When is alder tree pollen season?

Since alder trees are in the same family as birch trees they are very similar. Like birch tree pollen, alder tree pollen is produced by their flowers, called catkins, which is released in the winter, as early as January, to  spring depending on climate. Catkins are a long spherical flower that doesn’t actually look like a flower (see the picture above). Once the alder tree pollen is released it’s carried by the wind for the purpose of pollinating the female part of the tree for reproduction, also called a catkin. Unfortunately, the wind also blows alder tree pollen into your home, on your clothes, and into the air where it will enter your nose, throat, and lungs. For this reason, many people experience allergies to the birch tree pollen.
