Treat your lawn.

Professional lawn treatment in the UK — feeding, weed control, scarifying, aerating and overseeding — typically costs £200–£600 per year for a typical suburban lawn, spread across 4-6 visits through the growing season. A one-off renovation of a tired lawn (scarify + aerate + overseed) ranges from £200–£500; ongoing treatment programmes work out cheaper per visit.

This is different from mowing — lawn treatment focuses on the health and appearance of the grass itself. Companies like GreenThumb, TruGreen, LawnMaster offer national packages; local independent specialists are usually 20-30% cheaper.

The standard 4-treatment annual programme

1. Spring (March-April) — feed and weed (selective herbicide + fertiliser). Triggers active growth and kills overwintering broadleaf weeds.
2. Early summer (June) — feed only. Slow-release nitrogen for sustained growth into summer.
3. Late summer (August) — feed and weed (if weeds returned).
4. Autumn (October-November) — autumn feed (low-nitrogen, high-potash) to harden the lawn for winter resilience.

Programme cost £250-£550 per year for a typical UK suburban lawn (100-300 m²).

Typical UK lawn treatment costs

Scarifying — the most-skipped treatment

Thatch (dead grass and moss between green blades and soil) builds up over time, creating a spongy mat that prevents water and nutrients reaching the roots. Scarifying mechanically removes thatch using a powered raker.

Best done in autumn (September-October) when grass recovers fastest. The lawn looks dreadful for 2-4 weeks afterwards, then comes back stronger and denser. £100-£300 per scarify; once a year is often enough for active lawns.

Aerating

Compacted soil (from foot traffic, mowing, kids playing) prevents oxygen, water and nutrients reaching grass roots. Aeration creates holes in the lawn surface to relieve compaction.

• Spike aeration — solid spikes pushed in. Quick, cheap, mild benefit.
• Hollow-tine aeration — removes plugs of soil. More effective for compacted ground, particularly when followed by top-dressing.

£100-£250 per aerate; once a year for actively used lawns, every 2-3 years for less-trodden lawns.

Overseeding and top-dressing

Overseeding spreads new grass seed onto the existing lawn to thicken thin areas and introduce hardier varieties. Best done after scarifying and aerating, when seed-to-soil contact is maximised. £80-£200.

Top-dressing applies a thin layer of sandy loam to level minor undulations and improve drainage. £100-£300. Only needed for lawns with clear surface unevenness or drainage problems.

Things people often miss

• Lawn improvement takes 1-2 years — a tired lawn won't transform from one programme. Year one establishes the baseline and treats weeds; year two shows real improvement; year three the lawn is consistently good.
• Mowing matters as much as treatment — over-mowing (too short) and infrequent mowing both damage the lawn. Standard guidance: never remove more than a third of the blade in one cut.
• Watering after treatment — many fertilisers need watering in within 24-48 hours to activate and avoid scorch. If the forecast is dry, sprinkle.
• Pet-safe products — many lawn treatments are safe once dry, but wet treatments are toxic to pets and children. Confirm "ready for play" times with the technician.
• Moss is a symptom, not a problem — moss thrives in compacted, shaded, poorly-drained lawns. Treating moss with iron sulphate kills the moss, but the moss returns unless underlying conditions are addressed.
• Annual programme provider switching — most national providers (GreenThumb, etc.) lock you into 12-month contracts. Read the cancellation terms before committing.

Frequently asked questions

Want a local pro to handle this? A specialist lawn treatment service (independent local or national chain like GreenThumb / TruGreen) delivers consistent results year-round. Worth a 12-month commitment to see real change; one-off treatments rarely transform a lawn alone.
