How to Get Rid of Wild Sweet Potato Vines in Your Garden


Wild sweet potato vines thrive as produce in a garden and in the wild, with invasive drought-resistant vines that grow up to 30 feet long. These vines bloom big purple and white flowers in spring season that can be up to 6 inches wide. Since sweet potatoes can grow in almost any condition or type of soil, it is almost classified as a weed. If you want to get rid of these vines, it will take some time and manual labor, but it can be done.

Step 1

Determine the location of all the existing wild sweet potato vines. Follow the vines to find where they end and where the bulk of the plant begins.

Step 2

Use the pruning shears or scissors (depending on how thick the vine is) to cut the vine off 1 inch from the ground.

Step 3

Sprinkle a handful of salt on the cut area.

Step 4

Apply the herbicide the remaining bulk section of the vine until it is soaking wet. Continue to apply the herbicide around the plant area in the soil, about 5 inches from the base of the sweet potato vine.

Step 5

Discard the cut-off vine pieces into the trash.

Step 6

Examine the cut vine stubs in the ground to see if they have died a week later. If it looks like the vines have started to grow again or look alive, cut them off again and apply the salt and herbicide a second time.
