10 Tips to Winter-Proof Your Garden in Ontario

Understanding Ontario’s Winter

The first step in gearing up for winter is understanding what you’re up against. Ontario’s winters are as breathtakingly beautiful as they are brutal.

Climate Challenges

Ontario often faces sub-zero temperatures, intense snowfall, and strong winds. These climatic nuances play a significant role in determining which plants thrive and which ones struggle. While snow acts as an insulating blanket for the soil, frequent thaw-freeze cycles can damage plants.

Predicting First Frosts

Being forewarned is forearmed. Keep an eye on local weather predictions. Knowing when the first frost will hit allows gardeners in Ontario to take preventative measures in time.

Pre-Winter Soil Prep

Laying the groundwork, quite literally, is essential for a garden’s winter success.

Enriching with Compost

Before the ground freezes, enrich the soil with well-decomposed compost. This not only boosts the soil’s nutrient content but also improves its structure and drainage.

Mulching Magic

A thick layer of mulch acts as a protective barrier. Mulching prevents the soil from freezing quickly, protects plant roots, and conserves moisture. Organic mulches also enrich the soil as they decompose.

Right Plant Selection

The plants you choose can make or break your winter gardening game.

Native Plants Benefits

Native plants have evolved to thrive in Ontario’s climate. They’re naturally resilient to local pests, diseases, and climatic conditions.

Avoiding Tropical Plants

While they might look appealing, tropical plants aren’t cut out for Ontario’s winter. It’s best to steer clear or bring them indoors during the colder months.

Shielding the Delicates

Your delicate plants will need some extra TLC to see them through the winter.

Frost Cloths

These are the superheroes of winter gardening. Draping your sensitive plants with frost cloths can shield them from light frosts and icy winds.

Temporary Greenhouses

For those who can invest a little more, setting up a temporary greenhouse can provide plants with a controlled environment, protecting them from the harshest of winter conditions.

Winter Watering Wisdom

Watering during winter is a tightrope walk – you don’t want to overdo it, but you can’t neglect it either.

Moisture Retention

Ensuring the soil retains just the right amount of moisture prevents plants from drying out. Using a layer of mulch can help with this.

Avoiding Overwatering

Excessive water can lead to root rot, especially if the soil is cold. Always check the soil’s moisture level before watering.

Lawn Care in Cold

Your lawn, too, needs special attention during the colder months.


A late fall feed with a high-quality fertilizer prepares your lawn for winter, ensuring it springs back to life once the weather warms up.

Mowing Techniques

Mowing your lawn slightly shorter in the lead-up to winter can prevent snow mold and other fungal diseases.

Guarding Trees and Shrubs

These hardy plants also need some safeguarding from the winter chill.

Pruning Practices

Prune away dead or damaged branches to prevent them from breaking off under the weight of snow or strong winds.

Wrapping and Insulating

Young trees or those with thin bark can benefit from being wrapped. It protects them from frost cracks and sunscald.

Plant Bed Maintenance

Your plant beds are the crux of your garden and warrant meticulous care.

Weeding Out

Getting rid of weeds ensures they don’t rob your plants of essential nutrients during the crucial winter months.

Layering with Leaves

A layer of fallen autumn leaves acts as an excellent insulator for plant beds, preventing rapid temperature fluctuations.

Preparing Perennial Plants

Perennials are the backbone of any garden. Ensuring they survive the winter ensures a vibrant garden year after year.

Root Protection

Perennial plant roots are susceptible to freezing. Mulching and proper watering can help protect them.

Deadheading and Pruning

Remove spent flowers and prune perennials to ensure healthy growth in the spring.

Garden Tool Care

Your tools have served you well throughout the growing season; now it’s your turn to care for them.

Cleaning and Storing

Clean all your tools thoroughly to remove soil and plant residue. Store them in a dry place to prevent rusting.

Winter Repairs

Winter is a great time to sharpen blades, oil moving parts, and repair any damages to your gardening tools.

Frequently Asked Questions

How do I protect my potted plants during winter?

Potted plants are more susceptible to cold since their roots are less insulated. Consider moving them indoors or clustering them together and covering with frost cloth.

Is it okay to water plants on a sunny winter day?

Yes, but ensure the soil isn’t frozen. Water early to give plants ample time to absorb it before temperatures drop in the evening.

Should I remove snow from my plants?

While snow can insulate plants, excessive accumulation can break branches. Gently brush off heavy snow but avoid shaking plants which can cause damage.

Which plants are most vulnerable to frost?

Tropical plants, succulents, and some annuals are particularly frost-sensitive. Always check the specific requirements of each plant species.

Do I need to fertilize my garden in winter?

Most plants are dormant during winter and don’t need fertilization. However, a late fall feed can be beneficial for some plants and lawns.

Can I start planting during late winter?

Late winter is an ideal time to start seeds indoors. By the time spring arrives, you’ll have young plants ready for transplanting.


Winter-proofing your garden in Ontario might seem like a daunting task, but armed with the right knowledge and a sprinkle of determination, you can transform the winter months from a gardening nightmare into a dream of spring’s promise. Your garden will not only survive the cold but will also burst forth in a riot of colors and growth when the next season rolls around.

Remember, every snowflake is a promise of rejuvenation, and every frost, a testament to nature’s resilience. Your garden is no different. Happy gardening!
