Quack Grass

What is Quack Grass? 

Quack grass (Elymus repens) is a perennial grass species often regarded as a weed due to its invasive nature. It spreads quickly via underground rhizomes, taking over gardens, lawns, and agricultural land. Native to Europe and Asia, it’s now found in temperate regions worldwide. Quack grass is easily recognizable by its flat, rough leaves and thick, horizontal roots that make it difficult to control once established.

Why do I have an intolerance? 

People can experience an allergy to quack grass pollen, which is known to trigger hay fever symptoms. During late spring and early summer, quack grass releases pollen into the air, leading to respiratory reactions like sneezing, itchy eyes, runny nose, and wheezing in individuals sensitive to grass pollens. In addition, touching the grass may cause skin irritation in some people.

What can I do about it? 

To manage a quack grass allergy, avoid outdoor activities during peak pollen release times, particularly on windy days. Using protective masks and glasses can help reduce exposure when outdoors. Indoors, keeping windows closed and using HEPA filters can minimize pollen entry. Over-the-counter antihistamines and nasal sprays can be effective in managing symptoms, as can allergy shots in severe cases.
