Step 1

Prune purple passion flower vines heavily in the fall or early spring to remove dead leaves and wood. Trim it back to healthy stems, leaving some nodes or buds in place to encourage strong growth in the spring.

Step 2

Cut back strong stems by at least 1/3 of their length. This will keep it under control and prevent it from growing out of hand.

Step 3

Remove the vines that are not following the desired pattern and those that are too stringy looking. Make the cuts on a diagonal slant. The more you cut back passion flower, the bushier it'll grow the next season.

Shorten passion flower vines by propagating new plants from the old one. Cut off sections that are 4 to 6 inches long, while the plant is actively growing.
