Factors to consider before planting a tree
All species possess special requirements, benefits, and vulnerabilities. Research before purchasing, preparing the site, and planting the tree.
1. Hardiness zones: Canada is divided into eight growing zones. Browse Agriculture Canada’s website to find yours.
2. Evergreen or deciduous: The former keep their needles (leaves) all year while the latter drop them in autumn.
3. Shade or full sun: Trees need light. What’s your site like?
4. Soil conditions: Some trees thrive in acidic soil, others require alkaline soil. Test your soil—and identify what trees are thriving nearby. (Tip: ask your neighbours and build community rapport!)
5. Siting issues: Don’t plant too close to any built structure, be it your home, garage, fence, carport, sidewalk, laneway, weeping beds/septic tank, dog kennel or overhead wires.
6. Food factors: Want to harvest a crop—or provide food for wildlife?
7. Natives: Like Colallilo advised, choose indigenous, local trees over introduced and potentially invasive species. Browse the Canadian Wildlife Federation’s website for ideas.
8. Healthy = safe: Avoid saplings with defects such as damaged branches or trunks. A healthy root ball is important.
9. Human health: Many people are allergic to pollen. Avoid species such as Russian olives and poplars.
10. Municipal bylaws: Check out potential legal issues before purchasing.
