Jared, since I don't have experience gardening your particular area, it's hard to say -- but that sounds pretty early to me and I would lean more toward the later date suggested on the calendar, which I think is April 7 or something like that. The best thing would be if you could ask someone locally -- again, maybe the County Extension people
I really loved "The Martian" ! (maybe because it makes gardening where I live look easy
)
