Harland boxwood - yellow leaves

Dear IBC,

two weeks ago I repotted my harland boxwood into a new, bigger pot with well drained soil. Previous one was too small with sandy soil in it and the root ball was very tight.
Two days ago I've noticed a yellow leaves on a tree? I didn't cut any roots, plant is watered heavily once a day, placed in shade / sometimes full sun. Please tell me what could be a reason of this withered leaves.

Regards,

Even though you didn't cut any roots it may be simply transplant shock -- especially if you bare rooted it. I assume you did bare root since you were changing the soil. In addition, this is not the optimal time to be repotting -- especially if it has had its roots bared. It probably does NOT need any sun at this point.

Hello Jim,

thanks for you reply, and yes, it is not a good time to repotting, but plant grew up in small pot.
The problem was that the half of pot high was a root ball, another half - soil. Roots hasn't got a good conditions so I've decided to repot even its a not a time for that.
Root ball didnt contained any soil, so there wasn't a reason to bare roots so much, only extricate the rootball edges.
I hope that this wont affect on plant health in future.
