White spruce (Picea glauca) is a coniferous evergreen native to the United States and Canada. The compact conical shape and short blue-green needles make white spruce a popular choice. The waxy needles have a waxy white coating (hence the name glauca, which means shimmering), and are quite sharp. As a plus, this is likely to deter dogs from chewing the tree.

White spruce is an important commercial tree in Canada, primarily grown for pulpwood.


White spruce can grow indoors or in the garden, making a great windbreak and providing a habitat for birds. Grow in full sun to part shade and fertilise every 2 – 3 months during the active growing season.

Christmas tree safety

While white spruce is non-toxic, care must be taken in homes with pets.

  • Always switch off and unplug Christmas lights when you are not around to supervise your pet.
  • Secure the tree to a wall using fishing wire to prevent it from being knocked over.
  • Do not place edible decorations on the tree.
  • Avoid the use of angel hair tinsel, the long threads can cause telescoping of the intestines if ingested.
  • Be careful with water preservers which are toxic to dogs. If you do use them, ensure that the water dish is properly covered to stop dogs from drinking from it.
  • Place breakable decorations high on the tree and non-breakables at the bottom.
  • Do not use decorations or lights which use button batteries which are deadly if ingested. Button batteries are not only a choking hazard but can burn a hole in the esophagus by isothermic hydrolysis.
