hi, javaMom!
Swaps are easy!
Just come to the right place at the right time, & bring your extra plants, seeds, garden art/tools/books/magazines/anything that has anything to do with gardening.
People have brought rocks, compost, & rusted scrap iron (to make art!).
You can go to the link below & post the things you have & ask for the things you'd like to have.

I notice you asked for irises & daylilies on your other post:
My dear, I have *bunches* of irises, & I'll bring you a big box of them!
Mine are all historic irises that have been around for a long time; they aren't fancy, but they're very healthy & they reproduce well!
I look forward to meeting you!
