Instructions say to prune in the late summer or early fall. But I know it also says to prune before the growing season. Then I notice my trees have been doing a lot of growing lately so I am supposing I am in the growing season.

I have a kieffer pear that is a V and has a small side and a large side. Can I cut the small one off now since I dont want it to grow? Will this hurt the tree?

I also had some suckers/water sprouts at the base of my Asian pear trees as well as the kieffer which I cut off last week. If I cut here and there when I see a branch sprout low or go vertical - is it ok to prune as they come or should I wait until the end of the growing season and do it all at once? And when is growing season officially over?

Also, my small little asian pear trees (one had some fire blight which I cut and disposed of) have some small fruit on them already. Is this odd? I was told they would not fruit for 3 years - I planted them last year.

Sorry all the questions. My Lowes and Home Depot people dont seem to know much about fruit trees at all.
