Are you in the USA or a US territory? Have you heard of the NIFA land grant university website? No? GASP!
If you're in the USA or a US territory you can actuality use this helpful map to find the land grant colleges in your area that work to provide free classes, information, and sometimes even seeds to locals.
For example I picked a random state, Iowa, they have three sites listed and one is for http://www.extension.iastate.edu/ offering free classes, local news on ordinances affecting those who are trying to work for conservation, and some workshops.
I hope all our US gardeners and food growers find something useful here!
