Question

pear tree that bore no fruit and two plum trees that have little yields ie 8 plums on each tree. They are more than five years old possible as much as 20 years old. How can I encourage them to bear fruit. The trees had pollen in spring and have had plenty leaf growth but poor fruit yields

I would, first, test the soil to make sure that the nutrient content and pH are within range.

Once those are in range, your trees should be producing again, given that they aren't too old for production.
