Gardening for green areas

The global concern at the environmental level is based on water savings.
In this sense, the use of pine bark in outdoor spaces can contribute substantially to reduce the current level of irrigation.

In pursuit of this strategy, we have developed a product with adequate characteristics for coverage that guarantees the permanence of moisture in the soil for a longer period, as it avoids evaporation of water.

This bark for soil conditioner is a shell with high level of dedusting, properly sanitized and with 100% of purity.

The main advantage in its use is to hinder the growth of weeds and contribute to the maintenance of soil moisture, reducing the frequency of irrigation. In addition to these technical reasons, we would like to highlight its beauty.

Professional Market

Our professional pine bark is mostly intented for professional horticulture.
Is widely used as raw material for orchid as part of a component in mixtures for instance in outdoor or cultivation of tree nursery stock.

maritime pine bark for orchids


This is a sustainable product of reliable and consistent quality that guarantees high performance.

This bark consists of a very low amount of elements like manganese. The process mainly involves the removal of cambium and weeds.

As a result, we have a bark of 100% purity. 

pot covering


Advantages using as Pot covering:

- Keep moisture content in the pot decreasing the irrigation frequency (saving water);

- Makes difficult the development of weeds reducing maintenance and conservation costs;

- Values decorative aspect.



We seek to monitor the development of trends in t he agricultural sector on the world stag e and in this way we see a steady growth in the production of red fruits.

We are developing, together with an RHP accredited international organization, a suitable substrate for this culture with a high quality standard.

For the RHP certification for bark as raw material for substrates, our company is inspected concerning:

  • Incoming raw material
  • Steaming process by unique RHP Bacillus test
  • Hygiene of the company
  • Transport
  • Registrations

For the RHP certification for bark as raw material for substrates, the products of Alfarroxo are very frequently analysed by an external laboratory concerning:

  • EC, pH and nutrients
  • Nitrogen fixation
  • Heavy metals
  • Purity
  • Screening
  • Organic matter
  • Weeds
  • Nematodes
  • Human pathogens
  • Unique growing trail for Orchids

For comparison, we present the advantages of using pine bark in comparison with other alternatives, eg: spagnum moss


  • Is organic
  • Is physical stable (not too soft)
  • Can keep a bit of water but not too much


  • Uncomplicated
  • Practically inert
  • pH neutral


  • Is steam sterilized so free of pathogens

Justification why pine bark does not need to be composted

  • It has already the right physical properties. When you compost bark there is a change that the air capacity is getting to low
  • Composting to make it phytosanitairy clean is not necessary it is steamed (from origin the bark of the Pinus pinaster hardly carries illnesses).

Generically speaking, our proefssional pine bark is mostly for orchid substrate and horticulture.

The regular and periodical control of the physical, chemical and phytossanitary parameters assure an unique quality and add maximum value to your potting soil mixtures with Alfarroxo Trading products.

This is our business that our customers appreciate:

  • It’s organic additive and very uniform
  • Improving the structure
  • Reliable process and availability
  • Renewable resource
  • Sustainable process
  • Delivery in time

After processing various fractions remain from fine to coarse. the goal is to achive 100% purity bark.

Fractioned bark holds less or more water depending on the fraction. The coarse fractions are used in professional orchid growers and are very “airy”.

The air content increase strongly depends on the fraction distribution of the bark. The bark is a hard and phisicaly stable material so it brings stability to structures of mixtures.

The best mixture is air content 40% to 45% and GBW (water in substrate) similar with 10% to 13%. The balance between these to factors results in an excelent orchid substrate.

Fraction 09/12 mm

With this fraction there will be a better drainage and higher air porosity. This fraction has greater stability.

Fraction 13/18 mm

Traditionally this is the most common fraction within the orchid growers because it assures a homogenous substract and it’s easier to mix with other products improving the structure. This fraction is mostly used to increase air content.
