My issue on my ayers pears this year is after blooming we had some cold weather maybe 28 so i thought they were safe as apples next to are loaded but now i see the old blossoms are dead and black? I have not been to farm since they had bloomed so was expecting a loaded tree , i dont see any fruit, i do see a couple small limbs that looks like some fireblight but very minor also 2 kiefer pears close by that had blooms and also no fruit but no fireblighht looking signs, 2 years ago the ayers were loaded of course none last year. Kiefers bloomed a little after ayers and my other pears are not old enough yet so also wondering about pollination issues we have had very cool spring. thanks for any input sorry for long winded post.
