Jenny: Tomatoes even grow in sewer outlets, the seeds having been digested by us and then carried right through the sewage system. I would respectfully suggest, that you not get "mentally" hung up on soil pH. If you were growing large crops, yes, but for a home gardener, not necessary at all. Plant your "Early Girl" seeds now, outside, if you think the last cold weather has visited you. "Early Girl" incidentally, is a tomato seed developed for colder zones, like here in Canada. LOL. But True! The point being that they can be planted "early" and reach fruition before the snow flies. In your zone, I would certainly plant the seeds outside now. They don't care what soil they are in, BUT, they need fertilizer and water (but never overhead water)! I have grown them several times, and up here they get very, very big. Good luck! Just do it!
