During the winter, the overground part of the plants is going to dry out, but this doesn't stop the root system and its associated bacteria from functioning properly. For aesthetic purposes and to encourage vegetative recovery, it is necessary to cut these dry parts at the start of springtime. These materials are ideal for compost or making mulch. In the past, reeds were also used to cover thatched cottage roofs.
