I have a Mandevilla vine that has a lot of dead looking vines. Should I cut it back? The trellis is covered in dead growth but there are small shoots that are coming out too. The article said to cut it back 1/4 to 1/2″ per branch. Can I do way more to so it will come out with all new vines?

The plant in the pictures is actually a Clematis vine. These have different pruning requirements than Mandevilla, so see these articles for advice:
First, determine which pruning group your plant belongs to, according to what time of year it flowers. Then, follow the pruning procedures in the articles for that pruning group.
