Twig mats, or ready-made forest mats are lifted out of Finnish forests. The twig mat includes blueberry, lingonberry, lichen, crowberry, heather, moss, etc. depending on from where it is lifted. Twig mats are used when damaged yards are renovated or forest-like environments want to be created.
The weight of the twig mat depends on how wet it was when it was lifted. The twig mat needs sandy soil as its substrate. The product is not installed on humus. The product does not normally need to be attached to the ground. Wood fasteners can however be used on steep slopes. Initial watering is important for a twig mat, which is done similarly to grass transplants. When the product takes root, no watering is normally needed anymore.
