Organic mulching: what it is and why it protects the soil
on Oct 31 2026
In nature, the soil is never left bare: leaves, twigs, and plant debris constantly cover it, protecting it day after day. Mulching simply imitates this principle. In the dry garden, it thus becomes a valuable tool: it helps retain moisture, limits weeds, and protects the soil over time.
Bare soil is exposed soil
Bare soil is vulnerable soil, exposed without defenses to all the elements. The sun heats and dries it out, the wind dries its surface, and driving rain compacts it, washing away its top layer. Each element, taken alone, seems insignificant. Together and repeated over time, they make the soil increasingly difficult to manage.
Under these conditions, each irrigation lasts for less and less time. Water evaporates before it can be absorbed deep down. The result is a vicious cycle: you irrigate more, but the soil retains less.
You only need to look at a forest to understand the strategy nature adopts. The soil is always covered by a layer of leaves and plant material that protects it from the sun, wind, and driving rain. No one laid it out on purpose: it is the spontaneous result of a natural balance. Mulching is born precisely from imitating this mechanism.
What is Multispecies Organic Mulch
Our Multispecies Organic Mulch is made up of over twenty organic Mediterranean plant species. It is not just shredded wood, as is often imagined when talking about mulch. It is a rich mix of leaves, twigs, and various plant parts, replicating the variety of cover found in nature.
It is precisely this variety that makes the difference. A Mediterranean forest is not covered by a single type of material, but by many different elements that complement each other. Our mulch is inspired by the same principle: a multispecies composition that creates a more complete cover than traditional mulches.
It is spread in a layer of several centimeters on the soil surface and forms a protective cover that works silently, day after day. It requires no special interventions: once spread, it continuously performs its function, protecting the soil.
The benefits, season after season
The mulch layer protects the soil from direct sunlight, acting as a screen between the soil surface and solar radiation. Thus, the soil remains cooler and moister on the surface, and evaporation is reduced. This benefit translates concretely into a significant reduction in the irrigation required.
At the same time, the mulch limits weed growth: by covering the soil, it deprives them of the light they need to germinate. Fewer weeds mean less time spent on maintenance.
Finally, by protecting the surface from temperature fluctuations and driving rain, it helps maintain its structure more stably over time. It is a simple act that, like the entire dry philosophy, works with nature instead of against it, drawing inspiration from what nature itself has always done.
