If you’ve got leylandii, you already know the situation. You turn your back for one summer and suddenly you’re staring at a wall of green that’s taken on a life of its own. These things grow fast. We’re talking 60 to 90 centimetres a year under decent conditions, which is brilliant when you want privacy and genuinely alarming when you forget to book a gardener.
I get asked about leylandii trimming costs more than almost anything else. So here’s everything you actually need to know, with real numbers.
What Does Leylandii Trimming Cost on Average?
In the US, expect to pay $200 to $800 for a standard leylandii trim on a residential property. In the UK, most homeowners pay £150 to £500. In Australia, budget A$250 to A$700, and in New Zealand, NZ$280 to NZ$750.
Why the range? Because leylandii pricing swings more than most hedges. The variables that move the needle the most are height, length, and how long it’s been since the last cut.
Why Leylandii Costs More Than Other Hedges
Let’s be honest: leylandii is not a fun hedge to trim. It’s dense, it grows fast, and once it gets above about 10 feet (3 metres), you’re looking at work that requires proper ladders or even a cherry picker for anything serious.
Here’s what drives costs up specifically with this species:
Height. Leylandii frequently reaches 15 to 20 feet on residential properties before owners call in a pro. At that height, a trimmer can’t just stand on the ground with an extendable cutter. You need scaffolding, a tower, or a cherry picker, and the hire cost for that equipment alone can add $100 to $300 to the job.
Density. The foliage on leylandii is thick. A trimmer is working against serious resistance, and the sheer volume of clippings produced on a 30-foot run of tall leylandii can fill multiple large waste bags. Debris removal fees of $30 to $75 are common on bigger jobs.
Speed of regrowth. Because leylandii grows so fast, a hedge that was trimmed 18 months ago can look genuinely out of control. The more overgrown it is, the longer the job takes, and most professionals charge by the hour ($40 to $90 in the US, £30 to £70 in the UK).
Leylandii Cost by Size: A Quick Reference
| Hedge Size | US Estimate | UK Estimate | AUS Estimate |
|---|---|---|---|
| Small (under 6 ft / 1.8 m, up to 20 ft long) | $150 to $300 | £100 to £200 | A$200 to A$350 |
| Medium (up to 12 ft / 3.6 m, up to 40 ft long) | $300 to $550 | £220 to £380 | A$380 to A$550 |
| Large (over 12 ft / 3.6 m, or long run) | $550 to $1,000+ | £380 to £650+ | A$600 to A$1,000+ |
These are ballpark figures based on a reasonably maintained hedge. If yours hasn’t been touched in three or four years, add at least 30 to 50 percent.
How Often Should You Trim Leylandii?
At least twice a year. Once in late spring (May to June) and again in late summer (August to September). Some people get away with one annual trim if they’re disciplined and cut hard, but two trims keeps costs per visit lower because the job stays manageable.
Here’s the maths that surprises people: one proper trim per year at $500 often costs more per visit than two trims at $280 each. Overgrown leylandii takes much longer to cut, so you actually save money by trimming more frequently.
One Thing You Cannot Do With Leylandii
You cannot cut back into old brown wood. Unlike many other hedging plants, leylandii will not regenerate from bare brown stems. Once you cut past the green, that section stays brown forever. This matters a lot when you’re thinking about height reduction, because you can only take off what was added in the last season or two from the sides. The top is different and can be dropped, but the sides have limits.
If you’re dealing with a leylandii that has genuinely got out of hand, it’s worth having an honest conversation with a professional about whether renovation is even possible, or whether removal and replanting makes more financial sense long-term.
Tips to Keep Your Costs Down
- Book in spring before peak season demand pushes availability tight
- Ask whether your gardener does recurring visits at a discount (many do, typically 10 to 15 percent off)
- Clear access before they arrive. Moving bikes, bins and garden furniture costs you nothing but saves them time
- Trim in late summer when demand is lower than peak spring season
- Combine with other garden work to reduce minimum call-out fees
