Sep 03, 2025

Understanding the Calgary Climate

Preparing your garden for winter in Calgary requires a strategic approach due to its unique climate. The city experiences cold winters, often with snow and frost. Therefore, it is essential to begin preparations in the fall to ensure your garden survives and thrives after the harsh winter months.

Calgary's climate is characterized by Chinook winds and sudden temperature changes. These conditions can be challenging for gardeners, making it crucial to protect plants from extreme cold and fluctuating temperatures.

Cleaning and Clearing Your Garden

Before winter sets in, it's important to clean and clear your garden. Begin by removing dead plants, leaves, and debris. This not only tidies up the space but also prevents pests and diseases from taking hold in the decaying material.

Consider composting the organic matter you clear. Composting provides you with nutrient-rich soil for the next growing season. Be sure to remove any invasive weeds completely to prevent them from returning in spring.

Pruning and Trimming

Pruning and trimming are crucial steps in preparing your garden for winter. Cut back perennials to a few inches above the ground. This helps prevent disease and encourages healthy growth in the spring.

Trees and shrubs should also be pruned to remove any dead or diseased branches. Doing so can prevent damage from heavy snow and ice accumulation during winter storms.

Protecting Your Plants

To shield your plants from the cold, consider adding a layer of mulch around the base of your plants. Mulch acts as an insulator, keeping the soil temperature stable and preventing frost heaving.

For more delicate plants, think about using burlap or frost cloths to cover them. This extra layer of protection can be crucial for plants that are not naturally suited to Calgary's winter conditions.

Watering Wisely

Ensure your plants are well-watered before the ground freezes. Adequate moisture helps plants withstand the drying effects of winter winds. However, avoid overwatering, as waterlogged soil can lead to root rot.

A deep watering session before the first major frost is recommended. This will help your plants enter dormancy in good health, ready to bounce back when spring arrives.

Preparing Garden Equipment

Don't forget to prepare your gardening equipment for winter as well. Clean and store tools properly to prevent rust and damage. Drain hoses and irrigation systems to avoid freezing, which can cause cracks and leaks.

If you have garden furniture or decorations, consider storing them indoors or covering them with weather-resistant tarps. This step ensures they remain in good condition for the next season.

Planning for Spring

While preparing for winter, it's also a great time to plan for the upcoming spring season. Consider making notes about what worked well in your garden this year and any changes you'd like to implement next year.

By taking these proactive steps, you'll ensure that your Calgary garden is ready to flourish once the warmer weather returns.
