Apricots are much hardier than most people think. The dormant trees tolerate cold temperatures as low as -20° F, or a typical USDA Zone 5 winter. However, because they have a low chilling requirement (400 to 900 hours), they respond to any warm period in late winter or very early spring by bursting forth with blossoms that are then easily killed by a frost. The longer you keep the trees from blooming, the more likely it is they'll escape a late frost.
Make Them Bloom Later
To encourage your trees to bloom late, plant them where they'll stay cool in the spring. The north side of a building is a good location. Set the tree where it is shaded in the spring: as the sun gets higher in the summer, it will get plenty of light. You can also delay blooming by mulching the roots heavily in late winter so the soil will thaw later. Some years it may be too cold for bees to be out pollinating when apricots bloom, which could limit the crop. Some smaller insects do come out and pollinate blossoms whenever temperatures rise even for a short period. Because these insects don't fly very far, you may consider planting a few apricots closer to each other than the 25-foot distance usually recommended.

how much to water is very dependant on species, size of tree and weather you want survival or rapid growth........and the time of year.
at the very least dig down a bit once a week to see if still moist.........if you want growth i would aim for 50 liters per week per square meter of dripline area in the summer.....if the tree is huge the amount of water could be large so just go with what you can.
also micro swales could be used like feeder channels to fill the holes when it rains.......use a bit of slope......not on contour.
the problem with sawdust in a deep hole could be things getting anaerobic (no air) wood chips are nice and chunky and let air down the hole.......lets say no more than 10% mixed with chips
a smaller auger may be easier to use just use more number of holes.
