A picture of the bushes would be more helpful.

Here's the Duke....
Thanks for help

....and here's the Bluecrop. The Biloxi are just brown stick now.

Thanks again!

Most of the blueberry problems are Ph related. Have the soil ph tested.With a high Ph, the plant can't absorb water. So the plant will be always under stress.

In its native setting, such as NJ Pine Barren, wild blueberry bushes grow under tall trees. Very deep composted leave layer is like peat moss and holds a lot of water. The Ph is low. So the wild blueberry just thrives there.

You mention that you've kept them moist, zebra4, but have you dug down and confirmed that that the peat is staying evenly moist below the surface? Based on what you wrote, I'm assuming that you dug your planting hole, filled it with peat, and then planted the bush? It's generally not a good idea to completely replace the native soil but instead to blend native soil with amendments. That helps mitigate the risk of ending up with a root zone that stays too wet or too dry. Since peat can potentially hold too much water, especially if the surrounding soil is slow to drain or if you have a high water table, and that, conversely, it becomes hydrophobic if it dries out too much, the problems that you're seeing could very easily be water related -- either too much or too little. They might not be, but that's a good place to start...
