Spring is a wonderful time of year, but for allergy sufferers it can mean several months of misery. The main culprit is tree pollen which can fill the air and lead to runny noses, itchy eyes, coughing, and wheezing. The months of March and April are especially difficult since several kinds of trees release pollen in large amounts during this time of year.1

Fortunately, not all trees produce pollen that can be easily dispersed by the wind. Many fruit-bearing trees and ornamental trees are pollinated by insects and are less problematic for those with pollen allergies.

The following chart lists the allergenic trees that cause problems for most people with an allergy to tree pollen. Clinics that offer allergy skin testing should have these and other outdoor allergens on their panel to provide a comprehensive diagnosis for pollen allergy.2
