The way you decribe the leaves makes me think of thrips.
Damage is cosmetic and the culprit has usually come and gone by the time you
notice the characteristic curled leaves.

We have several online means to help you diagnose problems. First is the monthly
timely tips column: if you had scanned the March column for issues with
leaves,you would have been led to the above site.

Another great website is UA's Urban Integrated Pest Management
They also discuss thrips at http://ag.arizona.edu/urbanipm/insects/thrips.html

Sometimes its hard to know why some trees are hit and others aren't. If you
don't believe that thrips are your problem after perusing this, let us know and
we'll continue troubleshooting.
