Have you checked the moisture content of the original rootball? If so, is it dry, moist or wet?

Likely you need to drizzle water directly onto the original rootball.

So you mean dig it out check the moisture there, water and replant?

No. Stick your finger into the rootball where it now is.

When was it planted, and was it purchased as a potted or bare-root plant, or was it dug up and given to you? Basically, how much of the root mass was lost before you planted it.

I would feed it miracle grow food every few weeks but that hasn't helped either. I assume you meant I did feed it every two weeks -

You have over fertilized your plant. - this will inhibit the roots from taking up water. OR CAUSE IT TO WILT.

STOP the MG.

Hopefully it survived the summer fertilizer treatment. And the soil is not flushed free of the N P K.

I rarely fertilize my plants, and when I do it is a granular organic fertilizer.

Is there any mulch below the surface? (There shouldn't be unless/until it naturally it works itself there.) These few chips of wood do not constitute having mulched. That would require at least 1 whole bag in a circle around the tree, as far out as it will spread at a depth of 2-5 inches, depending on average particle size. For pieces of wood that size, I'd go with a thick layer, and probably 2 bags, making a circle at least as wide as the drip-line of the canopy. There's never a wrong time to add a layer of mulch, unless the ground is muddy and you're trampling footprints.

However, looks like there's some grass trying to creep in on what you already cleared for this planting. If you put a layer of overlapping cardboard around the base (no closer than necessary to suppress what's growing around it,) under the mulch, you won't have to worry about the grass growing up through the mulch, which it certainly will if not smothered or pulled first. Then installing a little border around the mulch, to separate grass area from mulch area, will keep both on their side of the line.
