Spring can be a struggle for many people. It is estimated that over a quarter of adults in the US have seasonal allergies, which means more than 80 million people are affected. Their struggles are often exacerbated because some of the most pollen-producing trees have long been used in suburban landscaping.
The worst offenders are wind-pollinated trees. Male cultivars have been routinely favored over the years for landscaping, as they don’t drop fruit and make a mess on roads and sidewalks. However, it results in these trees shedding huge amounts of pollen into the air each spring.
