traditional topiary frames method of planting calls
for using a frame as a guide. Some shapes
such as the bear, have a center ring.
As the shrub grows up through the ring,
it should be tied at various places
to hold it in place. By trimming it
to about 1/2 inch outside the frame,
the plant will be encouraged to grow
thicker and eventually fill the frame.
Frames with four legs, such as the deer, make it possible for a plant, such as a cypress, to grow up each leg. The plant then can be trained to fill the body and the head. Vines also can be used on these frames by tying them in various places and training the vines in to all areas of the frame.
