It might be red or silver maples or other really early trees if they have started blooming, but in my area allergies right now tend to be caused by molds as the ground and old plant matter is exposed and then March winds blow mold spores around.

Oh....yes, we have silver maples - I just hadn't seen any bloom on the trees yet, but, maybe I should look up more...lol. He definitely was reacting and felt better in the house for a few hours, then as soon as he went outside again, he was sneezing and filling up.

Our ground is SO dry right now, we put the hoses out today and I'm going to start watering already. A rarity this early. Thanks for the quick reply!

I've been getting pollen alerts from pollen.com saying that there's pollen from junipers and poplars around.
