I did 2 varieties today... Mountain Princess and Bush Beefsteak, 4 seeds each. I still want to do some Romas - my luck they will all germinate... I have room for 4 plants on the side of my house... 3 really, but i cram in 4.
Thankfully - my neighbor, who's dog pees on all my plants - they are moving... So i wont have to worry about the Maters... plus i can probably add more "out back" . Maybe one year, i can even do more of a 'garden' not just tomato plants willy nilly in my flower beds.
