How to keep your street trees healthy
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:
How much water does my tree need?
You can encourage a tree’s roots to grow deep to protect it from drought by watering slowly, deeply and less often.
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 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.
Mature trees on clay soils need about seven litres (1.6 gallons) of water for every centimetre (0.4 inch) of tree diameter (measured at breast height––1.3 metres [4.5 feet] above the ground).
To learn more about when, where and how long to water your tree, review this Texas Forest Services video.
If you notice a municipal tree is damaged or diseased, please contact the Urban Forestry section at the number or email at the bottom of this page.
The Town of Oakville prunes trees on municipal properties only. If you notice newly planted trees that require attention (eg. have broken stakes), please contact the Urban Forestry section at the number or email at the bottom of the page.
Residents may have the opportunity to hire a contractor to perform town-approved maintenance on a town-owned tree at the resident’s expense. Residents must submit a completed "Agreement for Contractors to Perform Arboricultural Services on Town Property," and receive approval from the Urban Forestry section before any work can be done on a tree. To learn more, open the agreement for contractors to perform aboricultural services on town property (pdf, 91 kB).
You are permitted to prune your private tree under the Private Tree Protection By-law provided the pruning meets good arboricultural standards, which include ensuring that no more than one-third of the live branches or limbs of a tree are cut in one season. A qualified tree expert should always be retained to carry out tree pruning.
The act of pruning trees on neighbouring private property affects private property rights and is a civil issue between private property owners. The town has no jurisdiction with respect to such issues. Therefore, it is best for property owners to come to an agreement between themselves with respect to trees overhanging property lines. If an agreement cannot be reached, you may want to consult a lawyer to determine your legal rights.
If pruning branches from your neighbour’s tree that overhang your property, please remember:
Oakville Hydro has hired the town's Urban Forestry section to conduct regularly scheduled tree maintenance to create the necessary clearances between hydro wires and nearby trees. Visit the Oakville Hydro site to find out which neighbourhoods will be affected, and to see examples of the types of trees that require pruning.
Town forestry maintenance crews prune and remove trees in woodlands throughout the town when necessary to protect the safety of people or property, or to promote forest health. All limb and trunk wood is left on site within the wooded area, according to practices endorsed by the International Society of Arboriculture (ISA). This encourages the natural regeneration of the woodland by providing biomass material for regrowth, provides habitat for woodland insects and animals, and leaves the sensitive woodland understory undisturbed.
Other woodlot maintenance action may include managing pests and diseases, invasive vegetation control, and prescribed burns to promote seedling and vegetation regeneration. Learn more about the March 22, 2012 prescribed burn at Iroquois Shoreline Wood carried out by Forestry staff.
The Central Hardwood Forest Conference is a series of biennial meetings dedicated to the sustainability and improvement of the Central Hardwood forest ecosystems. The objective of the conference is to bring together forest managers and scientists to discuss research and issues concerning the ecology and management of forests in the Central Hardwood region. Oakville is in the northern fringe of the Central Hardwood Region and has benefitted greatly from interactions with professionals that attend these meetings. The paper, Managing an Oak Decline Crises in Oakville, Ontario: Lessons Learned (pdf, 1.5MB), was presented at the 18th Central Hardwoods Conference in Morgantown, West Virginia in 2013.
