CITRUS TREES AND THEIR DISEASES 27 



Now, this condition worked a hardship upon the 

 body and also the branches of the citrus trees, and 

 especially with trees that were densely thick and with- 

 out air chambers from the north and east so as to let 

 the air come in contact with the body of the tree. Or 

 in other words, the two o'clock sun produces an intense 

 heat in a closed tree from the south and west, which 

 would produce sunburn of the branches and check the 

 flow of sap and finally reach its way down to the body 

 of the tree and will eventually cause scaley bark in 

 the near future on many trees. 



This condition is what led the writer to the dis- 

 covery of his wonderful tree tonic. It is absolutely 

 necessary to make some applications upon the body of 

 your trees at least once a year that will keep the bark 

 in a nice soft velvety condition where it can expand 

 with a natural demand for growth. This also keeps 

 the bark, and sap cells open where the mechanical ac- 

 tion of the tree may be strengthened so that the nutri- 

 tious matter gathered from the soil can be properly 

 distributed to all points of the tree. 



The writer doesn't ask you to purchase his reme- 

 dies, he just simply gives you the facts that are neces- 

 sary to apply some solutions of some kind or changes, 

 especially in Southern California where the distribution 

 of rain fall is so wide apart. 



The body needs moisture and needs a coating of 

 something that will retain and hold moisture during 

 this dry period. You probably can find some solution 

 that would apply and at the same time be a benefit to 

 some extent your tree, but you must understand and
