my pear tree does not produce pears every year. Is that normal and, if not, how do i fix it?

Question

We have deer that go through the yard, but there are no pears at the top of the tree either.

Answer 1

Pears require a number of hours of chill time. Is it possible you had a mild winter on the off years? Also, too much fertilizer will result in lots of foliage but no pears. You don't mention any signs of disease or insects, so it may be something environmental. Lack of pollination is also possible. Here is more information:
