|Trees planted on a slope are at a disadvantage in terms of receiving adequate water - it normally runs off before it has a chance to soak into the soil and wet the rootmass. Try building a watering well or watering basin beneath each, making the ridge on the basin higher on the sloping side so it will hold several inches of water. Then fill the basin, allow to drain, then fill it a second time. Watering in this manner will concentrate the moisture directly over the root mass and allow it to trickle down and wet the entire root system. Once a week should be fine. Hope your trees perk up soon.
