When you imagine a huge cluster of grapevines, one image that may come to mind is Dionysus, who was portrayed as the little man in a toga that clutched a wine goblet in one hand and a bunch of grapes in the other. The imagery may actually be appropriate, because some wild species of grapes can move into your garden uninvited and turn it into their own personal Bacchanalia. Getting rid of unwanted grape vines can be as difficult as getting rid of an unwanted party guest.
Watch your garden carefully for sprouted grape vines. Grape vines can look like green shoelaces: sinewy, slender green cords that spring from the ground. Older plants are woody in texture. All vines climb by wrapping ribbon-like tendrils from the vine around support structures. If allowed to leaf out, the leaves will alternate on the sides of the vine, and appear deeply lobed with serrated edges. Vine seed is prone to being spread through by birds, and vines typically pop up among stands of trees, where they can find both shelter and support to grow.
Pull grape vine seedlings whenever they sprout by grasping the base of the springy vines and yanking with a backward, jerking motion.
Cut vines perpendicular to the ground at the soil line using garden shears before fruit has the chance to ripen.
Place all cut grape vines in a trash bag to contain ripened fruit.
Apply a systemic herbicide such as glysophate to the cut stubs of the vines to kill out the roots of the plant. Apply systemic herbicide according to package directions.
