Border Fence-Trees or Fence?

Hi,
I am having 3 acres of land - we grow banana and turmeric as major crops. Planning to put border fencing.

Can anyone suggest what kind of trees like Teak, Coconut, Sandal wood etc. good for fencing? Is it advisable to put trees as borders?

If its not advisable then I can plan for cement block and iron Fencing.

THanks,

You can have even Jackfruit as border crop for extra income.

Thank you padmanabhan_ganesan…

Dear Mahesh1g,
If you do not want to spend lot of money, you can plant the Caesalpinia crista - Gajga ( Hindi & Urdu ). I am giving here link from agriculture.com. you can buy the seeds it will give a very nice protection from all animals. below is the link
