Did you know your backyard could hold the key to a greener, healthier Markham? Through the City of Markham’s partnership with LEAF, property owners can access additional discounts to grow their own piece of the urban forest – making tree planting more affordable and impactful than ever.
a professionally designed native plant garden
Designing a garden with native plants doesn’t have to mean choosing between ecology and beauty. With a few foundational garden design principles, you can create a space that supports wildlife while feeling cohesive, inviting and distinctly your own. Whether you’re planting a pollinator patch or reimagining your whole yard, good design can help guide the eye, offer structure, and even bring a touch of whimsy—creating a garden that feels good and functions well.
