Sango Kaka fried over light?

Yes my Sango Kaka reminds me of Dr. Seuss story of fired green eggs. The leaves on the top of this four and a half foot tree are turning yellower each day, as I am typing this the temperature is 98 degrees. The leaves on the bottom are not yellow, maybe because they are shaded buy the top leaves. So I presume I should put shade cloth over it and plan to move it next fall. I installed this tree in this afternoon sun because of, I guess bad advise from the tree farm. They said they had one in full sun all day with out any problems. So my question is should I cover it and plan on moving it. I think I am giving it enough water, I put the hose to it for a couple of hours or so, every week.

PS: Would it be a good idea to wait until the soil temperature is below 50 degrees to avoid active unwanted fungal and biological activities. I could prepare the site before hand inoculate the soil with probiotics and pro-fungi allowing the tree to have the nutrients ready on site, then the tree could start the recovery process form the transplant and offer it the protections of a cooler soil.

 

Tree farm may be watering vicinity alot during day, thus cooling it.

 

Yea, I never though of that, but their irrigation is drip or over heads at night, it probally gets twice the water that mine get simply because they don't pay for there water like I have to, and with the bit of irrigation I do requires me to pay a very fat water bill every other month.

 

I had this exact same thing happen to me last year. I lost a large oak which shaded an A. palm. 'Crimson Queen' and then the combination of too much sun and a drought and even this established maple burned up just like yours-fried on the top layer, but leaves that were shaded underneath were fine. I noticed the branches stayed healthy looking, so I was hopeful that the next year they would bud out and be okay. This year (zone 5) I had a lot of dieback on those branches, which you probably wouldn't have to worry about in Virginia, but they have sprouted out nicely and even though we have been in the upper nineties a couple times they aren't burning this year. I'm not saying don't move your tree, but if it was newly planted last year, it might be fine next year when the root system is established. Hopefully, some other people will give their thoughts about this. Especially those more in your area.
