Allergies come in different forms, so not everyone who has a pollen allergy is allergic to tree pollen. A palm tree allergy is indicative of your bodyâs reduced immunity to pollen, which can sometimes be genetic. When your body comes into contact with tree pollen, it releases histamine, the aggravator of common allergy symptoms. There are certain types of palm trees that donât exhibit pollen, such as Phoenix palms, so it is always important to identify the differences before planting any new trees in your yard.
The species that produce these huge volumes of wind-dispersed pollen (pines and oaks, for example) are the species that usually cause problems for people with allergies.

For example, rain dampens pollen, preventing its flow into the air, and an unexpected freeze can slow a tree's pollen production.ry clothes in an automatic dryer rather than hanging them outside to avoid pollen collecting on clothing and being carried indoors.
