I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
It is difficult to say how much water a plant needs daily since soil type, sun exposure, temperature, etc. will all affect this. I would build a raised berm of soil about 3 - 4 feet in diameter around the base of the tree and fill it with water every 2 or 3 days depending on how hot and sunny it is. Choose the best of the two current trunks and cut the other one off at the "V". Leave the lower branches until next Jan or Feb and remove them up to about waist high then. Wait until a year later to remove them any higher.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
