Overwintering a Potted Rhododendron in Cold Climates: Survival Assessment and Care

Rhododendron Left Outdoors in Pot (Ontario, Zone 5)

Rhododendrons are hardy to zone 5 in ground. In a pot, roots freeze, often killing the plant.

Scratch bark: green = alive. If alive, plant in ground immediately in acidic, well-drained soil, mulch heavily.

Future: always plant in ground or protect pot in unheated garage.
