Urban greening in Canada

Vertical gardens for cold-climate balconies and walls

Rialinta gathers field notes on building living walls, planting balconies and layering green roofs across Canadian cities, where freeze-thaw cycles and short summers shape every decision.

Three ways to add green to a tight urban site

Most Canadian apartments and rowhouses have little ground to work with. The approaches below stack planting vertically or overhead instead of outward.

Balcony systems

Railing planters, modular pockets and trellises that hold up to wind exposure on upper floors and pack down for winter.

Living walls

Facade-mounted panels and felt pockets, with attention to drainage, weight and how cladding behaves through freeze-thaw cycles.

Green roofs

Shallow extensive layers for sheds and low courtyards, built around sedum and hardy perennials that tolerate exposure.
