Answer: You'll want to water deeply once each week to help the roots of your new pine become well established. I find the best way to do this is to build a watering well or basin directly beneath the plant by mounding up a few inches of soil. Fill the basin, allow to drain, then fill a second time. This will concentrate the moisture directly over the root mass, allowing it to trickle down and wet the entire root mass each time you water. Once a week should do it - twice a week if the weather is really hot.
Best wishes with your new pine!
