Water requirements for a new tree.
We planted a 1 1/4" Flame Maple. Could you tell me:
How much water in gallons or how long with a spray nozle?
How often it needs watering?
How many weeks or months do I maintain this routine?
Do I water the entire rootball or just up by the tree stem--it was in a container?
Are root growth stimulants required? How often?
Thank you for your time.

During drought, trees grown in sites without lawn irrigation need 10 gallons of water each week per inch of trunk diameter measured. The trunk diameter measurement should be taken at 6 inches above the soil for a 1 to 4 inch diameter tree. As a rule of thumb, it takes about a year per inch of trunk diameter for a tree to establish and regrow its root system. Water the entire root ball and the surrounding soil. No root stimulants are needed - water is the best root stimulant. Specifics on watering can be found at: http://www.ext.colostate.edu/pubs/garden/07240.html
