As March unfolds, it brings the promise of spring—but also the return of seasonal allergies.

While pollen gets most of the blame, another hidden culprit lurks beneath the melting snow: snow mould. This lesser-known allergen thrives under snow cover during winter and is released into the air as the snow melts, triggering sneezing, congestion, and itchy eyes in sensitive individuals.

In cities like Calgary, where snow lingers for months, snow mould can be a serious trigger for seasonal allergies. Beyond its impact on health, it also wreaks havoc on lawns, leaving behind unsightly dead patches. Fortunately, there are ways to reduce its effects on both your allergies and your yard.

What can you do to reduce the effects of this pesky pathogen on your seasonal allergies?

In the Fall, when the grass starts turning yellow, mow down your lawn to under 1.5 inches to prevent matting.

Thoroughly rake your lawn to reduce thick patches and improve air circulation. If you’ve decided that snow mould IS your worst enemy, there are fungicide treatments available for your lawn.

Tackle these seasonal allergens like you would with any other airborne irritant.

Consider using an air purifier indoors, and change your furnace filter if it’s been a while. Shower and change your clothes if you’ve spent some time outdoors to prevent the spread of spores to the rest of your home.

If you’re considering fertilizer, this is the time to think about the ratios you’d want to use. Higher potassium and phosphorus as opposed to nitrogen in the soil will help in preventing formation later on.

Anti-histamines, nasal sprays, decongestants, and eye drops are handy to have to treat seasonal allergy flare-ups. Our pharmacists can take the guesswork out of finding the correct product for your lifestyle and symptoms.
