spring greetings to all! I want to grow roma tomatoes for canning
this year. I've planted heirlooms for salads before, but never
"sauce" tomatoes. Are there any recommendations for a nice, sweet,
prolific type? We'd prefer to start from seed, but if there's a great
seedling from garden centers or mail order, that's fine too! All
suggestions & opinions greatly appreciated! TIA, bobdrob
