I planted Pinetree Garden's Manyel tomato on February 25th and they are now producing beautiful tomatoes in my Nashville, Tennessee garden.( It is August 7th today). The packet of seeds I used to plant these wonderful tomatoes was dated 2012 - five years old. I kept the seeds in an old tin can along with a packet of silica gel to absorb moisture (not in the freezer). These look like a keeper so far and I expect I'll plant them again next year. I enjoy growing German (i.e. Mennonite and Amish), Native American and Russian varieties for the fun of it. I learned how to grow tomatoes from my grandfather who had a truck garden in Boaz, Alabama and am very thankful for him.
