New pollen invading Texas on the heels of Mountain Cedar

While mountain cedar may be the problem in January-February but “the one that is most problematic for people is live oak,” explains Dr. Dilley, and allergist in San Antonio. “That's the one that coats your car and your sidewalk with that yellow residue, and that's the one that makes people very miserable. You can expect to see live oak in mid to late march. Before live oak hits, people will start feeling the effects of the ash tree right after Valentines Day."
