Climate Zones

In general, the climate zone determines what will grow in your area. Zones are largely based upon temperature ranges and humidity, but do take into account other geographic and seasonal factors. A simple definition is by minimum temperature.

Microclimates are pockets that differ significantly from an area's overall climatic zone. They can be created by features that modify climate such as protected spots, exposed areas, elevation, and north/south facing slopes, walls and canyons.

Microclimates allow you to grow plants that would not normally grow in your area. Ask garden centre staff how to protect plants that may be marginal in your zone.
