Mulches are materials installed under vine rows for several years to limit weed growth without the need for chemical inputs or mechanical tillage. Although their use is still limited due to the costs and constraints of installation, they offer various advantages for vines and the soil. There are two main categories of materials used: raw materials such as straw, wood shavings and chips, crop residues and compost and processed materials, such as organic films or felts made from hemp, maize starch or wool. Effectiveness, durability and cost vary according to the type of material. Some materials need to be renewed every year to ensure effective weed control.
