Not enough information to determine exact problem. Often things like this are centered on the roots, as the roots go so goes the top. Fertilizing only helps when a nutrient deficiency is the issue - and the right fertilizer for that particular deficiency is used, in the right amount.

I have the same symptoms, and some pix are on the link below. (Click on each pic to enlarge it.) My two Cleveland Pears were planted a year ago. This spring, one is full of leaves and flowers, the other has only a few leaves. Both were professionally planted, and I believe were correctly watered last year. I have about two weeks left on a one-year warranty. Any ideas?

I am having the same problem as jimb_2008 only my pear tree is about 7 years old. We had a freeze last year right at the end of the blooming time and the leaves were small and sparse. This year we had a great bloom from the tree but now the leaves are slow to come and sparse again. Any suggestions?

jimb~Get your money back on the slow one, and plant a redbud. It's always a good idea to diversify your plantings anyway.
