Watering is the work that matters most
A newly planted tree has a small root ball and cannot yet reach water deeper in the soil. Until roots spread, usually over the first two to three growing seasons, the tree depends on you. Water deeply and less often rather than a daily splash: a slow, thorough soak encourages roots to grow down, while frequent light watering keeps them shallow.
Through dry spells, check the soil at the root ball before watering. If it is dry below the surface, water; if it is still damp, wait. Reduce watering as autumn cools, and let the tree harden off before winter.
A simple field check
Push a finger into the soil at the edge of the root ball. Dry and crumbly means water now. Cool and damp means leave it. This beats any fixed schedule because it responds to the weather the tree is actually getting.
Mulch, stakes and guards
Refresh the mulch ring
Keep a flat ring of mulch a few centimetres deep around the tree, pulled back from the trunk. Top it up as it breaks down, and never let it bank up against the bark.
Loosen or remove stakes on time
Stakes steady a tree through its first season, but a trunk that is never allowed to flex stays weak. Check ties so they do not cut into bark as the trunk thickens, and remove stakes once the tree stands on its own, often after the first year.
Watch trunk guards
Guards that protect against mowers and rodents also need checking, since a guard left on too long can girdle a thickening trunk.
When a municipal permit applies
Rules differ by city, but a few patterns hold across Canada. Trees on public land — boulevards, parks, road allowances — are managed by the municipality, and residents generally cannot remove or heavily prune them without permission. Many cities also regulate larger trees on private property through a private-tree by-law, often defined by trunk diameter at a set height.
- Planting on a city boulevard usually needs municipal approval or is done by the city.
- Removing a public tree almost always requires permission.
- Removing a large private tree may need a permit where a by-law sets a size threshold.
- Heritage and protected trees can carry additional restrictions.
Check the threshold before you cut
Where a private-tree by-law exists, it is usually tied to trunk diameter measured at a defined height. Measure first and read the local by-law, because removing a regulated tree without a permit can carry penalties. Your municipality's urban forestry page is the authoritative source.
A seasonal rhythm
-
Spring
Refresh mulch, check ties and guards, resume watering as growth starts.
-
Summer
Deep-water through dry spells using the soil check rather than a fixed schedule.
-
Autumn
Taper watering, clear debris, remove stakes if the tree stands firm.
-
Winter
Leave the tree dormant; inspect guards against rodents and salt spray near roads.
