How to Prune Vinca Vine
- 1). Mow the vinca vine with a rotary lawn mower to control its vigorous spread.
- 2). Prune the stems back to 4 inches in height every few years to get rid of old growth and rejuvenate the vine.
- 3). Pull rooting stems from the ground, bringing the roots out with them. Cut them to keep the vine from spreading. Discard them in the trash or they may root elsewhere in the yard.
