Have also just planted a grape, but dont know what to do with it now, it is growing quite happily at the moment but I dont want to kill it off or anything, ANY info would be most welcom by a grape beginer !!!
Happy is good! Mostly leave it alone, but watch for drying out. Water deeply but infrequently (the definition of "infrequent" depends on your soil and the weather). You can let it just wilt, but then soak it well. Ralph
