Big investment and a nice tree.

The trick is to get water to the rootball. Unless you stick your fingers in the dirt, who knows. Someof these lazy yahoos plant these things w/o slicing the burlap off the sides of the balls. They even leave wire mesh in place lol. Not a death sentence but each might be another 5 or 10 percent off survival chances.

Regardless, you want to plant in fall or early spring so ya may as well give it a chance. (Yeah, planting mid May was another 10% off survival, mid July maybe 50% !)

I say if it releafs fairly well this summer you are ok.

So, go take some pics of your tree and post them.

Try to snap a lower twig and see if it is brittle.

Take a pic of where your tree's trunk meets the soil and post it.

Stick your finger in the rootball until you find roots and see if it is wet or dry.

I will hazard to say with any Acer rubrum cultivar it is difficult to over water. The call the fellows swamp maple some places.

Good luck.

Photos flipped when uploading - sorry! Thanks for responding!

if the roots are working.. i can releaf.. and only time will tell ..

Too late for you, OP, but this example is demonstrative of our constant admonitions to plant small. If you could imagine say, a neighbor to you, planting the exact same species, in exactly the same conditions, but instead of you big $500 job, just an easily handled specimen of perhaps 5 ft. in height, in time, the little 5-footer would-in many, many cases overtake the big guy in growth rate, it suffering far less transplant shock. The myth of instant gratification via moving very large trees is mostly false.
