A thought for some of the North American permies on the forum... and the rest of us!
I have stumbled onto a group of forums called "Garden Web". There are over 50 different forums grouped together, and include a permaculture forum, companion plants, organics, etc as well as forums on individual plants.
There are forums for world regions, and a permie one for North America so they may have a few better ideas about how to deal with long winter conditions!
For the rest of us the other forums will provide some useful info, although it'll be a matter of picking and choosing advice between those that like their chemical warfare and those that enjoy a more subtle approach.
Make sure you don't leave us for them though!
The world does not need more rootless symbolic analysts. It needs instead hundreds of thousands of young people with the skills, intellectual depth and moral stamina to rebuild neighbourhoods, towns and communities around the planet.
