You are in a zone 3 which means it's colder area(-37C to -34C) and you experience a shorter season.

Thanks so much :)

Canadian garden zone map .. find your location, zoom in, and get your zone

Here is a link that might be useful: Canadian garden zone map

radovan - you'd be in zone 6 which is -23 C to -20 C.

However you should also be aware of microclimates. Depending on your surroundings, you could have areas within your own yard that could be colder or warmer. So observation is key. For example, a plant bed near a brick wall, in a south facing yard, may be a zone warmer. or if it's located in a shadowy location, or location that is unprotected and windy, then it might be a zone colder. And a trick to keeping borderline hardy plants healthy is to mulch them well during winter.

thank you all. it looks like i am in a quite cold zone?
i do experience problems blooming my hydrangeas if they are not covered, himrod grape vine too although Concord grape vines are OK.

Thanks again, now I know my zone:-)

Hi I am going to Edmonton next week and my son wants me to do some gardening with him. I don't know when the safe time is for planting annuals there, does anyone know?

zwoddle, Ontario goes by Victoria day for planting. It's probably different in your zone. I suggest checking the Northern gardening forums for advise. Or you can simply take your cues from your local garden centres.

May 24 is the traditional planting weekend (against the advice of garden centres). Many years the traditional re-planting is done the following weekend.
