I purchase most of the seeds I plant from the following seed companies:
www.rareseeds.comwww.gurneys.com (I only purchase my Early Contender Bush Beans) from Gurney's. These green beans are the best I've ever eaten!
Once we establish a good crop, we allow a plant or two to go to seed, so we can save our seed for the next planting season.
We've been successful in saving several pepper seeds along with many varity of tomato seeds. This will be our first Spring using our own tomato and pepper saved seeds we've planted for this Spring's garden...
