Grapevine topiaries can be whimsical additions to your home or landscape. Dried or fresh grapevines are decorative choices for covering different sizes and shapes of topiary forms. You can make small grapevine topiaries as centerpieces for your next event. You can also place large grapevine topiaries on both sides of your front entryway or create one as a focal point in your garden. Craft and floral supply stores offer dried grapevines, grapevine balls and topiary forms.
Soak the dried grapevines in water overnight. Dried grapevine rolls are available in most craft stores. If you are using fresh grapevines to make the topiary, it is not necessary to soak the vines.
Spray-paint a white foam topiary cone in a color that blends with the grapevines. The foam form will be mostly covered with moss and grapevines; a dark background color will blend in with the materials. Allow the paint to dry.
Cut floral foam to fit inside a decorative planter, to 1/2 inch below the rim. The planter should be at least 8 inches in diameter to visually balance the grapevine ball at the top of the topiary. Place the floral foam inside the planter.
Attach the base of the topiary cone to the top of the floral foam with hot glue.
Stretch out the softened grapevines. Attach one end to the base of the floral cone with floral pins. Don't worry if the pins stand out against the dark grapevines, you can cover them with sphagnum moss.
Wrap the grapevine around the topiary form; insert floral pins every 4 to 6 inches to hold the grapevine to the foam. Cover the foam with the grapevine. Cut the grapevine at the top with pruning shears.
Glue the grapevine ball to the top of the topiary cone with hot glue. Glue sphagnum moss to the grapevine topiary to cover visible floral pins and to add interest to the design.
