Olive trees drying out and giving no fruits at all.
My name is Huseyin Demir from Turkey/Aydin.
I have 100 hectars of olive trees, oranges, mandarin oranges and prunes. My main issue is with my olive trees, most of them are 15-20 years old and a few around a 100 years old. They do not grow any olives (if they do, its countable) for some reasons and I can't figure out why. I had them pruned last year (cutted all dry branches, etc), regularly watering the whole place (once per 2 weeks).
We used to live in Canada and made a comeback to live in Turkey. We are pretty new to trees maintenance, gardening, etc...
Any advice or anything that would help those trees give olives would be highly appreciated.
Also please take a look at this pics. It's a single olive tree near the entrance of my farm. Its never getting watered and no maintenance at all but its the single and only olive tree in over 300 trees which dont dry out and gives olives. I just don't get it
Thanks in advance for any help
