It’s just the pine trees. The pollen from the southern pine trees is too big to be an allergic problem for most people, but it does coat EVERYTHING and about three weeks later we have to hose down everything outside (porch, deck, chairs, grills, cars). Pine trees in the SE are a crop and they are also the most prevalent naturally occurring tree, they spew out a LOT of pollen every spring and this is the earliest I can remember. My dogwood and azalea’s are popping, peach trees already bloomed and done with, elm about halfway there.
I’m halfway between Greenville and Columbia, SC and I don’t EVER remember the spring coming so early. Luckily I don’t have any allergen’s so I just watch while other folks suffer and spend hours in April cleaning my dang cars and outdoor stuff when it’s over.
