Cedar pollen, live oaks and winter dust
Winter in this part of Central Texas brings pollen from Ashe juniper, locally called cedar, and a yellowish film settles on cars, windows and fences. Spring adds oak pollen and the long catkins that fall onto driveways and stick when damp. Both leave marks that dull a house exterior until they are washed away.
Cedar Park also has many mature trees along creek corridors and greenbelts. Leaves and shade keep fences, decks and the roof damp, which feeds algae and mildew. A spring clean after the pollen peaks, and a second look in fall, keeps buildup from getting a firm grip.
