Tall Avocado tree which doesn't bear fruit. What to do?

[NewB_NewB]

Around 1 year ago, we moved to current house which has many palm and fruit trees including a very tall avocdado tree in our backyard. 
However we hadn't seen the avocado tree had fruits on it while other avocado tree had fruits. 
We tried to water regularly, and it got few flowers couple months ago.
However it dropped all flowers suddenly, so it didn't bear any fruits. 
We might missed to water one or two times  , and it might be the reason of dropping flowers, and no fruits. 

Anyhow, after that, we didn't take care the avocado tree, and now it has dropped many leaves. 

I want to try to make the tree to have fruits again. 
Can you give me some idea why it didn't make fruits, and how can I make it to bear fruit. 
I heard from someone that if fruit tree is old, it will not produce fruits like when it was young. Is it true??

By the way, for the size of tree, how often and how much water do I need to water?
And how often, what kind of fetilizer do we have to use?
It is too tall. Can I cut the top trunk to make it short? 
By the way, Can you tell what kind of avocado tree is?

Thank you.

  This is your best resource for everything regarding fertilization, watering, pruning, etc.. Avocado..  W/ out fruit, it will be harder to tell which type though the foliage of both Guatemalan and Mexican types ( especially ) will smell like Anise / Licorice when crushed in hand.  As far as fertilizer, i myself only use organic.. Many options to choose from available.

The way the trunks are growing together, it looks like a seedling. They can take 10 or 15 years to fruit.  Avocado can be severely pruned without harm. I would cut it down to 8 feet and keep it at that height with late summer pruning. Avocado flowers are not the most attractive flowers in a garden. When the flowers open, spray a solution of 2 tablespoons of honey and a quart of warm water in a quart sprayer on the flowers. This will get the bees' attention and get you fruit.

Thank you for the good advice! So it is not a good time to cut the trunk now winter, right?

Winter is a great time to prune, spring is right around the corner and it will go into super bud mode and start growing crazy!  Every winter avos get pruned down to about 2-4’ in commercial operations.  Don’t be scared to cut it, makes harvesting easier...  I’d say 4 is a good height for balance between harvest ease and ground maintenance like mowing or weeding around it.  Use something like 18-6-8 during green growth, then when it gets to be fruiting use something with a higher K ratio.

Oh and mulch it’s root zone heavily, 8” deep easy...  smother the weeds and keep moisture on the roots, then you can forget a watering or three.

By  the way, there is a tall palm tree just 3 feet away from the avocado tree. 

You can see it in the pictures that I attached above. 

My father told me that it might be the reason of not bearing fruits. 

Is it possible?

Hi,

I cut it down to 8-9' yesterday.

And I will spray honey water when it has flowers on it. 

 

By the way, how often and how long do I have to water for my avocado tree? 

I'm going to put mulch around the tree. 

 

Thank you.
