Too thin and it doesn’t suppress weeds or hold moisture. Too thick and it can smother plant roots and starve the soil of air.

A good layer of mulch does three jobs at once — it holds moisture in, keeps weeds from germinating, and finishes a garden bed off properly. Established Ōhauiti gardens near the shops often have beds that have gone bare or thin over the years, while new landscaping on the hillside subdivisions needs its first-ever layer of mulch to get established beds off to a proper start, sometimes on a slope where it needs a bit of help staying put. We prep, lay, and top up to the depth that actually does the job.
A rough bed size and whether you want weed mat helps us quote accurately.
Depth and material matter more than most people expect.
Too thin and it doesn’t suppress weeds or hold moisture. Too thick and it can smother plant roots and starve the soil of air.
Coarse bark, fine mulch and compost-based products all behave differently for moisture retention, weed suppression and appearance — and hold differently on a slope.
Mat under mulch is excellent for new, low-maintenance beds, but it can get in the way of established plants that are meant to spread.
A thin layer of the best bark still won’t suppress weeds properly.
Mulch works by blocking the light weed seeds need to germinate and by slowing moisture loss from the soil beneath. Both of those only really kick in past a certain depth.
A thin, patchy layer looks tidy on the day it’s laid but does very little of the actual job — weeds punch straight through it within weeks.
Around 75mm is the sweet spot for most garden beds. Deep enough to properly suppress weeds and hold moisture, without piling material up against plant stems or smothering shallow roots.
Existing beds often just need topping up rather than a full re-lay — checking the current depth first avoids paying for a full job when a top-up will do.
Prepped beds, correct depth, finished edges.
Existing beds are checked first — a top-up is a different job to a full re-lay, and it’s priced differently too.
Beds are weeded before mulch goes down, not after. Mulching over existing weeds just buys them a head start once they push through.
Ōhauiti runs from a settled, flatter core to sections still being built out on the hill.
An established garden near Ohauiti Road usually needs an existing mulch layer topped up or refreshed, checked for depth before anything new goes down. New landscaping on a hillside section is a first-time job — freshly planted beds with bare soil in between that need mulch and often weed mat laid from scratch to get moisture retention and weed suppression working from day one. On sloped beds we lay it heavier at the base and edge it properly so a hard rain doesn’t wash it straight down the bank.
We scope the job to the bed’s history and its grade, not a single default. A first-time lay on a sloped hillside section is a bigger job than a top-up on a flat established bed of the same size.
Fixed once we’ve looked. Green waste and GST are both already in it.
We check existing mulch depth before quoting a full lay. A top-up costs a lot less than starting from bare soil, and plenty of beds only need the former.
Best laid before the growing season locks moisture needs in.
Spring mulch does the most work. Laid before summer heat sets in, it holds moisture through the driest months — new landscaping on freshly turned hillside soil benefits most, since bare, sloped beds dry out and erode fastest without it.
We landscaped the section after the build and had a row of bare garden beds on a slope with nothing on them. They laid weed mat and mulch properly across the lot, edged it so it wouldn’t wash down the bank, and six months on the weeding time alone has made it worth it.
Mostly about the job rather than about us, which is how it should be.
Around 75mm is ideal for most beds — enough to block light and hold moisture without smothering plants.
It helps in low-maintenance or new beds, but isn’t always right for established plants that spread naturally.
Roughly every six to twelve months, depending on material and how exposed the bed is.
Yes, every price we give includes GST.
A first-time mulch lay with weed mat and proper edging to hold it in place gets weed suppression and moisture retention working from day one without it washing down the bank.
We’ll recommend bark, fine mulch or compost-based product depending on the bed and its exposure.
Properly laid mulch at the right depth is low-risk — piling it against stems or walls is what tends to cause issues.
Yes, that’s covered under garden maintenance if you don’t need fresh mulch laid.
Most people add one or two of these, since we’re already on the property.
