Perennial Ryegrass

What is Perennial Ryegrass?

Perennial ryegrass (Lolium perenne) is a type of cool-season grass commonly used in lawns, sports fields, and pastures. It grows quickly and has a dense, lush appearance, making it a popular choice for ground cover in temperate climates.


Why do I have an intolerance?

Ryegrass pollen is a well-known allergen and can lead to seasonal allergic rhinitis, commonly known as hay fever. During late spring and early summer, ryegrass releases pollen into the air, causing symptoms like sneezing, itchy eyes, nasal congestion, and respiratory issues in those who are sensitive.


What can I do about it?

To minimize exposure, avoid grassy areas during peak pollen season, particularly on dry and windy days. At home, keeping windows closed and using HEPA filters can reduce pollen levels indoors. If your lawn contains ryegrass, consider reducing outdoor activities in the morning when pollen levels are highest.
