BLOOMING DATES OF PEARS 



POLLINATION OF PEARS

As very few varieties of pears are largely grown in California 

 and as the Bartlett generally bears well when grown in large acreages 

 by itself, the Eastern claim that the Bartlett is self-sterile does not 

 seem to be justified in California experience. Recent observations 

 indicate that even at the east the Bartlett is self-fertile when conditions 

 are favorable to setting of the fruit and self-sterile when they are 

 otherwise. As conditions are usually favorable in California this may 

 be the reason why its self-fertility is more conspicuous here than at 

 the east. It has been individually noted, however, that the White 

 Doyenne is a good fertilizer for the Bartlett. The Winter Nelis is 

 one of the pears commercially worth growing which is most apt to 

 be fruitless, but thus far association with other varieties has not 

 been demonstrated to be a full remedy. For the assistance of those 

 who desire to test pear pollination the following statement is made 

 of the relative dates of bloom of a large number of varieies, based 

 upon records kept in Tulare County :
