Dropped fruit on pear tree
My pear tree was loaded with pears and by mid June all the fruit has fallen off. What happened, is there something we can do to guarantee fruit sets?

What type of pear is it? do you have more than one type of pear for cross pollination? Bartlett pears will set a partial crop with a warm bloom.
The most likely recommendation is that you had poor pollination and the tree shed a lot of seedless fruit. Was it rainy during bloom? Pear flowers are not that attractive to bees and other blooming plants can distract them. It is also possible that the tree was stressed soon after bloom and shed fruit. Were the trees sprayed with anything? Commercial pear growers actually spray with chemicals to reduce the crop and insure good fruit size for the remaining fruit. I would not suggest fertilizing the trees to increase the crop as that will only increase shoot growth and make the trees more susceptible to fire blight.
