i have ordered 4 Amadeus climbers, how should i grow these, i'm new to rose vines. should i let one large trunk grow strait up and let the cains grow off of that like a grape vine or should trim the trunk really low and take the cains and let them grow up. also it is a zone 5 plant and i'm in zone 4a. dont know if that make any difference in how i let it grow so it easy to over winter? what will be the best way to over winter, i have heard of the tipping the roots method and the other is to grow in a buried plant bucket so it can be lifted out and removed to the garage and wrapped in plastic. i really have no idea so i thought i would ask early so i can prepare
