Allergy Facts
Many people believe that mowing their lawn prevents it from going to seed and therefore reduces the amount of pollen the grass plants produce. Unfortunately, the reproductive organ of several species of grass plants are low to the ground and escape the mower's blade. This ensures a continuous source of pollen right outside your window.
