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 Matua gardens often have beds that have gone bare or thin over the years, which means the soil underneath is doing more work than it should. 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.
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.
Matua runs from sheltered inland gardens to open ground along Beach Road.
Matua’s inland gardens tend to hold moisture and mulch well under established tree cover, so top-ups are often less frequent. Closer to Beach Road and the saltmarsh, wind off Tauranga Harbour dries and shifts lighter mulch faster, which changes both the material choice and how often beds need topping up.
We pick the material to suit the site, not a single default. A fine mulch that looks great inland can end up scattered across a harbour-facing lawn within a season.
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 — beds near the wind-exposed harbour frontage benefit most, since they dry out fastest without it.
Our garden beds had gone almost bare in places and the weeds were constant. They topped up the mulch properly, thick enough this time, and put weed mat under the worst bed. Six months on and the difference in weeding time alone has been worth it, even being fairly exposed to the wind off the harbour.
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.
Yes. Wind exposure dries and shifts mulch faster near the harbour, so we often recommend a coarser material and thicker coverage.
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.
