I live in Zone 7 in Long Island and received a Mars Bare Root 1 year vine today which I had purchased online (they said they would ship at the appropraite time!!)
Anyway, it snowed here today, I am about a month from last frost and the tempsa re ranging from 30-40 daytime.

If I plant this guy, will he survive or does anyone have any recommendations, maybe covering the plant or even keeping it in the house with the roots in tissue for a couple of weeks and maybe the temps will hit 50?

Any advice is appreciated

I'd try keeping it in a cool, dark place with the roots wrapped in wet newspaper for two weeks, then pot it up, and do the 'outside during the day, inside at night' thing until tax day, or whenever the neighbor's vines start putting out leaves (I'll try and remember to post when my mom's start budding out)
