After the plant has matured and the main stem has turned woody the stake may be removed. Some topiary forms are s imple wire outlines of circles or whimsical animals and objects. A topiary ring is a good example. These topiary frames are used with a vining plant, usually in a container. The wire form is placed into the pot as close to the base of the main stem of the vine as possible.
Some forms have prongs at the bottom which can be inserted into the soil.
The plant stems are twisted around the wire and tied onto the framework as they grow. Any unwanted side shoots may be clipped off as they appear. To train topiaries over a hollow wire form, you will first need to purchase a pre-made form or make your own. A topiary form may be made from a medium to heavy gauge wire which has been bent into a framework and then covered with chicken wire formed into the final desired shape. Depending on how you are going to train the plant, the form may or may not be filled with sheet moss and soil.
