Long grass: what it takes to bring an overgrown lawn back

By the Mowie crew · 31 Aug 2026 · 5 min read

Life happens. You went on holidays in October, it rained for three weekends straight, and now the back yard is somewhere between "meadow" and "lose a toddler in it". Every mower has seen worse, and no lawn is beyond saving - but it won't be fixed in one pass, and the first cut costs more than a normal mow. This is how it usually goes.

The rule of thirds

Grass stores its energy in the leaf. Cut away more than about a third of the blade in one go and the plant panics - it drops root growth and throws everything at regrowing leaf, which leaves it weak, brown and open to weeds. Take knee-high grass straight down to 30 mm and you're left with yellow straw and bare dirt.

So an overgrown lawn gets staged. High cut first - deck at maximum, sometimes a whipper snipper or brushcutter pass before the mower can even get in. Then a second cut a week or two later brings it down further, and by the third visit you're back to a normal mowing height with a lawn that's still alive.

What the first cut involves

  • Slow passes, often doubled. Long wet grass bogs mowers. Half-width passes at walking-slowly pace take two or three times as long as a maintained lawn.
  • An enormous amount of clippings. A lawn that's had three months of spring growth holds a trailer-load of material. It has to be raked, caught or carted, and if it can't go in your green bin, tip fees apply.
  • Surprises. Long grass hides dog toys, sprinkler heads, star pickets and, in a Melbourne summer, the odd snake. Mowers walk the yard first for a reason.
  • It'll look rough for a fortnight. The lawn under long grass has been growing in the dark. Expect pale, flattened, patchy - it greens up quickly once light gets back in.

What it costs

Around Melbourne, a first cut on an overgrown lawn runs 50-100% over the normal price for that size - so a lawn that would be a $90 regular mow might be $140-180 to bring back, occasionally more if it's waist-high. It costs more because it takes longer - no other reason. (Full price breakdown in what mowing costs in Melbourne.)

When you list an overgrown lawn on Mowie, say so honestly - there's a grass-length question on the listing for exactly this. Mowers can see the measured area and the photos, so the bids you get already account for the state of it. A mower who arrives expecting a jungle does a better job than one ambushed by it.

Keeping it from happening again

The cheapest lawn to mow is one that was mowed a fortnight ago. Regular bids come in 10-15% under one-off prices, and in the growing season fortnightly is the sweet spot for most Melbourne lawns - often the ongoing price lands close to what you were paying for occasional panic mows, minus the panic. Set the schedule once and it just happens; skip or pause any time from your phone.
