Garden topiary: how to shape a shrub

Topiary is the art of clipping trees and shrubs into shapes. Green balls, cones, spirals and even animals turn an ordinary garden into a formal one. You can make your first topiary yourself: the key is choosing the right plant, starting with a simple shape and clipping regularly.

A little history

Shaped plants were known in ancient Rome, and topiary flourished in the 17th century, the age of formal gardens such as Versailles. At Levens Hall in England, topiary planted in the late 17th century survives to this day.

Which plants to use

• Box — the classic for small shapes, with tiny leaves and a dense crown. In recent years, however, the invasive box tree moth has badly damaged box in Ukraine, so check plants regularly.
• Yew — tolerates clipping and shade and suits large shapes; every part except the berry flesh is poisonous.
• Privet, hornbeam, thuja — faster-growing, good for large shapes and hedges.
• Japanese holly — a box alternative with similar small leaves.

How to clip a shape

• Choose a plant with a dense, evenly leafy crown.
• Start simple — a ball or a cone. For a cone, set three canes around the plant tied at the top and clip along them.
• Clip gradually, removing a little at a time and stepping back to check symmetry.
• Repeat 2–3 times a season: box and yew are usually clipped in late spring or early summer and again in late summer. Avoid clipping in hot weather or shortly before frosts.
• Feed in spring — the plant needs energy for new growth after clipping.

The frame method

For complex shapes — animals, birds, letters — a wire frame is used. Either place it over a young shrub and gradually clip the plant to the outline, or fill it with moss and compost and plant it with ivy or ground-cover plants. The second option works even on a terrace and gives quicker results.

For low-effort garden ideas see Low-maintenance garden, and for conifers that take clipping see Conifers for the garden.

FAQ

How long does it take to grow a shape?

A simple box ball can be shaped in 2–3 seasons; large and complex figures take several years.

What can replace box?

Japanese holly, yew, privet or dwarf thuja cultivars — depending on the size of the shape and the light.
