Are you watering enough? Can you describe how you planted it?

Watering everyday due to heat approximately for a few minutes have planted many plants only one having problems with. Dug down twice width on a slight hill used top soil and mulch to surround it!

Have you actually checked how deep into the soil the water is seeping? Often a couple of hours less often and at a slow trickle will be more effective than a few minutes every day. You won’t know whether the moisture is getting down into the tree’s root zone unless you actually dig a small hole to see if the soil is moist farther down where the roots are. Check both the native top soil and the rootball since sometimes the original potting soil is enough different in texture from the native soil to create water movement issues and you have a wet rootball in dry soil or visa versa.

Cther issues might be the way the roots grew and care at the nursery or even unsuitability to your climate.

Blue atlas cedar is not very happy in HOT climates.

Since they are native to North Africa, they can take plenty of heat :-) But not so much high humidity.

Looks worse today before and after
