Planting trees in town road allowance

The town’s Urban Forestry section is responsible for the selection, location and planting of street trees in subdivisions south of Dundas street. Species selection is made to ensure the tree lives as long as possible. For subdivisions north of Dundas Street, the developer is responsible for the installation of street trees, and the species and location are determined in consultation with town.

In either case, planting takes place in the spring and fall of each year (after the sod is laid by the builder, for new subdivisions). The spacing and location of the trees varies and not every address receives a tree due to space limitations, diversity of soil, tree species availability and any utility obstructions such as lights, hydro poles or stop signs. All streetscape designs are approved by Council. For more information, please call 905-845-6601.

When will my new neighbourhood get street trees?

After residents move into a subdivision it may take up to three years for trees to be planted. The town cannot plant trees in areas of a subdivision that are still experiencing road construction and sod laying. New homeowners may find that there is a tree-related charge on the closing purchase of their new home. In some cases the charges have been specifically assessed by developers to builders and then passed on to the homeowner. Tree planting agreements are made between the town and the developer––not the town and the homeowner. The town does not provide refunds for street tree planting.

All street trees located on municipally owned property are protected by town by-laws.

Replacing trees in town road allowance

The Urban Forestry section is responsible for replacement trees in established neighbourhoods. Replacement trees (or infill trees), are planted in areas where previously existing trees have been removed and stumped. In some cases, the town cannot replace trees due to site limitations, species availability and budget restrictions. Trees must be planted at least 12 metres from one another.

How to help maintain your trees

The trees planted on your street were carefully chosen to provide shade, windbreaks and privacy; attract birds and wildlife; and beautify your neighbourhood. Help keep your street trees healthy by following these tips:

  • Keep lawn mowers and string trimmers away from tree trunks to avoid damaging the bark, which can eventually kill a tree.
  • Do not excavate around the base of your tree—you can easily damage the tree’s small feeder roots at the surface of the lawn.
  • Leave wood chips and mulch at the base of the tree in place––they protect the tree from damage and reduce water loss by allowing water and nutrients to enter the soil more easily.
  • Do not pile soil or grass clippings over mulch or woodchips.
  • Water slowly and deeply using a soaker hose or a sprinkler to encourage the tree's roots to grow deep, protecting it from drought.
  • Maintain a healthy lawn and boulevard.

How much water does my tree need?

The town asks residents to water street trees on the house-side of the sidewalk. All other street trees will be watered by town staff. You can encourage a tree’s roots to grow deep to protect it from drought by watering slowly, deeply and less often.

Newly planted trees

A newly planted tree on clay soils (typically found in Oakville north of the QEW) with a diameter of six cm (2.4 inches) will need about 45 litres (10 gallons) of water every 10 to 14 days. Take the amount of rainfall and lawn irrigation schedules into account when planning your watering schedule, and check the Halton Region website for water restriction information.

Trees on sandy soils (typically found in Oakville south of the QEW) need twice as much water as trees on clay soils, and should be watered every five to seven days. Apply water slowly into a berm of mulch spread at the edge of the planting hole. Move the mulch berm out as the tree grows.

Mulch

Mulch wide, not deep (a two-four inch layer is ideal).  More than four inches may cause problems with oxygen and water levels.

Allow for a one-two inch mulch-free area around the trunk of a tree. Mulch packed up against the trunk of the tree can case the tree to rot at the base.

Agreement for contractors to perform Arboricultural Services on town property

If at the owner's expense, an owner wishes to have a contractor perform town-approved maintenance on a town-owned tree, or tree planting adjacent to the owner's property, the owner is required to submit a completed Agreement for Contractors to Perform Aboricultural Services on Town Property (pdf, 91 kB).
