Mandevilla Vine

Zone Garland, TX zone 8 | Paula Laughery added on February 11, 2017 | Answered

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? Paula.

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.
