DUMONA produces a complete range of composts for red fruit soilless cultivation: strawberries, raspberries, blueberries, blackberries.


🏵 Strawberry



The composts for strawberries consist of blonde peat and composted maritime pine bark. The proportions and calibres are adjusted according to the producer’s irrigation constraints.

It is possible to incorporate fertilizers and biostimulants specifically adapted to strawberries.

We also offer coco growing bags, specially adapted to strawberry cultivation. Planting and drainage services on demand.


🏵 Raspberry and Blackberry



Our composts for raspberry and blackberry bushes are mainly composed of composted maritime pine bark (different granulometries to ensure optimal drainage).

We can, on demand, modify the formulas by incorporating peat, coco peat or coconut fibre. We also offer mulching discs adapted to different containers as well as “ready-to-plant” grow bags.


🏵 Blueberry


Our composts for blueberry bushes are composed of maritime pine bark and fractions of blonde peat to ensure drainage, aeration, and water retention. The pH is limited to 4.5 to meet the requirements of this crop.


🏵 Tray Plant


We offer special substrates based on fine coconut chips
(coco diamond) as well as specially selected blonde peat.
