This will be our first year with a garden. I am quite excited. Right now I am experimenting with preparing our own seeds from real food! I bought every organic variety of tomato at the grocery store (Roma, slicing, small round, cherry). I also want to find some grape tomatoes and heirlooms....so we might have to buy some seeds.
I have never tried this before, but from what I have read, you can cut the tomatoes in half on the equator, squeeze out the juices and seeds, add some water, cover with plastic wrap, poke a small hole in the top, and let sit for several days removing the plastic once a day to stir the mixture (loosening all the seeds), and then drain and let completely dry out for several days. Then the seeds can be stored.
A fermentation process happens as you leave the seeds out, and this kills off any potential tomato diseases from ruining your seeds.
Soon we will plant our own starts and see what happens!
