- ✅ Shipping across Europe
- ✅ ISPM 15 treatment available
- ✅ Our own sawmill in Galicia
Decorative mulch and bark are the finishing layer that protects soil, holds moisture and suppresses weeds in gardens, flower beds, nurseries and public green spaces. At Maderas Caamaño we produce this material as a direct by-product of milling Galician pine and eucalyptus at our yard in Berdoias, Vimianzo, in the province of A Coruña: bark and off-cuts are shredded, screened by particle size and graded into several fractions, from a fine mulch suited to ornamental beds through to coarser bark intended for paths and shaded areas.
Our buyers range from garden centres and nurseries purchasing bagged mulch for retail resale to landscape contractors, municipal parks departments and civil works companies that need bulk volume for a specific project. A number of civil engineering clients also use shredded bark as a temporary ground cover on slopes and embankments, where it acts as a physical barrier against surface run-off while permanent vegetation establishes itself. Order sizes across this customer base range from a handful of pallets for a small nursery to full-truck bulk loads for a multi-hectare park renovation, and we size each dispatch to the project rather than pushing a single standard load size on every buyer.
As a family-run sawmill with a long-standing presence in Galician forestry, we fold mulch and bark into a wider range of biomass by-products — wood chips, firewood and pellets — that come off the same production line, which lets us offer steadier availability and combine several product lines on one shipment. We supply customers across Spain and export to garden-centre and landscaping distributors in other European countries, with full or part-truck deliveries and supply terms (EXW, FOB or delivered) agreed case by case according to volume and destination.

From the sawmill to the garden: how our mulch and bark are made
Mulch is not manufactured from raw materials bought in for the purpose — it starts life as bark and off-cuts generated while we saw pine and eucalyptus logs into timber. Rather than treating it as waste, we route it through a shredding and screening line that sorts the material by particle size, in a process not unlike the one behind our wood chips for industrial biomass, though screened here for ornamental rather than energy use.
The result is several distinct particle-size fractions, so we can offer a fine mulch for delicate plantings alongside a coarser, longer-lasting bark for paths and slopes. We add no dyes or chemical treatments: the colour and texture are simply those of freshly processed Galician wood, and the tone darkens naturally with weathering over time.
Because mulch is a direct by-product of our own milling, output tracks the volume of logs coming through the yard each week, which lets us give indicative lead times of roughly one to three weeks for bagged orders, and somewhat longer for large bulk loads that need several days to accumulate. Customers working to a fixed project date are welcome to check current availability ahead of time, particularly around the spring and autumn planting seasons when demand tends to peak.
Raw material: bark and wood from Galician pine and eucalyptus
Galician pine, the dominant species in the forests around our yard, produces a fibrous, relatively light bark that breaks down gradually, which makes it well suited to a longer-lasting ground cover in beds and hedgerows. Eucalyptus, also common in the region, yields a somewhat denser bark that we often blend with pine to fine-tune the weight and breakdown rate of the finished mulch for a given use.
We do not mix bark with construction waste or with chemically treated wood: the material comes exclusively from logs brought into the sawmill for conversion into boards and beams, giving buyers a straightforward origin story to pass on to their own customers — something garden centres and municipal buyers with green-procurement criteria increasingly ask about.
The pine-to-eucalyptus ratio in any given batch shifts over the year with how much of each species we happen to be cutting, so colour and texture can vary slightly from one delivery to the next — normal for a natural product that isn't artificially standardised. For orders where a very uniform look matters across a large, visible area, we recommend requesting the full volume from a single batch wherever project size allows.
Quality and grading: screening and dimensional consistency
How useful a mulch turns out to be depends heavily on how consistent its particle size is within a given batch. We screen the material into separate fine, medium and coarse fractions before bagging or loading it in bulk, and we sort out longer splinters or off-type debris that can otherwise find their way in during the milling process.
This grading lets a nursery order a uniform fine mulch for ornamental plant trays and a municipality order coarse bark for a public park without either order competing for the same material. It also makes coverage-per-square-metre planning easier, since a consistent grade gives a more predictable layer depth than an unscreened mulch would.
As a rough guide for order planning, a 5–7 cm layer of fine mulch covers approximately 15–20 m² per cubic metre of material, while coarse bark settles at a lower density and so covers somewhat less at the same depth. We share this kind of estimate with landscapers and municipal buyers to help size an order before it's confirmed, though actual coverage always depends on the area and the compaction the customer is aiming for.
Before any batch is bagged or loaded, someone on the yard runs a visual check for oversized pieces, splinters or foreign debris that the screening line may have missed, particularly on orders destined for retail bags, where the bag is often the first thing a garden-centre customer inspects. Bulk loads for civil works or municipal projects go through the same screening stage but with a somewhat coarser tolerance, since the end use there tolerates more variation than a small ornamental bed does.
Applications by sector: landscaping, parks and erosion control
Decorative mulch and bark have a broad range of uses across sectors:
- Residential gardens and landscaping: covering beds, borders and lawn edges
- Nurseries and garden centres: bagged product for retail resale
- Municipal parks and public gardens: large-scale green-space maintenance
- Civil works and embankments: temporary ground cover for erosion and run-off control
- Playgrounds and recreational areas: a natural cushioning surface
- Urban allotments and organic growing: moisture retention and weed suppression
Many of these same customers — garden centres, distributors and grounds-maintenance contractors — also buy other biomass by-products from us to round out their range or their own fuel needs, such as our firewood and hardwood heat logs, which lets them combine product lines on a single order and make better use of the delivery.
Buying patterns differ quite a bit by sector: a nursery tends to place recurring orders of palletised bags to keep shelves stocked, a municipality typically concentrates its order into one or two bulk loads a year timed to the planting season, and a civil works contractor may need staggered deliveries over several months as a slope-stabilisation project progresses. We adjust the sales format — bag, bulk bag or loose bulk — to fit that kind of schedule wherever we can.
Sustainability and forestry sourcing
Mulch is, by nature, a circular-economy product: it puts to use bark and off-cuts that would otherwise have to be managed as sawmill waste. By directing this material to gardens and landscaping instead of landfill, we extend the useful life of every log we process and reduce demand for non-renewable ground-cover alternatives.
Our forestry activity draws on the traditional management of Galician woodland, following an approach broadly aligned with internationally recognised principles for sustainable forest management, of the kind promoted by bodies such as the FAO's forestry programme. We do not present mulch itself as an individually certified product, but its origin — locally sourced wood bark, free of additives — makes it a reasonable alternative to synthetic ground covers for buyers looking to reduce the environmental footprint of a landscaping project.
Beyond where the raw material comes from, mulch itself has a well-understood, positive effect on the soil it covers: as it breaks down slowly it adds organic matter, helps moderate soil temperature near the surface, and reduces how often beds need watering compared with bare soil, particularly relevant through the summer months in areas facing water restrictions. These are general agronomic benefits of mulch rather than a specific claim about our product, but they are worth factoring into the return on a landscaping or public-space renaturalisation project.
Export and logistics across Europe
Beyond the Spanish market, we supply mulch and bark to garden-centre and landscaping distributors elsewhere in Europe. Loads can go out as full-truck bulk bags or loose bulk, or palletised bags for distributors who resell in retail units; in either case we adjust the moisture content at loading to keep dead weight down on longer hauls.
Export paperwork is prepared in the relevant languages for the destination country, and delivery terms (EXW, FOB or delivered) are agreed order by order depending on volume and route. Working with a forestry by-product like this fits the growing interest among European distributors in suppliers who can point to a traceable, responsibly sourced timber origin — an area where organisations such as PEFC help set the frame of reference for the sector, though each buyer should check the specific certification requirements of the market they sell into.
Bulk bags travel well over longer distances because they keep the material contained and stackable, which matters once a load crosses two or three borders on its way to a distribution yard; palletised bags suit distributors who break a delivery down into smaller retail-ready units on arrival. For either format we factor typical transit times into the lead time we quote, so a customer ordering for a specific planting window knows roughly when to expect the load rather than being given a single fixed date that may not hold across a long-haul route.
For distributors who also handle biomass fuels, we can combine a mulch shipment with wood pellets for biomass heating on the same load, reducing the per-unit cost of transport.
Unlike wood pallets, bulk mulch does not require ISPM 15 heat treatment, since it is not solid wood packaging material, though we do recommend that importers outside the European Union, such as those in the United Kingdom or Switzerland, confirm the customs and phytosanitary requirements that apply to forestry by-products in their own country ahead of time, as these can vary by destination and by the type of packaging used. Within the EU, mulch moves under standard commercial paperwork, with no additional phytosanitary steps in most cases.

Frequently asked questions
What is the difference between fine mulch and coarse bark?
Fine mulch is graded to 0–15 mm and is typically used in beds and ornamental plant trays, while coarse bark (20–50 mm) is used on paths, embankments and shaded areas where a longer-lasting, better-draining cover is preferred.
How often does garden mulch need to be topped up?
It depends on exposure and grade, but as a general guide a well-applied layer usually holds its function for one to two seasons before the top layer needs partial replenishment.
Is bark mulch suitable for pots and planters?
Yes, the fine grade is commonly used in pots and planters, since it holds moisture without compacting the growing medium or restricting watering. Smaller containers usually do better with the finest of the grades we offer.
Can I buy mulch or bark in bulk for a municipal project?
Yes, we supply full or part-truck bulk loads for municipalities, grounds-maintenance contractors and landscaping companies, matched to whichever grade suits the intended use on the project.
Do you export decorative mulch and bark outside Spain?
Yes, we supply garden-centre and landscaping distributors in other European countries, as bulk bags, loose bulk or palletised bags, with delivery terms and paperwork agreed according to the destination country.
Is the mulch treated with any chemicals or dyes?
No, our mulch and bark are sold in their natural colour, with no added dyes or treatments; the reddish-brown tone of freshly processed wood darkens naturally over time with weathering.
What's your minimum order for decorative mulch & bark from galician pine and eucalyptus?
We don't publish a fixed minimum order for mulch — smaller bagged or bulk-bag quantities are available alongside full-truckload volumes for landscaping and garden-centre distributors. Tell us your target grade and volume for a quote.
