Cottonwood trees spread very tiny, wind borne particles that can affect allergies for people miles around. These trees typically pollinate during the spring along with other tree allergens like ash and oak.
Cottonwood pollen is most prevalent during March to May.
Cottonwoods are deciduous trees that can be found in nearly every state in the U.S. The trees are known for their rapid growth and ability to adapt to a variety of environments, making them excellent for landscaping, windbreaks, and lumber. However, cottonwoods also produce an abundance of pollen each year that can trigger allergic reactions in some individuals.
Cottonwood pollen is typically prevalent in the spring, from March to May, varying slightly depending on the location and climate. During this time, the trees release large amounts of pollen into the air to fertilize other cottonwood trees.
Cottonwood pollen is especially prevalent in areas with large cottonwood populations, such as along riverbanks or in areas with agricultural irrigation.
It’s important to note that these trees typically pollinate during the spring along with other tree allergens like ash and oak. People suffering with allergies during the spring months may want to consider getting an allergy test to diagnose exactly which pollen they’re allergic to.
