Topiaries are made into a variety of shapes for in the home and in gardens by shaping and trimming ivy as it grows. Heart-shaped ivy has continued to be a common design, fitting easily into household pottery while using indoor ivy varieties. Make your own heart-shaped ivy topiary instead of spending a lot on a ready-made one.
Twist two ends of 18-gauge green floral wires together approximately 1 inch from the tips.
Bend and shape the wires into a heart shape using the twisted ends as the centre-top and the opposite ends as the centre bottom.
Twist the bottom ends together beginning about 3 inches from the tips.
Insert the wire heart into the centre of potted ivy's container. If the heart seems unstable, wrap a floral pick around the end and use to stake the wire more securely.
Cut several 3-inch pieces of 24-gauge cloth-covered floral wire. The cloth covering will keep the wire from harming the tender plant vines.
Select the longest vines of the plants and gently wrap them up each side of the wire heart. Secure them with a piece of cut wire when necessary by gently twisting the wire around the vine and heart 2 to 3 times. Do not over twist or bend the vines to prevent breakage of the vine.
Keep the plant watered and in proper light for it grow, filling out the heart as the vines become fuller and longer.
Use an artificial ivy plant by placing floral foam into the chosen container. Cover the foam with moss and insert the artificial plant into the foam. Use a glue gun to secure the plant's stem if does not want to stay in place in the foam.
