5. Cultivation in Quebec

The giant sequoia can be interesting as an exceptional ornamental tree, but its cultivation in Quebec carries risks.

• Choose a very sunny location, protected from drying winds.

• Avoid constantly waterlogged soils.

• Water regularly during establishment.

• Protect young plants from extreme winter conditions.

• Check the hardiness of the plant with a local nursery before purchase.

  The giant sequoia can withstand some intense cold, but the duration of frost, winter winds, and soil conditions influence its survival.

To remember : the giant sequoia is mainly remarkable for its volume, longevity and massive trunk. It should not be confused with the coast redwood, which holds the height record among trees.
