My third resolution from 2010 was "I will save heirloom seeds from my annuals, perennials, vegetables, fruits, and herbs. I will use these seeds next year and I will trade them with other gardeners so that I can get new varieties."
I saved seeds from my tomato plants. I saved enough that I was able to send 100+ packets of seeds to a seed exchange. This year, I will save other seeds, too.
