Topiary Spirals are an elegant addition to any garden. They are formal, showy plants which are shaped from small trees or shrubs. Topiary plants are relatively easy to care for but do need regular pruning to maintain a neat and tidy shape. Often, topiary is kept potted so will require regular watering, a high quality topiary fertiliser and good compost. Using a specialist topiary fertiliser will reduce excess growth so less pruning is needed. The pruning of topiary is relatively easy, simply trim off any protruding branches using sharp shears. To maintain the spiral shape cut the top level of the spiral as the tree grows. Match the angle of the level below it and gradually turn it over one or two seasons as the plant grows
