Olive Trees

Our large, mature olive tree didn’t fruit this year after pruning. Why?

We had to remove a large central limb on our old (50+? years) olive tree because it was finally rubbing against the main electrical wire to our home. It had had minimal pruning in the last 45 years. It had always produced olives - some years more than others. It was pruned in Oct. or Nov. here in inland Northern Calif. It appeared not to fruit at all this year, but close examination now (late Aug.) reveals about a half doz. olives. Can we expect that the tree will have "recovered" from the insult of last fall's pruning in time to fruit next year? Is there anything we can do to promote a return to fruitfulness? Thank you!

The pruning cut may not be the reason for the lack of fruit. Weather and environment may have played a factor. Due to the age of the tree, it may need rejuvenation. Also olives tend to fruit lightly one year and more heavily the next. So your tree may just be experiencing one of its off years.
