The oak tree pollen drop lasts about four days. It is this yellowish dust that is seen on car hoods and deck floors, and causes problems for people with seasonal allergies. Heavy rains and humid conditions may delay the release of pollen and affect the number of acorns produced on a single tree. Other weather conditions, such as a late-spring frost, can also severely impact a season's acorn crop, which in part explains why backyards are littered with fallen acorns some years and not others.

If all the conditions for germination are met, a fallen acorn will sprout where it landed. It first sends a taproot into the soil, and not long after that, a single stem emerges from the end and opens into the cotyledon, which looks like a small pair of leaves but is actually an external extension of the acorn's embryo.

This is called the pollen-food allergy syndrome formerly known as the oral allergy syndrome and occurs when the immune system in your mouth mistakes certain raw fruit and vegetable proteins for pollens that you are allergic to. One way to fight this is to simply peel your raw fruits or vegetables and cook them at least the ones that can be cooked which will lessen or help you completely avoid a reaction. Proximity to the trigger trees.

If you have one of the culprit trees in your yard, you are, of course, more susceptible to allergy symptoms and reactions.
