Tree pollen is a fine powder produced by trees during their reproductive cycle. It contains male gametes that are essential for fertilizing female flowers. Different tree species, such as oak, pine, and maple, release pollen at various times of the year, often in spring. This pollen can travel long distances through the air, contributing to the growth of new trees. While tree pollen is a natural part of the ecosystem, it can also trigger allergic reactions in some people. Symptoms may include sneezing, runny nose, and itchy eyes. Understanding tree pollen can help individuals manage their allergies during peak seasons.
