sible to note and give credit for each specific bit of information, 
yet all have been incorporated into the composite whole. Each 
chapter contains a contribution from an experienced grower to¬ 
gether with some additional notes by the Editors. 
Special thanks are extended Hon. Hatton Sumner for enlisting 
the co-operation of the United States Department of Agriculture, 
from whom was received a quantity of valuable scientific data.
