Proven successful substrate for tree nurseries
Thanks to our many years of experience in the tree nursery sector, we are able to offer every grower, crop or cultivation situation a suitable substrate and we can rely on formulas that have more than proven themselves in practice. Our reference substrate serves as a basis for new applications and can be used for all different segments within the tree nursery, such as avenue trees, Skimmia, Ellwooodii, shrubs, p9 seedlings, Hydrangea, Rhododendron, Prunus, Conifers, Conica and Pinus Juniprus. We also have various substrates in our range for gutter cultivation and pot-printed crops. Due to our varied customer base and our practical experiences, we have a lot of knowledge and expertise of different types of companies; from propagation companies to propagation companies.
We consider our customers to be our partners. We consult and work together to achieve the very best results. The physical and chemical properties of the substrate are also carefully considered as well as the wishes and needs of the grower, the plant and the cultivation method. Logically these properties vary from substrate to substrate. We continually explore ways of adapting the substrate to boost its effectiveness.
Balanced cultivation
Each type of crop is different and requires a specific blend of raw materials that support growth and result in successful yields.
A selection of the main raw materials used by Lensli in the tree nursery segment are:
- Swedish sphagnum peat. This ensures properties including a good moisture balance.
- Rice husk. This considerably aerates the structure of peat-rich substrates. It ensures good root development, resulting in strong and resilient plants.
- Hortifibre. This wood fibre gives the substrate a more open structure, with good air permeability to encourage strong root development.
- Basis BioMix. This efficient raw material has the right biological composition to promote resilient; robust crops.
- Bark. This is a stable material that is not susceptible to shrinkage. It contributes stability to the structure of substrates.
Benefits and properties
The main properties of our substrates for tree nurseries:
- Extensive knowledge of tree nurseries, our products and raw materials.
- Continuous product development and innovation.
- We offer good, high-quality alternatives for peat.
- The physical and chemical properties of the substrate are also carefully considered as well as the wishes and needs of the grower, the plant and the cultivation method.
- Stable and homogeneous substrates that ensure constant, guaranteed quality and delivery.
- Suitable for year-round cultivation.
- Our substrates help growers increase their sustainability and achieve the smallest possible footprint. The more sustainable raw materials are used, the smaller the footprint.

- Available in various types of packaging. Choose from: Bulk, big bales, big bags and 45L bags.
Insight into sustainability and eco-footprint
The themes of sustainability and environmentally-conscious cultivation are gaining traction throughout the horticultural sector. To support growers in this transition, all our substrates are categorised into a sustainability class. This class gives our customers continuous insight into the sustainability and circularity of a substrate and the corresponding properties. This classification system not only aims to offer CO2 and peat-free substrates, it also examines the origin and type of organic raw materials and fertilisers.
Four different classes are used: A, B, C and D. The sustainability class of a substrate is determined based on a set of pre-defined standards. By taking these criteria into account when formulating a substrate blend, we can produce a product with the desired sustainability class.
The table below shows the different classes and the applicable criteria ranging from the peat percentage to increasing use of circular raw materials.
A Class
- 100% Peat free
- At least 50% green raw materials
- Maximum 35% mineral raw materials
- No inorganic fertilizers
CO2 Footprint Class A
(<60kg eq/ENm3)
B Class
- 100% Peat free
- At least 15% green raw materials
- Maximum 35% mineral raw materials
CO2 Footprint Class B
(<60kg eq/ENm3)
C Class
- Maximum 65% peat
- Exclusively RPP peat
CO2 Footprint Class C
(50-150kg eq/ENm3)
D Class
- More than 65% peat (unlimited)
- Exclusively RPP peat
CO2 Footprint Class D
(70-350kg eq/ENm3)
