No fruit on my pear tree

​Question:  I’ve had a pear tree for at least 10 years, and it gets a lot of flowers and green leaves, but I don't get any fruit off of it. What can I do?

NICK: What I really need to know is whether or not you had any fruit on the pear tree in the previous 10 years, because one of two different things is happening. Either you're pruning it incorrectly, or number two, which is probably most likely the reason here, it's not getting enough or it's getting too many chill hours, which is a collective amount of hours that the tree will hold in its system and then when it gets enough, it'll be able to produce for you. Certain trees need a lot of chill hours, or others they need very little, and that's usually around the 45-degree mark.
