Maintaining lush and vibrant lawns in Calgary’s changing weather patterns can be quite a task, with regular watering and mowing being only part of the solution. Lawn fertilisers are pivotal in keeping green spaces healthy and beautiful; let’s dive into their world, their benefits, and any special considerations relevant to Calgary’s climate.

What is Lawn Fertilizer?

Understanding Lawn Fertiliser

Lawn fertiliser in Calgary is an essential product that provides nutrients to grass and soil for growth and health, creating lush, green lawns that can withstand disease and drought stressors. Understanding the composition of lawn fertilisers is vital in making an informed decision explicitly tailored to your yard.

The Nutrient Trio: NPK

The majority of lawn fertilisers contain three essential nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K), collectively known as NPK.

  • Nitrogen fuels the leaf and stem growth, keeping your lawn vibrant green.
  • Phosphorus supports the development of the root system, flowers, seeds, and fruit.
  • Potassium enhances plant health by boosting its resilience to diseases, drought, and frost.

The Benefits of Lawn Fertilisers

A Greener Lawn

Fertilising your lawn regularly is one of the easiest and most aesthetically pleasing ways to create an enticingly vibrant green lawn. Nitrogen, the essential nutrient of most fertilisers, fuels grass growth for its dynamic appearance.

Improved Lawn Health

Fertiliser not only beautifies your lawn but also enhances its overall health. A well-fed lawn can more readily absorb nutrients from water sources and absorb pesticides and disease more effectively than its counterparts.

Reduction in Weeds

A properly fertilised lawn typically features dense grass cover that leaves little room for growing weeds. Furthermore, some fertilisers contain weed preventatives to help your grass remain free of weeds.

Fertilising Lawns in Calgary: A Unique Challenge

Calgary’s climate poses unique challenges regarding lawn care, with cold winters and hot summers creating stress for grass. Selecting and applying the appropriate type and fertiliser at the proper times can ensure your grass thrives throughout the year.

Cold Tolerance

Calgary’s long winters can put tremendous strain on your lawn. Potassium-rich fertiliser helps strengthen grass’s tolerance to frost and cold weather, aiding overwintering and spring green-up processes.

Drought Tolerance

Calgary summers can be hot and dry, putting stress on your lawn. Regular fertilisation can increase its ability to endure drought by strengthening its root system to access deeper water sources.

Disease Resistance

Weather fluctuations in Calgary can expose lawns to various diseases. A balanced fertiliser program can strengthen lawn health, making it more disease resistant.

Fertilising Your Lawn: Best Practices

Soil Testing

Before fertilising your lawn, soil testing is vitally important. Doing this will allow you to assess which nutrients your grass requires and select an effective type of fertiliser.

Fertiliser Selection

Selecting an ideal fertiliser is critical. Consider your lawn’s unique needs before making your selection; for instance, a phosphorus-rich fertiliser could be more appropriate if its growth has slowed; alternatively, nitrogen-rich products could provide solutions if its colour remains dull and slow-growing.

Timing and Frequency

Fertilising your lawn at its peak growth stage – usually spring – is best. A second application in fall can help prepare it for winter weather conditions in Calgary’s climate, while additional applications may also be helpful during hot and dry summer days.

Application Technique

Spread fertiliser across your entire lawn evenly to avoid burning or over-fertilising certain areas, with the assistance of a spreader for even distribution.


Safety and Environmental Considerations

Lawn fertilisers can have both positive and negative impacts if not used appropriately. Over-fertilising can lead to runoff that pollutes local waterways.

Environmentally Friendly Practices

Consider organic or slow-release fertilisers to minimise nutrient runoff risks. Be wary of application rates, and try applying fertiliser when no rain is expected, as water may wash away any vital nutrients.

Safety Measures

Keep pets and children off the lawn during and immediately after fertiliser application to avoid accidental ingestion of fertilisers. Keep all fertilisers stored safely to prevent accidental consumption.


Nourishing your Calgary lawn can be a unique challenge, but with knowledge and fertiliser, you can create a vibrant green space. While fertilisers shouldn’t replace good lawn care practices, they do help achieve lushness year-round while helping create resilient lawns with flourishing flowers and resilient edges. By continuing fertiliser use and adherence to best practices, you’ll notice a dramatic improvement in its health and appearance over time.
