I live in Ottawa Ontario . I would like to remove 32 feet old dying hedges between two driveways ( separating my property with my neighbour ) and replace it with either Eastern white cedar hedges or Emerald Green Arborvitae ( Smaragd) ? The location gets plenty of sun and late day shade . Which one would be best to plant ? What is the cost difference between the two ? When would it be best to plant the new cedars ?
Thanks for contacting the Toronto Master Gardeners about which type of ‘cedar’ would be best for using for a hedge in Ottawa. We get many questions and inquiries about this issue–please see the attachments below.
Even though the Emerald Green Arborvitae ‘Smaragd’ seems to be available in Ottawa [see here] , growing them may be a challenge unless they are grown and sourced locally. The Eastern white cedar would be more adaptable to the Ottawa climate.
Cost-wise, there seems to be a big difference–the ‘Smaragd’ option would most likely be much more costly–you’ll have to determine what’s best for you.
The best time to plant would be in the fall before the ground freezes. Please see the links which will give you more comprehensive advice–you can then decide what’s best for you.
Good luck with replacing your dying hedges.
