Let her go! If its only one plant just chop when u get back...unless ur in the north then I think frost is around the bend, like another 2-3 weeks. So jus watch the weather maybe check out an almanac for the frost day. Fuck, if ur an experimentalist like me and there was frost coming to your area before u will be back I'd throw one of those frost protective sheets over it..those mesh like ones, on the day u leave tho
Goodluck
