we've got it in a large box at the moment, been in there for five years now and doing great! this years flowers were the most impressive its ever put out! however- its getting a bit thick around the middle so to speak and looking at it im finding it nearly impossible to find a starting place. I get the whole "pruning group 2/thinning it out" thing, but im curious about just how far to take it. its got 5 main stems coming out of the soil, one of them is the original stem that sprouted 5 years ago. its nearly 1/2 of an inch thick. im thinking about removing this one main stem to free up some space and thin it out overall. I thought I would use the same logic as when pruning a hydrangea. remove the older stems, thin it out, promote new shoots at the base? however im not sure if that logic necessarily applies to clematis vines... thoughts?
