The report suggests using specific grass species for seeding highway verges to improve their quality and reduce maintenance needs. Grass seeds should be sown at a high density to protect the soil, with certain species limited to 5% of the mixture. Ideal seeding months are March-April and August-September, with topsoil containing over 1% organic matter. Different mixtures are recommended based on soil type, with additional grass species for rapid growth and weed control. Other proposals focus on maintenance and growth inhibitors.
