So where ELSE can you find accurate gardening information these days? Below, our suggestions for other, non-video sources.
On the Web
Google: Try using the search term site:.edu to find answers from universities. For example, for compost info you could put site:.edu compost in the Google box. Or add the school of your choice to find their specific info on the topic. (E.g., compost site:wmd.edu.)
To find actual research papers, use Google Scholar – because that’s what it serves up. Not for anyone looking for a quick answer.
Search Cooperative Extension Universities: Extension Search allows you to search hundreds of Cooperative Extension sites, which are land-grant universities charged with educating the public about gardening (among other things). Because not all Extension websites will give you the same answer on every topic, it’s best to visit more than one, and look for information that’s been published in the last five years or so.
