Types of Trees to Plant in Calgary’s Plant Hardiness Zone
When you plant a tree, you want to see it grow tall and healthy for years. That’s why it’s essential to choose trees that’ll thrive in your climate. Established hardiness zones make it easier for you to identify the best trees to plant. Here’s a quick guide on trees that grow well in Calgary’s planting zone.
What Is Calgary’s Planting Zone?
Natural Resources Canada publishes information on hardiness zones across the country based on climate, temperature, precipitation, drainage, elevation, air quality, soil composition and sunlight. Your hardiness zone helps you determine which plants and trees are more likely to thrive in your area.
There are 10 hardiness zones in Canada, with zero being the coldest and nine the warmest. Calgary has a planting zone rating of 4a. However, experts recommend Zone 2 and 3 trees as having the best chance of surviving Calgary’s extreme weather events. You can plant trees rated for Zone 4, but they may require more care.
How to Find and Read a Zone Label for a Tree
Trees sold in nurseries and garden centres have labels with plenty of information about the species and its requirements for light, soil and other conditions. The label should also include the planting zone it’s best suited for.
