Van der Knaap Peat Free Nursery Stock 70L is a professional peat-free growing medium developed for container-grown nursery stock. Designed to provide the root-zone structure and water management required by longer-term container crops, it offers commercial growers a professional substrate for peat-free nursery production.
Nursery stock places very different demands on a growing medium compared with short-cycle crops. Plants may remain in their containers for extended periods, making reliable structure, drainage, moisture management and root-zone aeration particularly important.
Van der Knaap's Nursery Stock formulation provides an open, well-structured and free-draining growing environment designed to support strong root development and healthy plant growth throughout the production cycle.
Supplied in 70L bags with 39 bags per pallet, it is suited to professional nurseries, commercial growers, landscapers and other horticultural businesses moving towards peat-free container production.
Why choose Van der Knaap Peat Free Nursery Stock?
- 100% peat-free growing medium - a professional substrate for growers moving away from conventional peat-based production.
- Developed for nursery stock - designed around the requirements of container-grown nursery plants.

- Effective water management - combines moisture availability with a free-draining structure.

Developed for professional nursery stock production
Container-grown nursery stock requires a substrate capable of performing over a longer production period. As roots develop and the crop increases in size, the physical characteristics of the growing medium become increasingly important.
An appropriate nursery substrate needs to provide sufficient moisture for the crop while retaining enough air-filled space around the root system and allowing excess irrigation water to drain.
Van der Knaap Peat Free Nursery Stock is formulated around these requirements, providing a structured root-zone environment for professional container production.
Professional peat-free growing media
Replacing peat in professional growing media involves considerably more than substituting one raw material for another. Different renewable materials have different physical, chemical and water-holding characteristics, which can change how a crop needs to be irrigated and fed.
Van der Knaap actively researches renewable and circular substrate materials and evaluates how changes in growing media affect crop performance. This includes assessing physical and chemical characteristics and carrying out practical cultivation trials.
The result is a professional approach to peat-free growing media that considers both the composition of the substrate and how that substrate performs within a real horticultural production system.
Root-zone structure & water management
Water and air compete for pore space within every growing medium. A substrate that remains excessively wet can restrict root-zone aeration, while one that dries too quickly can make maintaining consistent moisture difficult.
The open, free-draining structure of Van der Knaap Peat Free Nursery Stock is designed to provide an effective balance for container-grown plants, supporting root development while allowing growers to manage irrigation according to crop demand.
As with any professional peat-free substrate, irrigation should be based on the actual moisture condition within the container rather than simply following a watering programme developed for a previous peat-based growing medium.
Suitable applications
Van der Knaap Peat Free Nursery Stock is primarily intended for professional container nursery production and is particularly useful where plants require a structured growing medium for an extended crop cycle.
- Commercial nursery stock production
- Container-grown ornamental plants
- Shrubs and woody plants
- Perennial container production
- Young trees and larger nursery plants
- Container pots
- Larger decorative pots
- Professional landscaping plant production
Managing peat-free growing media successfully
Professional peat-free substrates may require a different approach to irrigation and nutrition compared with familiar peat-based mixes. The characteristics of the substrate, crop, container size, weather and production environment should all be considered.
Growers should monitor moisture throughout the root zone and adjust irrigation frequency and volume accordingly. The surface of a growing medium does not always provide an accurate indication of moisture deeper within the container.
Nutrition should likewise be matched to the crop and production system. Where controlled-release fertiliser or liquid feeding is used, the programme should account for crop requirements, irrigation strategy, container size and intended production period.
About Van der Knaap
Van der Knaap is an international specialist in rooting and growing media for professional horticulture. The company works with growers across a wide range of crops, developing substrate solutions around crop requirements and practical cultivation conditions.
Its expertise extends across potting soils and professional substrates, rooting media, coco products and organic fertilisers. Van der Knaap works with a range of natural substrate materials and develops mixtures according to the physical and nutritional requirements of different crops and production systems.
Research and crop testing form an important part of this approach. At its own 'de Kas' innovation centre, Van der Knaap carries out cultivation trials to investigate growing media, rooting products and new raw materials under practical growing conditions.
This work is particularly relevant as professional horticulture moves towards reduced-peat and peat-free production. Van der Knaap has been researching renewable and circular substrate materials, examining characteristics such as structure, moisture behaviour, pH and nutrition alongside their effects on actual crop growth.
For professional growers, that combination of substrate manufacturing, crop knowledge, research and practical cultivation experience makes Van der Knaap a strong partner when moving towards new growing media and more sustainable production systems.
