I am so sorry to post this question as I am sure it has been answered so many times, but please bear with me. I searched the seed saving forum first and read through several pages...couldn't find it and the search function isn't working!!! So, I have a couple of heirloom tomatoes I want seeds from for next season, mostly Mr. Stripey...how do you save seeds and when...are the seeds ready when the tomato is or do I need to leave a couple on the vine longer just to seed??? Again, so sorry to have to ask this!! But all help is so appreciated!!
