Box is an incredibly versatile plant that is perfect for trimming into topiary shapes, including balls, spirals and much more.
The best time to trim box topiary is late spring. This will encourage the development of side shoots.
These new shoots can then be cut in midsummer to create a well-defined surface in whatever shape you wish.
This will again cause sideshoots to grow – the plants can be given a final shaping and tidy up if necessary in early autumn.
Always use sharp tools to shape topiary – this will mean that stems are cut cleanly, not crushed.
Here’s how to trim box topiary.
For complex topiary shapes, it’s easier to make the shape out of chicken wire and secure it over the box plant. As soon as the growth pokes through the mesh of wires, clip into shape.
