If you want to grow your own veges on the cheap, one of the easiest ways to save money is to save seeds. I've written a few posts about seed saving and growing from seeds, see them here.
my seed collection
Seeds that I have to swap
Poor man's beans
Green beans (climbing) - "Blue Lake"
Yellow beans (bush) - "Cherokee Wax"
Spring Onions (see explanation here)
Green peas - "Lacey Lady"
Parsley - flat leaf
Lettuce (not sure what its called, like a cos type)
Silver beet (chard) - "heritage"
pea seeds ready to harvest
Seeds that I 'need'
Turnips, swedes, radishes (advanced seed saving!)
All other beans and peas
If you'd like to swap, send me an email with the seeds you want (eight.acres.liz at gmail.com). I might run out of some of them, but I'll try to send you what I can.
If you don't have any seeds to swap, start saving and send me something later, I don't mind sending some seeds to help you get started with your garden. Or let me know what else you have to swap instead, last year someone offered me old copies of Grass Roots and Earth Garden!
I can only swap within Australia (and I can't send to Tas or WA), but if you are in another country and have something to swap, leave a comment to see who else is out there. If you have a seed swap post to share, leave a comment too.
