Christmas Evergreen in Ontario: Plant Outside If Native Species

Key Question: What Species?

If it's a native evergreen (spruce, fir, pine), plant it outside now—dig hole 2× pot, backfill potting soil, mulch, water. It'll handle -40°C.

If it's a non-native (Norfolk Island pine, etc.), it's a houseplant—keep indoors.

Ask the selling nursery for species ID. Native = plant out. Non-native = keep in, cool & bright.
