What Gardening Zone is Toronto?
The Toronto Gardening Zone, also known as the Toronto Hardiness Zone, falls into Zone 6.
The metro-Toronto area can further be split into Zones 6a or 6b, depending on which side of the city you live. However, trees, shrubs, flowers, vegetables, or other flora that are rated for Zone 6 are typically good fits for your home garden (given that other conditions like soil and sun/shade are favorable as well).
Plants that are rated for Zones 5, 4, and 3 are even hardier are also great fits for your Toronto garden.
Plants that are rated for Zones 7 or 8 aren’t necessarily impossible, but they are usually harder to keep, require more attention, and can succumb to a surprise change in weather patterns. And if you do manage to get a beautiful summer out of them, they won’t survive the cold, snowy winters of Toronto. These flowers are considered annuals. If your heart is set on a beautiful breed that falls into a higher category, though, you can still try it out. Just be mindful of its unique needs and be prepared to bring it indoors when weather conditions change pace.
How is the Toronto Zone for Gardening Determined?
Canada determines an area’s gardening zone based on a compilation of eight factors and the documented survival rates of various species under these average conditions. It is a complex process that helps everyone, from farmers and nurseries to people just trying to get something to grow in their home garden. The gardening zone only applies to floras that are planted in the ground. Potted plants are not insulated against weather conditions and usually need different care.
The most current Toronto gardening zone is now based on data from the eight categories above collected from the years 1981 to 2010. This compilation of information puts Toronto into its most accurate planting zone—Zone 6. When choosing your plants or plant seeds, try to stick with foliage that falls in the Zone 6 category or below—Zones 5, 4, 3, 2, or 1.
Remember, you can still get away with higher-zoned plants if other conditions (soil, air, etc.) are right and you’re prepared to bring them indoors for the winter or simply replant next year. If you’re still unsure, simply ask the experts at your local nursery. They’ll help you decide what plants might be best for you.

Other Factors to Growing Hardy, Healthy Plants
Watering is a massive factor in the health of your plants (and something a lot of people do wrong). Too thirsty, and your plants will wilt away. Too much water, and they’ll drown. Watering during the day can cause sunburn, and watering at night can promote fungal growth and disease.
Investing in a professionally-installed drip irrigation system can eliminate the mathematics of watering your plants (at least on your part) and guarantee your landscape gets precisely what it needs. A well-designed drip irrigation system will automatically saturate your plants’ roots with the exact amount of water required at the prime time of the day. It can even account for rainfall and be zoned out to provide a watering schedule specific to the needs of each area of your garden.
