Answer: Fruit trees can take several months to become established and the only thing you need to do is to water them deeply once a week (twice if the weather is really hot). Daily watering is too much, even for sandy soil. When you water that often you run the risk of depleting the soil of oxygen - something the roots of your trees need. So, if you haven't already, make a watering well or basin beneath your new trees by mounding up a few inches of soil in a circle about 12" in diameter. When you water, fill the basin, allow it to drain, then fill it a second time. This will concentrate the moisture over the rootmass and allow it to trickle down, wetting the rootmass. You can water this way, then wait 3-4 days and dig down into the soil. If it is still moist 1-2" below the surface, you won't need to water for a few days. If it is dry, it's time to water.
By next spring both your trees should be fully established and should leave out without problem.
