Thanks a lot guys for Welcoming me and for your replies.
The tree is now two and a half years in the ground and it's around 12 feet tall. I currently don't water it - it gets its water from rainfall at this point (we had a wet last weekend.) However, there are other plants (not under the drip line) close to the tree that get more supplemental water such as Heliconias and Alocasias.
I don't have a picture of the tree at this moment since I'm not home, but I'll take some pics tomorrow morning.
Thanks a lot!
