Weed Suppression on Pathways

Pilot project to promote innovative cultural tourism in rural areas

A nice footpath in the park of “Les Fougis”, which was originally 3 m wide – but without the use of glyphosate it looks like THIS after only a few years!

The challenge
Public Parks struggle to procure the resources necessary to prevent unwanted weed growth on the pathways. In addition, this situation has worsened due to new legislation which has banned the use of “roundup” (glyphosate).

Main idea

Sheep wool as a natural footpath covering to prevent weed growth in public parks; implemented at our sculpture park around the 16th-century castle “Les Fougis” in the French Auvergne

The pathway through the Wondrous Garden is shaped in the unusual form of a huge anchor.

Study of the idea’s feasibility through a three-year test on our 1.2 km footpath through the sculpture park. The idea is to create synergy—and consequently more public attention— between the following entities:


  1. A unique sculpture park surrounding a French castle which can attract tourists to the Allier department
  2. Wool as an innovative, ecological solution for weed prevention in this park and public parks at large
  3. Local agriculture and cultural tourism in the French countryside
  4. Scientific monitoring and analysis by universities

unsplash-logoTanner YouldRaising sheep is a principal agricultural activity in the French Auvergne (and in many other regions all over Europe); however, the use of sheep wool is poorly planned and very inefficient due to ecological and economic aspects. French farmers sell their wool for miniscule prices to China. Upon its shipping to China, the wool is transformed into insolation, and then it is shipped back to Europe. Using wool for weed prevention and footpath beautifying would be an innovative, environmentally friendly application of this raw material.

Association Purpose: The preservation of the estate “Les Fougis”, which curates and opens a unique sculpture park to the public.

Participents and Donators

Emmanuel Clayeux, a well-known racehorse-trainer in Vaumas/ France, donated a big amout of geotextile. This is spread out under the sheepwool so that no more weeds can grow through and the felt mat can later be easily turend.
Eleveur de moutons: Mister Allaix, at lieu dit Deyrand in 63230 BROMONT LAMOTHE, braught us a big amount of sheep wool on a truck right into the sculpture garden. While we unloaded everything together it was raining cats and dogs!
The Werwick Sheep from Scottland: This is an ancient race in nice brown and grey colours, which has been rediscovered recently. There exist only about 20 herds in France and Netherlands of these special sheep.
They rent holiday houses which You can find in 03210 Agonges and on the website www.lalue.fr You will be served with original roasted Werwick-Sheap here!

A) Documentation of the project

1. Definition of the technical requirements: Existing ground
2. Purchase and application of raw wool
3. Duration and conditions of entanglement/solidification (Felting?) to a closed cover on the walkways
4. Undesirable side effects (e.g. odor development or limited accessibility)
5. Eventual combination with other materials to harden the surface (solutions for wheelchair users)
6. Maintenance and care requirements
7. Influence of weather conditions on the felt cover
8. Weed prevention properties of the felt blanket
9. Aesthetic properties and visual changes in course of application
10. Perceptions of the visitors
11. Investigation of the change of the underground within 10 years
12. Changes in the thickness of the felt

B) Long-term documentation on the maintenance of the woolen path coverings

1. Possible growth of new weeds on/through the new felt cover
2. Repairing and thickening by re-felting more raw sheep’s wool
3. Cutting procedure to divide the continuous felt blanket into individual sections which could be rotated to renew weed preventative effects if necessary

C) Ecological documentation

1. Settlement of plants in the felt cover itself
2. Effects of the natural ingredients of wool on surrounding plants and soil
3. Settlement of new species

D) Cost and efficiency study of this model to maintain paths in public parks

1. Effort of the first installation
2. Effort for entertainment and care
3. Optional: Acquisition of a test herd of 20 sheep and a mobile fence for the production of new sheep wool and to “mow” the surrounding lawns in which the path is embedded

E) Final documentation of the project and the results
