I planted 3 types of tomatoes 30 days ago (San Marzano, Roma & Large Cherry)
I would like to transplant them at the end of this month. My concern is that
they aren't growing, at least not like they should. I've attached a link to
a small picture (http://web.syr.edu/~jhbass/images/tomatoes.jpg). Shouldn't
my plants be at least a little bigger ? Are they big enough to transplant
yet ?

-many thanks
James
