Do you like to stake your trees at planting? Some say it's good and some say it's not so good. Many trees even come already staked in their pot. I don't know what the case was here but . . . . . . . these ties and stakes should have been removed long ago. This is one of three Jatropha integerrima that were planted 10 or 11 months ago. You can see the damage done by the ties.
And that's nothing compared to the damage done by being tied so close to the stake for months and months and months. I'm not saying don't stake - just be sure to check your staked trees on a regular basis!
