Microclimates may cover large areas or just a couple square feet

A guide for different microclimates and climatic zones

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.
