I have two Kieffer pears, one very old and one very young, I also have a mature Bartlett pear near by. Last night we got nearly six inches of snow with a low temp of 30 degrees. Tonight we are expecting a low temp of 28 degrees. Do You think my Kieffer pear will produce fruit judging by the stage of the blossom. The Bartlett I have is about a week behind but in blossom and for some reason rarely produces an fruit and I am not sure it is much value for pollination either. Let me know what you think. I have had this Kieffer pear for many years and can't remember a year it did not have any fruit.
