I'm a member at Folia (button on the side bar) and I'm also the caretaker of the Gardening in Canada group there. One of our members is organizing a seed swap during the month of November.

You package up seeds from your garden and mail them off to the organizer. In turn you will receive the same number of packets of seeds back. So if you send in 10 packets you get 10 back. You can do whatever number suits you.
We are looking for some more Canadians to join in the swap. You have to live in Canada to participate as seeds are not supposed to be sent across the border due to some regulations that are in place. I know that many people exchange seeds between countries but this seed swap is just for Canadians.
Folia is a great place to organize your gardening online. You can keep track of your various gardens, plantings, seed stash and more.
If you would like to join the seed swap, pop over to Folia and join (it's really easy), find the Gardening in Canada group, and look for the message to join the swap.
Seed swapping is a great way to start a friendship garden with seeds from across our great country. If you are looking for seed info and some seed labels to print, click the Sow Then Grow tab at the top of my blog.
I'm looking forward to hearing from you telling me you would love to join our Canadian seed swap.
