Love this thread as someone that just planted some muscadines! I got Black Beauty and Lane.
I intend to grow them straight up onto a pergola (see thread here for more info), anybody have advice how to prune them now that I planted them. I presume I need to remove all but one branch (the longest one) and keep pinching off side-growth until I get to the height I want? Should I do that now while they are dormant or wait until they start breaking dormancy?
