I have a pear tree that is about 4 years old and is not yet bearing fruit. The trunk, branches and leaves are very healthy. At the base of the tree, there are sprouts appearing. Should I trim or cut them off? The sprouts are actually growing out of the trunk of the tree. Thanks, I appreciate your help.
pear trees do not like fertilizer. if you are fertilizing stop and heavily water to leach away the fertilizer
Do you have just one pear tree?
You will need more than one tree of a different variety in order to have proper pollination.
Also your trees may not bear fruit for the first five years, depending on the variety.
I would trim away the little branch sprouts that you are seeing at the base of the tree.
Here are a few links that may help you pinpoint the issue.
