How to Stop Periwinkle From Spreading

Periwinkle (Vincor minor) is an evergreen ground cover, growing about 6 inches tall and blooms in the spring and early summer. It spreads rapidly and is known to invade lawns and other areas of the landscape. Most periwinkle plants get out of control if it is not controlled. Fortunately, with a few practices, you can stop periwinkle from spreading and enjoy its colorful flowers and green foliage in its intended space.

Instructions

- 1
  Wait until the early spring, after the last frost of the season, but before the periwinkles begin to grow again.
- 2
  Mow, trim or cut back periwinkle down to about 4 inches every two to three years at this time. This will help keep it contained and from spreading.
- 3
  Install a garden edge into the soil where you don't want the periwinkle to spread. Plastic lawn edging that is inserted several inches into the soil works well.
- 4
  Remove periwinkle growing outside of its bounds manually by digging or pulling it out. You can also use a garden rake or hoe to remove it. Remove it again if it grows back.
