It is hard to give advise without knowing your soil. Being it is new property for you I would do a percolation test on your soil to know the extent of your problem. Google soil percolation test for directions. Al

You can dig it up and improve the soil but it will not help with the transplant shock. It is always a bummer on year 1 and, assuming the soil remains moist, it should recover on its own by nighttime or next morning. Make sure you water the soil early in the mornings once a week (1 gallon) while the summer months are here. At least on year 1 since its root system is limited and the roots cannot reach the water. You can try to temporarily provide shade for a few days/weeks until the plants are used to being outside. Obviously, try to prevent any neglect and/or any soggy soil this year. Use the finger method daily for 2-3 weeks (or a soil moisture meter) to determine when to water. When the soil feels almost dry or dry to a depth of 4", water (1 gallon) and make a note in a wall calendar. After 2-3 weeks, determine about how often you were watering (say, every 3 days? 4 days? etc). Then set the sprinkler/drip to give 1 gallon of water on that same frequency. During the summer, consider watering by hand once a week or so to all the water falls were the roots are growing. If the temps change 10-15 degrees and stay there, retry the finger method to see if you need to tweak things. I normally increase the amount of water in July to 1.5 gallons and reduce it back to 1 gallon when temps decline in the Fall. Then, on dry Fall/Winters, water once a week or once every two weeks once the plant is dormant and provided the soil has not frozen.
