The last Saturday of January is National Seed Swap day in the US. Search google for a seed swap near you and get ready to make some trades. If you are in Canada or Britain you can also search for Seedy Sundays. Local seed trading is the best, because you can find seeds from plants that are well acclimated to your climate. If you can’t find a seed swap near you, there are many great online seed trading venues.
If you would like to get started saving seeds to swap but aren’t sure how, check out the website How to Save Seeds. It has a great handbook which covers individual vegetable seeds. You can also check out this archived Webinar from Seed Savers.org on how to save seeds.
