Master Gardeners and University Extension Service resources are very different in Canada vs the USA. In Canada, two universities offer courses for master gardeners who then volunteer with Master Gardeners of Ontario, independent of any ongoing university involvement. In the USA, extension services retain connections to their universities and contribute to and have access to a wealth of online materials offered on their websites.

Master Gardener University Extension Resources – tips and links

Master Gardeners in Ontario have websites and FaceBook groups and increasingly are offering online materials. Each group is at a different stage so you’ll find that some sites offer more than others.

University Extension services in the USA are excellent sources of free information for agricultural uses and home gardens and their information is often geared to the same zones as we encounter in our Ontario gardens. Their materials are usually science-based and peer-reviewed.

University Extension Services (USA)

  • to find better quality advice from University Extension services, add this to your search string site:.edu 
  • links to Extension Services across the US. When possible, use information from a more northerly one as their climate and growing conditions are likely to be more similar.
