There are different types of pollen. Some are large and waxy, while others are light, small and dry. Light, dry pollens, which are found on certain trees, grasses and low weeds such as ragweed, are easily picked up and disseminated by air currents and wind. This is the type of pollen that triggers allergies and allergic asthma.
During the late spring and summer, grass pollens are more likely to trigger your symptoms. Common grass allergens include:
- Bermuda grass
- Orchard grass
- Red top grass
- Sweet vernal grass
- Timothy grass (pollen pictured above)
There are some easy steps you can take to avoid Timothy grass pollen.
