Answer: The best thing you can do for your newly planted tree is to water it deeply once each week to help it develop a deep and healthy root system. I'd build a water well or watering basin directly beneath the tree to facilitate watering. Simply mound up a few inches of soil in a circle around the tree, about 12" from the trunk. Fill this basin with water, allow to drain, then fill it a second time. Do this once a week throughout the growing season - until fall or winter rains take over the job for you. Watering this way will concentrate the water over the root system and allow it to trickle down, wetting the entire root mass. Once a week is all it should take. You won't need to fertilize your new tree or prune it for at least a year.
Best wishes with your new live oak!
