Tree Care

Markham trees are pruned on an ongoing block pruning program. Trees deemed by Markham arborists as a "hazard" are pruned or removed immediately.

What Can You Do to Help Care for Markham's Trees

Help keep our trees green. Trees need water to grow.

On your outdoor watering days, remember to water the young trees in your yard and on your boulevard.

Review Markham’s Summer Water Restrictions Bylaw for more information.

With your help, new trees will grow to beautify our neighborhoods and will increase Markham’s tree canopy. Review some watering Dos and Don’ts for more information [PDF]

Six ways you can help Markham Trees:

Water them during periods of drought.
Be careful not to damage roots and do not attach anything to the tree
Do not place edging or construct walls around the base
Do not mound soil around the base of trees
Place a 5 to 8 cm deep layer of organic mulch around the base of trees, which helps retain moisture in the root zone and prevents root damage. Mulching can also help promote better tree growth.
Be careful not to damage the trunks of trees with your mower or weed trimmer
A little extra care will go a long way.

Trees in New Developments

Trees planned for new developments and parklands are coordinated through the City.

The Trees for Tomorrow Streetscape Manual [PDF] is a significant resource tool for developers, contractors, residents and staff. It outlines design and technical guidelines, and identifies selected tree species suitable for new developments.

Natural Areas

Trees and all other vegetation within natural areas contribute to the natural ecosystem. Forested areas including the underbush and fallen trees decay naturally, and provide organic material and protection to the forest floor. They also provide a natural habitat and environment for animals, birds and insects. Unless there is a danger to the public, natural areas are left undisturbed. We encourage the community to adopt these areas and help to keep them clean of garbage.
