An established live boxwood topiary needs about an hour of attention per piece per year. Two cuts a year, a feed in March and another in October, plus water in the first two summers. Sellers rarely put a number on it. It is also the only kind of topiary that gets better every year.
Shaping a boxwood by hand. The whole job is two cuts a year, and when you cut matters more than how.
The work, in hours
A settled boxwood ball or cone in open ground wants two cuts a year: one in late spring once the first flush has hardened, one in late summer to tidy what followed. A spiral or a poodle takes longer per cut, because the shape has more edges to keep honest. It is still the same two visits.
Call it twenty minutes a cut on a ball, forty on a spiral. Add a feed in early March and again in October, five minutes each. Then walk past it every few weeks in the growing season, to catch pests before the damage shows.
So: roughly an hour a year on a simple shape, two on a complicated one, plus the feeds and an eye kept on it. You need to do that hour in the right weeks, and that is what catches people out.
When to cut matters more than how
Cut in late spring after the new growth has firmed, and again in late summer. Between those two cuts, leave it alone.
Never cut in winter. A boxwood cut into cold weather pushes soft growth it cannot harden, and that growth burns in the first cold wind. The damage shows in February, and gardeners blame the frost.
Never cut in the heat of the day in high summer either. The exposed cut ends scorch and the plant goes bronze at the surface. Cut early in the morning, on a cool day, with sharp blades.
A blunt blade crushes the stem instead of cutting it. The crushed end dies back a few millimetres. A whole surface of crushed ends gives a badly cut boxwood that brown haze a week later.
Water, and the two summers that decide it
In the first two summers, water the root ball itself deeply and check it with a finger rather than trusting a schedule. The soil around it can be damp while the ball at the centre is bone dry. That single failure looks exactly like disease and is not.
The roots are still spreading into the ground beyond the ball they arrived in, so the plant is drinking from a much smaller volume of soil than its size suggests. Once established in open ground, a boxwood is genuinely drought-tolerant and will look after itself in all but a severe year.
A pot is a harsher home than it looks, and the sums are different. We set them out properly in boxwood in a planter.
What goes wrong, and what it costs
Three things account for most of the losses we see.
Winter desiccation. Water deeply into late autumn, right up until the ground freezes. It costs nothing but the time and is the single cheapest thing you can do for a boxwood. An evergreen keeps losing water through its leaves all winter. A plant that went into December dry cannot replace what it loses, and the bronzing shows in late winter.
Blight. Real and serious, so understand it before you buy rather than after. The disease field guide covers identification and what to do. The short version: get the airflow right and keep water off the foliage, before any treatment.
The wrong cultivar in the wrong place. Check the cultivar tables in the zone-by-zone guide before you buy.
Published growth rates across common cultivars run from about half an inch a year to six. If you choose a fast cultivar where a slow one belongs, you will need to cut more often and take more off at each cut to hold the same shape for the life of the plant.
Live against artificial: which to buy
If you will enjoy holding the shears, buy live. A live piece costs less and needs the hour a year above. It is worth more every season as it thickens. An artificial piece costs more up front at the same size. It needs nothing at all, and it does not improve.
In a commercial forecourt where the grounds contract changes hands every two years, artificial is the honest answer and we will say so. The arguments are in the faux versus real comparison.
$155. A globe, 12 to 15 in tall, and it ships by parcel.
Quoted. A poodle: three heads, so three times the edges to keep.
Quoted. A cone at 18 to 24 in, quoted with delivery.
Buy the shape you want in three years, not the shape you want now. A boxwood grows into its form, and a piece bought slightly under-sized settles better than one bought over-sized and cut back hard to fit.
The live range, with sizes and root-ball measurements, is on the live boxwood category. Read the receiving FAQ before your delivery arrives rather than after; it takes five minutes.
Questions we get asked
How often does a boxwood topiary need cutting?
Twice a year. Once in late spring after the first flush has firmed, and once in late summer. A ball takes about twenty minutes a cut, a spiral about forty.
Can I cut it in winter?
No. A winter cut pushes soft growth the plant cannot harden, and that growth burns in the first cold wind. The damage shows in February and gets blamed on the frost.
How much water does it need?
Very little once it is established. In the first two summers, water the root ball deeply and check it with a finger. The soil around it can be damp while the ball is dry, and that failure looks exactly like disease.
Which cultivar should I buy?
The one whose growth rate matches how often you want to cut. Rates run from half an inch a year to six, so the cultivar you choose decides your workload for the life of the plant.
Is blight a reason not to buy live?
Not on its own. It is a real risk, and worth understanding before you buy. Airflow and keeping water off the foliage come before any spray.
