Tips for getting to grips with topiary

Put your artistic talent to the test and transform your garden with some simple topiary...
If you’ve visited stately homes and gardens this summer and admired the beautifully clipped mazes, evergreen spheres and cones and other statuesque shapes, you may be inspired to create your own topiary.
This art of training plants into intricate shapes and forms may seem an occupation for the extremely skilled and artistic gardener, but there are a few tricks of the topiary trade that make the process easier than it may appear.
Start with simple shapes
Balls, pyramids, cones and obelisks are among the easiest shapes to start with, according to the RHS. Choose a young, well-proportioned plant such as box or yew, which can be tightly clipped for detailed work. They are slow-growing, so once their shape is established it should be fairly easy to maintain. You can also use holly, privet and the evergreen honeysuckle Lonicera nitida.
Wire frames are widely available to create the shape you want and flexible young shoots can be tied into the frame to create bushy growth. Sideshoots can be cut regularly back to two or three buds to encourage branching. When the plant is growing, make sure the ties aren’t cutting into the stems. Stems facing downwards will grow the slowest and need to be tied in regularly, while vertical growth is the quickest.
Larger statues need open sites
Individual specimens can be grown in pots, but if you are after something bigger they will be more likely to succeed in an open sunny site, sheltered from strong winds.
As both box and yew are slow-growing, they only need trimming twice a year once their shape is established, in early summer and early autumn, using sheep shears or single-handed clippers.
If you are starting from scratch, choose a plant that already has the makings of a shape, such as a dome or spire, so all you have to do is exaggerate it.
Common ivy can easily be trained into formal shapes with, say, the help of sweet pea rings, to grow around metal hoops or arches against a wall. Dwarf conifers can also be used to make effective architectural shapes, while upright varieties are ideal for training into obelisks or spires. Common holly can be used to make into mushroom or sphere shapes.
Create a lollipop
To make a standard box bush, when the plant is around 2ft high gradually shorten the lower branches by half so a stem forms and shape the top into a rough ball shape. A year later, cut all branches from the stem. The lollipop top should be half the stem height and you can then trim it to shape.
As the plant matures, the branches and leaves should become tightly knitted to give a solid appearance. Apply an annual dressing of Growmore and mulch the soil with organic matter in spring.
Shape a sphere
To make a topiary sphere, stand above the plant and clip a broad band around its waist. Clip from the top middle point to the waist, then upwards from the bottom middle point to the waist. That will give you the outline for your sphere.
These sort of shapes look great in pairs outside front doors to make an impressive entrance, or add structure when put together on a patio.
If you want to make a pyramid or cone, tie three canes together into an extended triangle to use almost as a guideline for shape, tying any long shoots to the cane with twine to form the outer edges and prune the plants to the pyramid template.
Use frames for complex shapes
With other shapes, place a wire ‘former’ over the plant and only start clipping once the plant has grown through. Formers, unlike frames, can be removed once the outline of the shape has developed. Use frames of sturdy wire to help with more complex shapes such as spirals, cake stands, arches and animals.
Potted topiary needs watering thoroughly and regularly in summer and the roots need protection from frost in the winter.
Once you have got the hang of the sphere or the pyramid, who knows, before long you may be able to create that grand peacock you’ve been dreaming about.
