Heat stress is a good possibility.  First move the wood chips away.  Wood chips touching plants during hot windy weather can quickly dehydrate plants. Water at the root level.  Watering leaves can be counter productive.  And finally with so much wood nearby stepping near the plant may have dislodged it from the soil. Personally I would plant it in a container for a couple of weeks and then sink the container into the soil for the winter.

Also curled leaves can be a sign of herbicide damage if herbicides were applied nearby and drifted over.
