I planted the vine only last summer. It formed a decent 'clump' and climbed about 4 feet before winter set in. At the time of planting, I didn't do any research about pruning. (My bad!) So it was left 'as is' over the winter.

Now, the 'clump' looks nice and green and the leaves on the vining tendrils, which have grown another three feet, are brownish as would be old growth. Should I have pruned it around the time when I pruned my roses earlier last month to encourage new healthy growth? Or have I missed my window of opportunity and just leave it be for this season?

When is the proper time to prune it? Thanks for any info on this vine.
