There is no easy way to get rid of this or any other invasive plant.
Periwinkle will produce new plants when part of a stem contacts the ground, so be aware of this if you cut this invader. Do not compost it--bag it before trashing it.
If you want to avoid chemicals and the labor of pulling and digging this plant out, here is an option you might try.
Start by mowing it close to the ground.
Cover that area with multiple layers of cardboard--overlapping the edges at least 6 inches (15 cm).
The cardboard should extend far beyond the area of growth to ensure no light reaches the plants.
Soak the cardboard with water. Cover with 6 or more inches of mulch and soak the mulch to compact it.
Watch for any new growth and remove it as it appears.
It could take several seasons for this to take effect. ... See MoreSee Less

First day of Spring
It’s the first day of spring in the Northern Hemisphere! Our seasons are caused by a tilt in Earth’s orbit, so for half of the year, one hemisphere gets more daylight than the other — known as summer.
Twice a year, the Northern & Southern Hemispheres get equal amounts of daylight — these days are known as equinoxes.
Happy spring, Northern Hemisphere!
