On sand that drains in minutes, this is the single most useful thing you can do to a garden. It holds water in, keeps weeds out, and makes every visit after it shorter.
Rough square metres, or just describe it — we’ll work it out.
Left is true of any garden. Right is what Pāpāmoa’s ground does to the maths.
Weed seed needs light to get going. A proper layer denies it that, which is why mulching does more for weed control than weeding does.
Warm, open, free-draining, full sun. A bed cleared and left bare here is back to weeds within weeks, which is why we would rather mulch your beds than keep charging you to weed them.
Mulch slows evaporation from the surface, so what you water or what falls actually stays where the roots are.
Pāpāmoa is coastal dune sand — it drains in minutes. A bare bed here is dry again within a day. Mulch is the difference between watering constantly and barely watering at all.
Around 75 to 100mm. A thin dusting looks tidy for a fortnight and does nothing at all, because light still reaches the soil.
Fine bark gets picked up and moved by onshore wind, and washes off any slope. We use chunkier grades here that knit together and stay where they are put.
Mulch piled against a trunk traps moisture on bark that is not built for it, and the plant rots at the collar. Leave a clear gap.
Under bark on a slope or a path edge it earns its place. In a planted bed you intend to keep adding to, it becomes a nuisance within a few years — and we will say so rather than sell you more of it.
If we are already doing your mowing or garden visits, this goes on the same day and there is no separate call-out in it.
It is easy to spend real money on this and get almost nothing for it. Here is where that happens.
Half a day on a standard set of Pāpāmoa beds, longer if they need a proper weed first.
At the root, including kikuyu runners. Mulch over living weeds just delays them.
A clean edge is what stops mulch migrating onto the lawn and back again.
Slopes and path edges yes. Planted beds you’ll keep adding to, usually no.
75–100mm, spread evenly, with a clear collar around every stem.
Paths and drive cleared, then a photo through when it’s done.
Get these right and mulch works for years. Get either wrong and you have wasted the money.
Priced by the cubic metre laid, including the weeding beforehand.
A cubic metre covers roughly 10 to 13 square metres at the right depth. Most standard Pāpāmoa front gardens take one to two. Beds that need a serious weed first are quoted separately.
Get your actual numberThis one reduces what you pay us afterwards, and that is the point. On sand a bare bed is a weed nursery, and if we are doing your garden visits you are paying for that weeding every single time. A proper layer cuts it roughly in half from the next visit onward. It is the rare job that pays for itself on your own invoice.
Two good windows, and one where you get less for the same money.
Autumn is the pick, spring a close second. Mulching in autumn means the beds hold moisture through the following summer and weeds never get their spring start. Doing it in January still helps, but you have already paid for the watering and the weeding you were trying to avoid — you get less for the same spend.
They kept telling me the beds needed mulching and I kept putting it off. Did it last autumn and my garden visits have genuinely halved in time since. Cost me once and saves me every fortnight.
The ones that come up on nearly every Pāpāmoa garden we quote.
Around 75 to 100mm. This is the thing people get wrong most often — a 25mm dusting looks tidy for a fortnight and does almost nothing, because light still reaches the soil and weed seed germinates straight through it. If you are going to spend the money at all, spend it on the right depth. Half a bed done properly beats a whole garden done thinly.
Roughly one cubic metre for every 10 to 13 square metres of bed at the right depth. Most standard Pāpāmoa front gardens take one to two cubic metres. We measure it up when quoting rather than guessing, because ordering short means a second delivery fee for the sake of half a metre.
Sometimes, and often not. Under bark on a slope or along a path edge it genuinely helps hold everything in place. In a planted bed you intend to keep adding to, it becomes a real nuisance within a few years — you end up cutting through it every time you plant something, and it eventually works its way to the surface. We will tell you which situation you have rather than selling you more of it.
It stops most of them, and it makes the rest far easier to pull. Weed seed needs light and mulch denies it that. What still happens is seed landing on top of the mulch and germinating in it — but those come out with two fingers rather than a trowel, because they are rooted in loose material rather than compacted soil.
Something chunky. Fine bark gets picked up by onshore wind and washes off any slope, which on an exposed Pāpāmoa section means you are replacing it far sooner than you should be. Chunkier nugget grades and arborist chip knit together and stay put. Chip also breaks down into the sand over time, which is genuinely useful on ground that holds so little organic matter.
No, and this matters. Mulch piled against a trunk or stem traps moisture on bark that is not built to stay wet, and the plant rots at the collar. We leave a clear gap around everything. It is a small detail that kills a surprising number of shrubs.
Every two to three years on most Pāpāmoa beds, sooner on exposed sections where the wind moves it. Bark and chip break down into the soil over time, which is a good thing rather than a fault — it is how sandy ground slowly gains the organic matter it needs. A top-up is far cheaper than the original job.
Mulching usually gets booked alongside one of these.
